通过室内实验方法模拟沥青路面在外界自然条件下的光老化,然后对比不同级配的混合料在老化后的孔隙率的分布情况,得出了开级配和半开级配空隙率在不同光照条件下的变化情况,并分析其原因,对今后沥青路面施工具有一定指导意义。%The paper simulates the photooxidation aging under the natural condition by the indoor experiment methods,compares the distraction after the aging of the mixtures with various gradations,concludes the changes status of the open-graded and semi-open-graded porosity under various sunlight conditions,and analyzes the reasons,so as to have certain direction significance for the asphalt pavement construction in future.
