Dence Framework Cement Graval Grassroots Reserch

In the constrction of our country highway , Rigid material is used as highway road surface grass-roots unit material partly,And becoming peculiar important position at present in highways build more and more。Stable breakstone of cement grass-roots unit has higher intensity and load support capability , Show mainly in higher compression strength and stiffness,And have certain bending resistance pulling an intensity,And they all have follow an instar but unceasingly growing characteristic property,The stable breakstone of cement grass-roots unit bituminous pavement has less deformation and stronger load therefore generally diffusing an ability;and more, This material is better than being going in the field of stiffness other half rigid material。Despite of stable breakstone of cement blends material being used as road surface, grass-roots unit has as above a lot of merit occasionally, be not that possessions adopt cement to stabilize breakstone blending the road structure expecting acting as road surface grass-roots unit being able to gain expected effect。Primal problem that grass-roots unit there exists in specifically for our country cement stabilizes breakstone at present,System studies stable breakstone of cement collection expects that level matches for and designs method。Rigid material has very important practical or immediate significance to half in our country western part application.
