Abstract:

This paper evaluates the structural benefits of using perpetual asphalt pavement designs in comparison to the conventional pavement designs for three traffic levels. In addition, Life Cycle Cost Analysis (LCCA) was implemented to evaluate these various designs. Three scenarios were evaluated comparing the perpetual and conventional designs as applied on high, moderate and low traffic volume roads. The high traffic volume model represents a test section constructed on Highway 401 in Ontario, Canada. The moderate and low traffic volume scenarios were created based on traffic counts by the Ministry of Transportation of Ontario (MTO). Pavement designs for the moderate and low traffic volume scenarios are based on the American Association of State Highway and Transportation Officials (AASHTO) DARWin 3.1 methodology. The structural evaluation of the different pavement designs considered a 50-year analysis period using the Mechanistic Empirical Pavement Design Guide (MEPDG) model. The structural evaluation concluded that perpetual pavements have higher resistance to bottom up fatigue cracking, rutting and less deterioration rate of IRI compared to conventional pavements in the three scenarios. Finally, a 70-year LCCA was implemented on all three scenarios. The maintenance and rehabilitation programs used in LCCA were designed based on the MEPDG results and the typical MTO practices. The LCCA showed that perpetual pavement designs are the cost-effective alternative in high and moderate traffic volume scenarios.
