分析了一种新型沥青路面压实机械 (HIPAC)的特点 ,该机采用前后两条橡胶履带来代替通常的钢轮 ,对热沥青路面进行压实。试用表明它可较早对热沥青路面进行压实 ,有利于提高沥青路面的压实度和平整度 ,这是履带应用的创新 The characteristics of a new type of asphalt pavement compacting machine (HIPAC) are analyzed. The machine uses two rubber crawlers instead of the usual steel drum to compact the hot asphalt pavement. Trial shows that it can be hot asphalt pavement earlier compaction, is conducive to improving the compaction and flatness of asphalt pavement, which is the application of track innovation
