路基干湿类型对路基有何影响(国外英文资料) The packing particle size must not be greater than 15cm. The method of filling the rock and foundation is vertical, the method of lamination, the impact compaction and the strong compaction. The vertical filling method (pour filling method) is mainly used for secondary and secondary and laying low pavement under the highway in the steep slope construction particularly difficult or fill sections on lots of blasting to dig, and unable to struggle up the steep slope of the embankment of bottom-up hierarchical operation, broken rock, mud and water rock fill embankment. The method of construction of the method is more stable and stable. The layered compaction method (roller compacting method) is widely adopted and can guarantee the quality of the stone embankment, and the method is layered and compacted at the bottom level. This method is used for highway, first class highway and other grade road embankments on the advanced road surface. The stone embankment is divided into four stages, four working sections and eight process processes. Regarding the filling embankment, the technological process is: the construction preparation, packing for shipment, layered filling, laying flat, vibration rolling, detection sign recognition, forming, roadbed subgrade repair. This paper briefly describes the method of excavation of soil by bulldozers. The bulldozers excavate the soil for a cycle by cutting soil, transporting earth, unearth, regress (or return-back), and empty back. The main factors that affect the efficiency of the operation are the soil and the soil. Therefore, it must be covered with the minimum amount of time and distance, and as much as possible to minimize the loss of soil during the push. Bulldozers, digging soil cutting operation method and the method of filling subgrade the same is downhill bulldozing, slotted bulldozing, tied for bulldozing, relay bulldozing the wave bulldozing method. There is also inclined shoveling soil method and side
