Research on Aggregate Gradation of Cement Stabilized Crush Stone

Cement stabilized crushed stone base is widely using in our country as a kind of good-performance semi-rigid base materials This paper analyzed the structure of 5 different aggregate gradation of cement stabilized crushed stone by using the design idea for SMA.Then,unconfined compressive strength tests were conducted.The findings of tests indicated that the cement stabilized crushed stone with framework-dense structure has higher strength than with suspending-dense structure,when they have same cement dosage.When the structure type of cement stabilized crushed stone changes from the traditional suspending-dense structure into the framework-dense structure,its mechanics performances are improved.
