Effective Modeling of Extended Service Life for Pavement Treatments
This study determines the state of capital preventive maintenance (CPM) treatments used by Michigan local agencies and the extended service life (ESL) gained by applying CPM treatments to asphalt pavements. Local agencies in Michigan have actively used CPM treatments to maintain their asphalt pavements. Chip seals comprised the majority of CPM treatments used by the agencies in this study. According to the data collected, CPM treatments applied by local agencies provide at least four years of ESL on average, which is consistent with studies conducted at the Michigan Department of Transportation (MDOT) and outside the state. Data analysis has been restricted to distresses found in asphalt pavement, which is the primary pavement type owned by Michigan local agencies. This study shows that local agencies have the tools and data to analyze the ESL of their CPM treatments and that chip seal treatment yields a positive ESL. Further research is needed on the statistical significance of other CPM treatments and for making regional assessments.
