摘 要: | 对比了高掺量回收沥青路面材料(RAP)的热再生混合料在旋转压实剪切试验机(GTM)旋转压实和马歇尔击实条件下的体积指标和压实参数.GTM 试验表明热再生混合料比非再生混合料容易压实,RA P掺量越大越容易压实,马歇尔击实法在设计高掺量 RA P热再生混合料存在局限性.并利用RAP的扫描电镜(SEM )照片分析了原因.

Abstract: | The paper compared the volume indicators and compaction parameters of central plant hot re-cycling mixture with high-content reclaimed asphalt pavement (RAP) at gyratory testing machine (GTM ) and Marshall compaction machine .The GTM experiments show that the hot recycling mix-ture is more easily compacted than non-renewable mixture ,the RAP content the greater the more easi-ly compacted ,Marshall compaction method has limitations in the design of high content RAP hot re-cycling mixture .the cause is analyzed from RAP scanning electron microscopy (SEM ) image . |
