Evaluation of Structural Benefits of Prime Coat Application for Flexible Pavements Using Accelerated Pavement Testing (APT)

This study was mainly focused on evaluating the structural benefits of a prime coat application that may positively affect pavement performance based on the pavement response measurements using Accelerated Pavement Testing (APT). Two full-scale field test sections were built using different interlayer conditions between Asphalt Concrete (AC) and base layer including prime coat and no treatment for evaluation. Strain gauges and pressure cells were instrumented for each test section to conduct pavement response measurements. Results indicate that the application of prime coat was able to significantly reduce stress and strain responses at critical locations of pavement structure by providing a structural bond between layers that result in enhanced pavement performance compared to pavement with no treatment. In addition, based on the results of relative performance estimated, it was found that pavement structures with prime coat application potentially lead to improved performance including fatigue cracking, top-down cracking and subgrade rutting compared to pavements with no treatment and pavement damage seems to be accelerated for pavement system without prime coat application. Also, the full-scale field tests conducted using APT were determined to be capable of effectively capturing the structural effect of prime coat application on change in pavement critical responses for enhanced performance of asphalt pavements with more realistic and reliable results.
