6 Paved Road Network Total Length = km Centre-Line MRN = 19.1 km Arterial = 4.1 km Collector = 20.7 km Local = 65.2 km Major Roads Road Class MRN Arterial Collector Local Lane 6

7 All Cracked Area (ACA) as a Measure of Pavement Condition Condition From ACA To ACA Colour V Good 0% 1% Good 1% 5% Fair 5% 10% Poor 10% 30% V Poor 30% 100% 7

8 Condition Cost of Maintenance & Rehabilitation Costs of Maintenance and Rehabilitation Good $1.50/l-m Crack Sealing High $25/m 2 Mill & Fill Critical Zone $65/m 2 Reconstruct Poor New Age of pavement Old Low 8

9 Critical Rehabilitation Timing Cracking 1-10% Good Condition Critical Poor New Age of pavement Old 9

10 Critical Rehabilitation Timing Cracking > 30% Good Condition Critical Poor New Age of pavement Old 10
