3 Chapter 1 Introduction ADOT already inspects the condition of its maintained features under its AAA+ program. Updated condition survey procedures will help ADOT move towards level-of-service-based (or LOS-based) program budgeting. This chapter introduces the updated data collection procedures and compares them to those now used. The new procedures build on ADOT s current approach, but simplify and reduce effort through random sampling. 1 Updated Data Collection Procedures ADOT Maintenance has measured the condition of highway features for its AAA+ program for several years. These measurements have been based on the number of features passing a threshold value, or functioning as intended FAI. When compared to the total inventory of that feature, the ratings have been expressed as a percentage. The percent passing could be interpreted as a maintenance level of service. Ratings could also be expressed in the opposite sense, reporting the percentage not functioning as intended, or percent NFAI. ADOT is working to tie levels of service, or LOS, explicitly to maintenance budgeting. Development of a LOS-based budgeting procedure will require some changes in how data on the maintained condition of highway features are collected and reported. Not everything will be changed for example, surveys of vegetation and landscaped areas will be carried out and reported as they have been. In other ADOT Maintenance Data Collection Guide 1-1

4 INTRODUCTION cases LOS values will be computed from data already available in the districts or central office. Even for items where reporting of condition data will change, the maintained features themselves are much the same as those measured in the past, and many guidelines for measurement will likewise be similar to those used in the past. The key changes are as follows: Condition ratings will no longer be reported as functioning as intended or not functioning as intended ( FAI and NFAI ). Rather, condition values will be reported simply as the range of values observed in the field. They are clarified in chapter three (3). The length of highway covered in each annual survey will be reduced by using a sampling approach. Sample sections will be 0.5-mile long. The samples are randomly generated each year using the Maintenance Budgeting Program (MBS). This one change should save significant time and effort. In a few cases there are additional items to be measured, which have not been done in the past. These include conditions of paved surfaces that are important to maintenance but that are not tracked in ADOT s pavement management system, and delineators. 2 Moving to a Graded Approach Maintenance levels of service, or LOS, will be reported differently as part of the linkage to budgeting. In the past LOS has been expressed as the percentage of items passing or FAI, as explained above. In the new approach, LOS will be expressed as letter grades A, B, C, D and F. Plus-and-minus grades may also be used if finer gradations are needed. The updated data collection procedures will support these graded LOS values. 3 Quick Points on Sampling Overview All field inspections of maintained features will take place in highway sample sections that are each 0.5-mile long. A total of a few hundred sample sections will be inspected each year, based on statistical design as well as resources available for conducting the survey. These samples will provide an indication of the total network condition statewide. Samples will be selected in each route under the responsibility of a roadway org this will ensure that highways of different functional classes and geographic locations are sampled each year. The location of the sample section will be selected randomly each year this ensures diversity in the sample set and avoids bias due to unique conditions that may exist at particular locations. ADOT Maintenance Data Collection Guide 1-2

5 INTRODUCTION A randomly selected sample set will be generated each year, and a list of sample sections will be provided to each org. The sample sections will be identified by route and beginning milepost. The length of highway to be inspected will be 0.5 mile, moving in the cardinal direction (increasing mile posts) from the assigned milepost. Only one exception will permit moving this sample section in the field existence of a construction work zone. In this case the sample should be shifted in 0.1-mile increments in the cardinal direction (increasing mile posts) until the sample section no longer includes a work zone. If the construction is at the end of the route; in this case the sample should be shifted in 0.1-mile increments in the non-cardinal direction (decreasing mile posts) until the sample section no longer includes a work zone. If this is the case make sure you notify all other orgs that are inspecting this segment, so everyone is inspecting the same segment. Inspecting a Sample Section The sampling approach changes the way in which data will be collected at the site. Refer to the highway configuration in the sample survey section on the following page. Important points to note: The length of the sample section is 0.5 mile. The width of the sample section extends from right-of-way line to right-of-way line. [(C) And (D) in the sample section on the following page.] Only features that are within this sample area and are maintained by ADOT should be inspected. The sample area will contain the mainline highway lanes and shoulders (A), a frontage road if present (B), adjacent right-of-way, and a median in the case of divided highways. The survey will cover features on all these components within the survey area. Quantities of features will be summed across these components if needed (e.g., pavement surface area will include the sum of the paved areas of all roadway lanes and paved shoulders on all roads). If the section includes an intersection, inspect all ADOT maintained features within the mainline right-of-way except traffic signal equipment (E) and Bridge Decks. Interchange ramps (F), acceleration and deceleration lanes, truck lanes, and turning lanes should be included in the survey. When counting the lanes in the survey section, all of these features should be included as a lane. The sample segment has 7 lanes 4 mainline lanes, 2 frontage road lanes, and 1 ramp. If at either end of ramp there are multiple lanes, count all lanes. If there is a partial lane and there is 2 tenths of a mile or more count it as a lane. Within the sample area, complete the items on the Roadway Survey and the Signing and Striping Survey forms as explained in Chapter 2. In some cases, it may be necessary to count all eligible inventories and then divide the number of deficient inventory by the number of all eligible inventories. ADOT Maintenance Data Collection Guide 1-3

