Desert Area Of ​​highway Subgrade Compaction

There is not systemic research on arts of crushing speedway roadbed with aeolian sand in desert in our country.Though the examination, theory analysis and test-road, the paper brought forward the aeolian sand maximum dry density by method of bottom vibration. And the maximum dry density that Aeolian sand is vibrated at the state of dry is the parameter of control quality of crushing the roadbed. We also brought forward the machine that adapt to crush Aeolian sand roadbed are bulldozer, double-driver road roller. We study their parameter of working.We sum up the all arts of crushing the speedway roadbed with eolian sand in desert, base on theory analysis and testing arts of crushing under different crushing machine and different state of Aeolian sand on Yujing desert speedway.
