In recent years, along with the rapid development of economy in China, road traffic infrastructure has been well developed. In the construction of roads, the mixture of asphalt mastic and macadam becomes the wearing layer of most high-grade pavements due to its excellent comprehensive performance. The construction process usually comprises the steps of firstly spreading the mixture of the asphalt mastic and the macadam on an underlying pavement structure by using spreading equipment, and then rolling and forming by using a road roller. The asphalt film of the wearing layer of the asphalt mastic macadam mixture obtained by the method is thick, so that the skid resistance of a newly repaired road surface is poor before the asphalt film is worn by vehicles, and the driving safety of road vehicles is directly influenced. In order to ensure the initial skid resistance of the pavement in the traditional technology, a road designer usually takes a large value for the porosity of the asphalt mixture, which easily causes the pavement to be seeped, thereby causing the pavement to have defects of pits, looseness and the like, seriously affecting the service life of the road and increasing the use and maintenance cost of the road.
