Establishment of Performance Models and Effectiveness Evaluation of Pavement Maintenance Treatments at Different Traffic Levels

The present study established treatment family performance models of typical asphalt resurfacing treatments at different traffic levels. Investigated treatments include hot mix asphalt (HMA) overlay, mill & fill, micro surfacing and slurry seal. Regression analysis showed that using an exponential model instead of a linear model did not significantly improve the R-squares. Thus, linear treatment performance models were established in order to provide a rational base for performance prediction and treatment effectiveness analysis. In addition, a strong linear relationship was identified between pavement performance deterioration rate and traffic level. The treatment effectiveness was calculated as the area between pavement deterioration curve and the lower threshold. It was found that HMA overlay had the highest effectiveness, followed by slurry seal, mill & fill and micro surfacing. The two emulsified asphalt treatments (micro surfacing and slurry seal) had higher cost-effectiveness than the two HMA treatments (HMA overlay and mill & fill).
