Application of High-toughness Ultra-thin Asphalt Wear Layer Technology in Highway Maintenanc
With the gradual increase of traffic volume in Fengxian District of Shanghai,the standard of maintenance in engineering construction has also been improved.The practical application of 18～20 mm high-toughness ultra-thin asphalt wear layer technology in the construction of some sections of Pingzhuang Highway,Zhuangliang Highway,Hongzhu Highway and Tuanqing Highway in Fengxian District of Shanghai is introduced and summarized in detail.The key control points of material election,mix ratio and construction link are clarified,and the construction quality is evaluated.The acceptance result shows that the high-toughness ultra-thin asphalt wear layer has the strong performance of saving the materials,and also has the best properties of cracking resistance,seepage resistance,skid resistance and noise reduction,which is much better than the conventional asphalt pavement.This kind of technology is suitable for the roads with high quality and functional requirements,such as the trunk roads in the central urban area,provincial highways and highways with limited elevation,which lays the solid foundation for the future road maintenance work in Fengxian District.
