The durability of semi-rigid base asphalt pavement can be enhanced by setting up graded crushed stone,but the frost heave is a problem when select the optimal type of graded crushed stone base.In this paper,three different type of graded crushed stone base (graded crushed stone base,graded crushed stone base with different cement content,asphalt-treated permeable base) were discussed by varying parameters.By using large Marshall sample after freeze-thaw cycles,this paper provided one better structure of pavement base for cold region.
