随着公路行车密度与负荷量的增大，铁路机车速度的提升，大型堤坝工程的兴建，以及大型喷气式客机对跑道和停机坪的高要求，专家们对工程压实和压实机械的重要性有了更深刻的认识。目前在公路建设中普遍采用了重型压实标准，建筑规范、建筑材料及施工工艺的不断更新，促进了压
With the increase of road driving density and load, the increase of railway locomotive speed, the construction of large-scale dam works and the high requirements of runway and apron for large passenger jets, experts are very important to the project compaction and compaction machinery Sex has a deeper understanding. At present, heavy compaction standards are commonly used in highway construction. Building codes, building materials and construction techniques are continuously updated to promote pressure
