摘要
Abstract
Using a combination of numerical simulation and in-house tests,the influence of rubberized asphalt stress absorption layer on the mechanical properties of asphalt pavement was studied,and the optimal amount of rubberized asphalt and the optimal full coverage rate of crushed stone were analyzed.The results show that the installation of a rubberized asphalt stress absorption layer on an asphalt pavement will increase the surface deflection and bottom shear stress of the asphalt layer,while reducing the bottom tensile stress.The layer thickness should not be set too large,and the optimal amount of rubberized asphalt is 2.2 kg/m2,while the optimal full coverage rate of crushed stone is 70%.关键词
