Capability Research Of Cement Pavement Adapting To The Heavy-weight Transportation

The thesis has a good research on the failures and experience in the Construction of Cement Concrete pavement in abroad. Based on this and the latest relevant research achivements in the world, it puts forward a kind of practicable constructure technique of cement Concrete pavement adapting to the heavy-weight transportation.First it analyzes the communication forms of Xuan Da freeway, introduces the experience of several provinces, which outstand in the Construction of Cement concrete pavement in China and makes a conclusion on the research results in the world. In this part, it demonstrates with sufficient argumenls in the aspects of material choice for the surface course, base course style, road drainage, etc.In theory it solves the troubles in the weak surface course, the weak base, the poor road drainage, etc.The thesis also debates on the exploration of constructive technique on the method of design of the cement concrete pavement based on the poor concrete base. Nowadays in our country this kind of technique attaches to much emphasis on Ihe theory analysis instead of practical experience. But it,s on the other hand in foreign countries, hi view of this, a me 1 hod of design of cement concrete pavement based On the poor Concrete base was proposed after calculating and comparing with different methods. It adopts the merits and discards the weaknesses of each technique both in theory and in experience. And it will offer a good reference to the Construction of Cement conorete pavement in future.
