路基压实度检测方法与设备的研究

The Roadbed Compaction Degree Testing Methods and Equipment Research

路基压实度是路基施工质量检测的重要指标.目前路基压实度检测的主要方法有:灌砂法、环刀法和核子仪法等.目前公路建设中灌砂法是应用最广泛的压实度检测方法,但灌砂法也存在缺陷.基于此提出了1种新的路基压实度检测方法,并设计了1种路基压实度检测用取土设备.

The roadbed compaction degree is an important index on subgrade construction quality testing. At present,the main methods of the roadbed compaction degree detection are including as fellow：sand filling method,ring incision method,nuclear meter method,etc.At present,sand filling method is the most widely used in compaction degree testing of highway construction,but sand filling method also have defects.A new roadbed compaction test method was proposed in the article,and a earth-gathering equipment of roadbed compaction test with was designed.
