| Abstract: | In order to ensure the construction quality of roadbed,the compaction degree must be tested.This paper makes a comparative analysis of the test methods of compaction degree commonly used in the old and new“Field Test Methods of Subgrade and Pavement for Highway Engineering”of JTG E60-2008 and JTG 3450-2019,including the method of digging and filling sand and the method of settlement difference,and puts forward the highlights of the new procedures and the areas to be further studied and improved,which is helpful to better guide the field compaction degree test. |