6 INTRODUCTION For example, Survey Item 7 - Unpaved Shoulder Edge Drop-Off, inspectors are asked to estimate the percent of the total length of shoulder with erosion or edge drop-off greater than 2. It is necessary to measure the total length of unpaved shoulders. In the sample section below, there are shoulders on both sides of both lanes of the mainline; both sides of the frontage road; and both sides of the ramps. Once the total length of shoulders is known, divide the total length of eroded shoulder by the total length of shoulders. Example: 4 mainline, 2 ramps, 2 frontage shoulders. The length of the mainline is 2.0 miles, the length of the ramp is 0.4 miles and the length of the frontage is 0.6 miles. This equals 3.0 miles total length. For example, total eroded shoulder equals 1.1 miles (5808 linear feet). Calculation: ( )*100 = 36.67%, so you would circle 30-50% for survey item 7. Sample Survey Section Survey Length = 0.5 Mile A A F E D B E Survey Width = ROW to ROW C ADOT Maintenance Data Collection Guide 1-4

7 INTRODUCTION Acknowledgement The criteria to be used in rating items are based, as closely as possible, on the criteria used in previous AAA+ inspections to maintain continuity. The authors wish to acknowledge the work of Ms. Jani Demaree of ADOT as the source of the photographs and many technical descriptions of features in the following sections. These descriptions have been adapted to conform to the new survey procedures and LOS reporting developed in this study. ADOT Maintenance Data Collection Guide 1-5

9 Chapter 2 Survey Forms Inspection results will be recorded on survey forms. These forms provide spaces for general information on the sample segment and for ratings for each survey item. Any extra notes can be written on the back of the sheet. 1 Forms Two separate survey forms should be filled out for each sample segment: A Roadway Maintenance Survey Form, which includes roadway surfaces and shoulders, both paved and unpaved, and roadside, safety, and drainage features; and A Signing and Striping Survey Form, which includes four items related to signing and striping. ADOT Maintenance Data Collection Guide 2-1

10 FORMS Roadway Maintenance Survey Form Signing and Striping Survey Form Chapter 2 provides general instructions for filling out the forms. Detailed descriptions of how to measure each item on the forms are provided in Chapters 3 and 4. The following must be noted on the forms. Date, Inspector, and Phone Number of the person taking the measurements. Org. number; (for the Sign & Striping Form also provide the Roadway org number). Route. Beginning mile post. Total number of lanes in both directions. (Interchange ramps, frontage road lanes, turning lanes, truck lanes, etc. should all be counted as a lane.) Do NOT include Left or Right distress lanes in this count. This is not included on the Signing & Striping form. Identify on the Roadway Maintenance Survey Form which part of the segment is Asphalt or PCCP, utilizing the check boxes provided. Complete survey form on the sample segment. ADOT Maintenance Data Collection Guide 2-2

11 FORMS Select a rating for each item that is relevant to the sample segment. In most cases, you can select a rating by circling the appropriate description or range of values. In cases that have both, Asphalt and PCCP surfaces, place a checkmark to the left of the area where it is located. (Usually there will be only one type of Surface). For some items you are asked to count deficiencies and print this number on the form. A check box is provided if the number of deficiencies exceeds a stated maximum value. For example, suppose you are counting spalls as part of Item 5 PCCP: If the number is less than 20, you would print it in the space provided. ADOT Maintenance Data Collection Guide 2-3

12 FORMS If the number is greater than 20, you would put an X in the box in the final column. For Item 6 Unpaved Shoulder. Circle the statement which represents the segment being measured. If there is NO shoulder at all in the segment place an X in the N/A column. For Item 7 Unpaved Shoulder. Circle the percentage which represents the segment being measured. If there is curb with guardrail in the entire segment put an X in the N/A column. ADOT Maintenance Data Collection Guide 2-4

