One third of the total length of the Changde section of Hunan Province lacks hard pavement materials, but the soft feldspar weathering materials are quite abundant. Some work classes have used the weathering stone conservation pavement, the effect is very good. But not well summed up their experience. Last year, the Provincial Engineering Administration and Changde joint section of the joint section of Yangxi Bridge on the Changhuai Bridge paved 2.1 km of weathered stone abrasion and protective layer test pavement, passed the driving test, proved to be more successful. Therefore, this experience has been popularized in the total segment, and pavement technology
