路基土及路面基层的压实度是工地实际达到的干密度与实试验所得的最大干密度的比值,而对沥青路面来说,压实度是指现场实际达到的密度与室内标准密度的比值。在介绍路基土、路面基层最大干密度及最佳含水量方法的同时,还对目前现场密度试验普遍采用的方法:环刀法、灌砂法、核子湿度密度仪法适用条件、仪器、方法步骤等做了详细介绍。 Subgrade soil and pavement compaction degree is the ratio of the actual dry density of the site to the maximum dry density of the actual test. For asphalt pavement, compaction refers to the ratio of the actual density of the site to the standard density of the room . In introducing subgrade soil, the maximum dry density of the road surface and the best method of water content at the same time, the current site density test commonly used methods: ring knife method, sand filling method, nuclear humidity density method applicable conditions, instruments, method steps Etc. made a detailed introduction.