13 FORMS Place an X in the N/A column if any of the items are absent from the sample segment. For example, if inspecting a segment that does not have any crash attenuators present, you would place an X in the N/A column next to Item 10. Description of filling out the Sign & Striping form Fill out the top portion of the inspection form as directed on page 2-2 of this guide. Indicate what portion of the right of way you are inspecting by placing a check mark in the box(s) located left of Mainline, Frontage, & Ramp. Select a rating for each item that is relevant to the sample segment. In most cases, you can select a rating by circling the appropriate description or range of values. ADOT Maintenance Data Collection Guide 2-5

14 FORMS In the case of Item 1, enter the total number of sign posts that are located in the sample segment and enter the number of bent or damaged posts. In the case of Item 4, if the item is not present at the location you are inspecting place an X in the N/A column. ADOT Maintenance Data Collection Guide 2-6

15 Chapter 3 Roadway Features Survey The Roadway Maintenance Survey Form includes roadway surfaces and shoulders, both paved and unpaved, roadside, safety, and drainage features. 2 Pavement and Shoulders Item 1, Asphalt Pavement, Unfilled Potholes: Count the number of unfilled potholes in all lanes of all roads within the sample area. Enter the total on the form if fewer than 20, write the number in the space provided. If greater than 20, simply check the box at the far right no need for an exact count. Beginning of a Pot Hole Pot Hole ADOT Maintenance Data Collection Guide 3-1

16 ROADWAY FEATURES SURVEY Item 2, Open or Unsealed Cracks in Asphalt Pavement: Open or unsealed cracks are those that have not been previously sealed, or that have been sealed but are now reopened. This inspection category has three entries, one for each of the following types of cracking: a) Alligator Cracking: Alligator cracking typically occurs only in the wheelpaths of roadway lanes (travel lanes only). Estimate the total area of pavement in which open alligator cracking occurs in at least one wheelpath. For this particular type of cracking, do not consider shoulders. For example: there are 4 wheelpaths, or 8 wheelpath halves illustrated below. Three of the wheelpath halves have alligator cracking. Three divided by 8 is 37.5%. In this case you would circle 30-50% on the inspection form. Alligator Cracking Example Mainline Shoulder Alligator Cracking ADOT Maintenance Data Collection Guide 3-2

17 ROADWAY FEATURES SURVEY Alligator Cracking Bad Alligator Cracking b) Other Cracking, Less Than and up to ¼ Wide: Other cracking includes longitudinal, transverse, diagonal, and other cracking, but not alligator cracking. Cracking less than ¼ wide includes hairline cracks and early stages of open cracks. Estimate the total percent area of paved lanes and shoulders on all roadway area that exhibits open cracking of less than ¼ width. Example: If the segment has two lanes, linear feet of continuous cracking would equal 0-5%, linear feet of cracking select 5-10%, feet of cracking select 10-30%, feet of cracking select 30-50%, anything greater than 2640 linear feet of cracking select >50% on survey form. Up to ¼ wide cracking Up to ¼ wide cracking ADOT Maintenance Data Collection Guide 3-3

18 ROADWAY FEATURES SURVEY c) Other Cracking, Greater Than ¼ Wide: Other cracking includes longitudinal, transverse, diagonal, and other cracking, but not alligator cracking. Cracking greater than ¼ wide includes open cracks of pencil-width or greater. Estimate the total percent area of paved lanes and paved shoulders on entire sample segment that exhibits open cracking of greater than ¼ width. Example: If the segment has two lanes, linear feet of continuous cracking would equal 0-5%, linear feet of cracking select 5-10%, feet of cracking select 10-30%, feet of cracking select 30-50%, anything greater than 2640 linear feet of cracking select >50% on survey form. Greater than ¼ wide cracking Greater than ¼ wide cracking Make sure all 3 types (a through c) of cracking are noted on the survey form. Item 3, Percent Asphalt Surface with Bleeding: Estimate the percent area of all asphalt pavement that is bleeding. Using the same scoring method as Other Cracking (b) and (c). Bleeding Bleeding ADOT Maintenance Data Collection Guide 3-4

19 ROADWAY FEATURES SURVEY Item 4, Percent Asphalt Surface with Raveling: Estimate the percent area of all asphalt pavement that shows wear caused by the loss of aggregate and binder. Raveling Raveling Item 5, Portland Cement Concrete Pavement: Number of Spalls and Faulted or Settled Joints: Count the number of spalls, uneven joints, and open cracks other than joints in all PCCP-paved areas on all lanes in the survey area. Enter the total on the form if less than 20, write the number in the space provided. If greater than 20, simply check the box at the far right no need for an exact count. Note: if there is PCCP there usually isn t Asphaltic Concrete. If both PCCP and AC are present in the survey area please note this using the check boxes on the form. Spalls in need of repair Spalls in need of repair ADOT Maintenance Data Collection Guide 3-5

