Abstract:

In order to delay or eliminate the occurrence and expansion of the reflective cracking in the asphalt concrete overlay on old cement concrete pavement, an epoxy asphalt geogrid stress-absorbing layer(EAGSAL)was designed. The EAGSAL consists of epoxy asphalt and fiberglass geogrid. The pull-out test, skew shearing test, bending beam test and fatigue test were conducted to evaluate the performance of the EAGSAL and a traditional stress-absorbing layer(TSAL). The results show that the adhesive performance, shear performance, bending strength and fatigue performance of the EAGSAL with an optimal spraying volume of epoxy asphalt are better than those of optimally designed TSAL, and the maximum bending strain of the EAGSAL is very close to that of the TSAL. The EAGSAL has superior performance in reflective cracking resistance. Moreover, the EAGSAL with the optimal spraying volume of approximately 2.0 L/m² is thinner and lighter than the TSAL, which can decrease the thickness and improve the bearing ability of the whole pavement structure.
