在公路修筑中,压实机械是很重要的设备。无论路基、底基层、基层和面层都需要很好的压实,以达到一定的密实度,提高道路的承载能力,并防止沉陷、水分渗透等。一般压实工作量可占公路工程施工费用的2%左右。密实度每提高1%,基础承载能力就提高10%;沥青混凝土密实度每提高1%,承载
In highway construction, compaction machinery is a very important equipment. Both the subgrade, subsoil, grassroots and surface layers need to be well compacted to achieve a certain degree of compaction, improve the carrying capacity of the road, and prevent subsidence and moisture penetration. General compaction workload may account for about 2% of the cost of highway construction. Each 1% increase in the density of the basic carrying capacity increased by 10%; bitumen per 1% increase in density, bearing