20 ROADWAY FEATURES SURVEY Spalls in need of repair Spalls in need of repair Item 6, Unpaved Shoulder: Unpaved Shoulder is the unpaved portion beginning at the edge of pavement (EOP) on one or both sides of mainline. Some unpaved shoulders may have 2 feet in width, and some may have 10 feet or greater in width. If there is NO shoulder (i.e. room for a vehicle to get off of the roadway) in the sample segment place an X in the N/A column. Evaluate the condition of the unpaved shoulder surface in the survey area in terms of smoothness of ride and need for grading or repair. Do not include in the inspection shoulders behind curbs or guardrails. ADOT Maintenance Data Collection Guide 3-6

21 ROADWAY FEATURES SURVEY Unpaved Shoulders Example Edge Striping Inspect unpaved shoulder No unpaved shoulder inspection because guardrail abuts pavement Legend Pavement Unpaved Shoulder Guardrail Paved area is from EOP to EOP Item 7, Unpaved Shoulder Edge Drop-Off: Estimate the percent of the total length of shoulder with erosion or edge drop-off greater than 2. Estimate the percent of the total length of shoulder with erosion from the edge of roadway, including behind curb and guardrail. Erosion is soil displacement due to water or wind disturbance. Shoulder drop-off is a change in elevation along the edge between a paved surface and an unpaved shoulder, usually at an angle from the horizontal of 45 degrees. This includes drop off adjacent a cut ditch. Measure drop off where there is a rolled curb that does not have guardrail. Do not measure drop off where there is curb with guardrail. Circle the combine totals of Erosion and Shoulder Drop-off on the survey form. ADOT Maintenance Data Collection Guide 3-7

22 ROADWAY FEATURES SURVEY Drop-Off Does Not Exceed 2 Inches Drop-Off Exceeds 2 Inches Erosion Erosion 3 Roadside, Safety, and Drainage Item 8, Guardrail: Estimate the percent of the total length of guardrail with one or more of the following deficiencies: Broken or bent rails; Broken or bent posts; Severe corrosion; Loose or broken bolts; or Any other condition requiring repair. ADOT Maintenance Data Collection Guide 3-8

23 ROADWAY FEATURES SURVEY Guardrails are used to separate travel lanes from oncoming traffic and to protect traffic from bridge ends and piers, deep fill sections, and other potentially dangerous locations. Inspect all guardrail types (W-Beam, Tri-Beam, Ribbon, Half Moon, etc.) EXCEPT cable barriers, which are included in another survey. When estimating guardrail length, it is sufficient to count panels (12.5 ) rather than measure exact lengths. In Good Condition Broken or Bent Elements ADOT Maintenance Data Collection Guide 3-9

24 ROADWAY FEATURES SURVEY Item 9, Guardrail and Barrier End Treatments: Indicate if any guardrail or barrier end treatments are missing or damaged. Inspect all end types (extruder terminals, "turned down" sections, cable anchors, sloping concrete end sections, etc.) EXCEPT cable terminals, cable anchors, and terminal anchor ends. Terminal anchor ends are considered to be part of the rail. BCT in Good Condition Missing or Damaged Extruder in Good Condition Extruder Damaged Extruder Back Side DO NOT Measure This Type as an End Treatment ADOT Maintenance Data Collection Guide 3-10

25 ROADWAY FEATURES SURVEY Item 10 Crash Attenuators: Indicate if any crash attenuator elements need repair. Crash attenuators may consist of plastic barrels filled with sand or water or metal units resembling guardrail in a special shock-absorbing configuration. They are placed at interchanges at gore points, usually at on/off ramps, bridge piers, or other obstacles. Damage may consist of broken or tipped-over barrels, loss of filler material, missing lids, or any other condition requiring repair. Barrels In Good Condition Barrels Needs Attention Attenuator In Good Condition Marking is Wrong Attenuator Needs Attention Attenuator In Good Condition Attenuator In Bad Condition Old Attenuator In Good Condition Attenuator In Good Condition ADOT Maintenance Data Collection Guide 3-11

26 ROADWAY FEATURES SURVEY Item 11, Sweeping: Indicate whether the sample segment requires sweeping of litter, dirt, or debris. This item is for PHOENIX & TUCSON METRO AREAS ONLY In Good Condition Needs Sweeping Item 12, Litter: Estimate the amount of litter on or beside the roadway using one of the following designations: No litter - All litter has been removed. Few pieces - Some litter is present, but not distracting from view. Small patches Litter is present in 20% of the area. Unsightly areas Litter is distracting and present in 30% to 50% of the area. Greater Than Half the area Litter is present in more than half of the area. In Good Condition N litter Small Patches ADOT Maintenance Data Collection Guide 3-12

