The types of rehabilitation activities that the City chooses to deploy can have a significant effect on the longevity of a pavement. Depending on the zone in which a pavement falls, a detailed rehabilitation strategy set needs to be formed. Common rehabilitation types include Stop Gap, Rehabilitation, Reconstruction, and Preventive Maintenance. It is the proper incorporation and application of M&R activities within the Preventative Maintenance category that a pavement management program leverages. Popular examples of cost-effective preventive activities include: • Crack and Joint Sealing • Microsurfacing • Rejuvenating agents • Patching • Fog, Slurry, and Chip Seals • Thin Overlays These activities help maintain and repair the surface integrity which can slow deterioration and depending on the treatment, also extend the life of a pavement. The outcome of this exercise is the long-term cost savings and an increase in network -level pavement quality over time. Figure 4 illustrates the concept of extending pavement life through the application of timely M&R activities. a Target Zone for '1 Pavement Preservation C: 65 0 0 v Target Zone for 4-1 v 45 Pavement Overlays v c� a Extended Life Target Zone for Pavement Rehabilitation & Reconstruction e] 20 Pavement Age (Years) Figure 4 - Pavement Life Cycle Curve 30 The best method to obtain the most optimal usage of available funds or to determine the required funding to achieve a predetermined level of service is through the use of a pavement management system. An effective pavement management system can assist agencies in developing an organized catalog of pavement assets, store periodic condition assessments, track spending and costs, compare trends in data, and assess the effectiveness of maintenance activities and new technologies.
