Research on the construction technology of natural sand and gravel roadbed filling and compaction for expressway
To standardize roadbed construction,taking a highway reconstruction project as an example,research was conducted on the compaction construction technology of natural gravel roadbed filling.Before construction,the original ground of the roadbed should be cleaned and backfilled;using layered filling method for filling construction,pay attention to controlling the water content of the filling layer during the construction process;calculate the impact energy and speed of impact machinery during construction,and design impact compaction construction.The experimental results of practical application show that the designed construction method has good application effect,and this method can effectively improve the compaction construction quality of roadbed filling in complex geological environments,so that all indicators of the roadbed after construction meet the quality requirements.
