Ultra-thin overlay technology is mainly used to improve the smoothness of the road surface and repair road diseases,im-prove the anti-skid performance of the road,and at the same time can also extend the service life of the road to a large extent.In order to study the technical performance of high viscosity asphalt,combined with the temperature,climate,traffic conditions and engineering material characteristics of the section from Bole Sitai to Sailimu Lake,starting from raw materials,the key indicators of high viscosity asphalt were studied,and it was found through tests that all indicators met the technical specifications of high viscosity asphalt,the pav-ing and rolling of the mixture elaborates the construction process of the thin layer overlay,and finally analyzes the flatness,anti-slip strength and structural depth,and the results show that:the thin layer overlay can effectively improve the skid resistance,flatness and structural depth of the pavement,thereby increasing the service life of the road.
