摘要 利用马歇尔稳定度以及冻融劈裂试验,单轴压缩回弹模量试验,间接拉伸回弹模量试验以及四点弯曲小梁疲劳试验等,评价和分析了不通石墨掺量改性后的沥青混凝土的路用性能.研究发现:采用连续级配AC-20和间断级配Sup12.5均可获得同时具有优异电学性能和路用性能的沥青混凝土.石墨掺杂沥青混合料的抗水稳定性能力好,间接拉伸模量高,疲劳寿命长,抗高温稳定性能较好,可以作为新型路面在实际工程中应用. The continuous mix proportion such as AC-20 and discontinuous mix proportion such as Superpave 12.5 are employed to prepare electrically conductive asphalt-based composite(ECABC).Experimental results of Marshall Remnant Stability Test,Four Point Bend Fatigue Test,Indirect Tensile Modulus Test and Rutting Test show that graphite modified ECABC possesses of high resistance to moisture damage and resistance to fatigue damage,high resilient modulus and excellent high-temperature stability,which is expected to apply as new-type pavement.
