Dynamic Response of Roller-Compacted Concrete-Base Asphalt Pavement
This study aimed to investigate the dynamic response of roller-compacted concrete (RCC)-base asphalt pavement under traffic loads. Several strain and temperature sensors were embedded in a test road at different depths. The dynamic responses driven by truck passage were tested, and the effects of axle load, vehicle speed, vehicle type, and temperature on the dynamic response were investigated. The results showed that the transverse strain in asphalt surfaces was tensile, while the longitudinal strain alternated in tension and compression. The longitudinal and transverse strains in the base and subbase were in tension and compression, respectively, and the longitudinal strain was greater than the transverse strain. The tensile strain in asphalt pavement increased with decreasing vehicle speed, increasing axle load. When the axle weight of the truck was doubled, the tensile strain in the upper and lower layers of the asphalt pavement increased under low temperature and low speed conditions.