27 ROADWAY FEATURES SURVEY Few Pieces Unsightly Areas Item 13 Fence Panels: Estimate the percent of fence panels missing or damaged. Inspect all chain link and barbed wire fence within the sample section that is maintained by ADOT. In Good Condition Cut or Stretched Wires, Bent Posts, Opening Under Fence ADOT Maintenance Data Collection Guide 3-13

28 ROADWAY FEATURES SURVEY Buried Fence Erosion Below Fence Item 14, Lined Channels: Estimate the percent length of line channels with debris or vegetation. Open channels are typically lined on both sides and the bottom with concrete (three sided channels). They serve to carry water away from the road into a natural water course. Lined channels can run parallel to the road within the right of way or at acute angles to the road. Unpaved and rock covered channels should be inspected as part of Item 15 Unpaved Bladed Ditches. DO NOT inspect lined stream beds or wash channels. In Good Condition 0-5% With Vegetation or Debris 5-10% ADOT Maintenance Data Collection Guide 3-14

29 ROADWAY FEATURES SURVEY Lined Channel 30-50% Lined Channel >50% Lined Channel >50% Un-lined Channel with Concrete Bottom ADOT Maintenance Data Collection Guide 3-15

30 ROADWAY FEATURES SURVEY Item 15, Unpaved Bladed Ditches: Estimate the length of unpaved bladed ditches with rock, mud slides, debris, or vegetation that will hinder drainage. Unpaved drainage channels run along the roadway and serve to carry water away from the road into natural water courses. Drainage ditches can run parallel to the road within the right of way, or at acute angles to the road. Include all grader ditches (crown ditches) in the inspection. DO NOT inspect stream beds. In Good Condition With Vegetation or Debris Crown Ditch With Vegetation or Debris ADOT Maintenance Data Collection Guide 3-16

31 ROADWAY FEATURES SURVEY Item 16, Pipe Openings, Down Drains, and Other Drainage Features: Estimate the percent of all other drainage features that are silted to a depth >25%. These features include pipe openings, culverts, down drains, drop inlets, catch basins, etc. Culverts and pipes may be metal or concrete conduits crossing under the road or may be used to extend ditches under crossroads or driveways that connect to the road. Their purpose is to carry water through the right of way and away from the road with as little disturbance to the roadway facility as possible. Pipes and culverts may be found as a single unit or in an array containing several units, or "barrels". They may be cylindrical, oval, square, or rectangular in cross-section. Drop inlets and catch basins are drainage devices that collect and divert water. They are usually found on roadside with curb and gutter, median, and in populated areas where water discharge must be more carefully controlled. Drop inlets and catch basins are connected to pipes that convey the water into nearby drainage channels. Count the number of openings in the segment. Divide the total number of openings silted 25% or greater by the total number of openings. Example: A four box culvert would have 8 openings. A single pipe would have 2 openings. A drop inlet or catch basin would have 2 openings, one at the top and one connecting to the pipe or box culvert under the roadway, or down the side of the road. The total in this example is 12 openings. If 4 to 6 openings were silted greater than 25% you would circle 30-50% on the survey form. In Good Condition Silted Pipe opening silted more than 25% Pipe 0-5% Pipe 5-10% ADOT Maintenance Data Collection Guide 3-17

33 Chapter 4 Signing and Striping Survey The Signing and Striping Survey Form includes four items to be rated, all in daylight. A detailed description of the items on the form is provided in Chapter 2. This chapter provided general instructions for filling out the forms. Date, Inspector, and Phone Number Org. number; for Sign & Striping Form also provide the Roadway org number also. Route Beginning mile post. If different from the segment given at training contact the Roadway Org and Interstate Orgs to make sure the same sample segment is being inspected. Check the appropriate box to identify Mainline, Ramp, or Frontage roads in the sample segment. If there is more than one road type in the sample area, check the respective boxes. Example; if interstate personnel are inspecting just the mainline they would only check the Mainline box. If Regional orgs are inspecting the frontage road and ramps they would check the Frontage & Ramps, boxes. If they were inspecting Mainline, Frontage and Ramps all boxes would be checked. When the two forms from Interstate Crews and Region Crews are looked at together, the checked boxes should coincide with each other. Provide information for the sample segment ADOT Maintenance Data Collection Guide 4-1

34 SIGNING & STRIPING Item 1, Sign Posts: Enter the total number of sign posts in the sample section and number of posts that are bent, damaged, missing or need repair.
