Accelerated Pavement Testing of Two Flexible Road Pavements to Assess Long-term Structural Performance

This paper presents the results of an accelerated pavement testing project conducted by Germany’s Federal Highway Research Institute (BASt). The main objective of the project was to evaluate the long-term structural performance of flexible road pavements under simulated heavy vehicle traffic. For this purpose two test sections of different strengths were subjected to dynamic impulse generator loading to simulate heavy vehicle loading. During loading, the condition of the pavement was monitored by periodic deflection measurements with a Falling Weight Deflectometer (FWD) and measurements of the transverse profile. Embedded sensors provided information on the dynamic mechanical response of the pavement under loading. The results showed a significant increase in the elastic strain at the bottom of the asphalt base course and a decrease in the bearing capacity. Furthermore structural bottom-up cracking in the asphalt base course was detected.A first approach to estimate the vertical propagation of cracks in asphalt pavement layers on the basis of the measured FWD surface deflections is presented.
