Analysis on the Application of Asphalt Fiber Chip Seal Coat in Expressway Maintenance
Based on the engineering practice,this paper selects SBS modified emulsified asphalt,glass fiber and basalt chip as raw materials for seal coat,summarizes and puts forward the construction technology of asphalt fiber chip seal coat according to the characteristics of raw materials.The test results show that the anti-skid performance of the pavement is improved and its water permeability is decreased after paving and curing the pavement with asphalt fiber chip seal coat.The use of asphalt fiber chip seal coat for construction has a good effect on promoting the development of highway maintenance technology and prolonging the service life of pavement.
