Research for the maintenance and rehabilitation of pavement skid resistance are receiving increasing attention. The asphalt wearing course is one of the common maintenance methods to address road surface damage, provide a pavement with high roughness and improve skid resistance. To solve the problem of pavement skid resistance degradation after a period of service life, an asphalt ultra-thin wear course was developed using high viscosity asphalt and corn stalk fiber in this study. During the research, the performance of the corn stalk fiber modified ultra-thin wearing course was analyzed experimentally. The ultra-thin wearing course was used to treat a concrete pavement which skid resistance had reduced. The high temperature stability and water stability of the asphalt mixture modified by corn stalk fiber were improved. The corn stalk fiber can toughen and reinforce the asphalt mixture. Corn stalk fiber modified ultra-thin wearing course has excellent anti-slip properties, the texture depth has exceeded the specification requirements. After treat by corn stalk fiber modified ultrathin wearing, the British Pendulum Number (BPN) values of the pavement can still meet the requirements, and the Sideway Force Coefficient values (SFC) is improved by about 29.6%. The skid resistance of the pavement was significantly improved.
