Abstract

The description, calibration procedures, installation and performance of the instrumentation used at the Virginia Smart Road to measure flexible pavement response loading. The measured horizontal transverse and longitudinal strains induced in the hot-mix asphalt (HMA) during compaction with a steel drum compactor both with and without vibrations. The data collected and used to determine the vertical compressive stress pulse induced by a moving truck at different locations beneath the pavement surface. It was found that HMA is subjected to very high horizontal strains during compaction especially when vibration is used.
