Through performance testing of laboratory prepared and on-site installed asphalt mixtures, the physical and mechanical properties under different processing parameters were studied, and the reasons were analyzed. At the same time, this paper discusses the key parameters such as filler temperature, viscosity of SBS modified asphalt, mixing time and quality during on-site construction. The research results show that moderate adjustment and optimization of processing parameters can significantly improve the physical and mechanical properties of asphalt mixtures, and enhance their water resistance and durability. Keywords: SBS modified asphalt, asphalt mixture, processing parameters, physical and mechanical properties Introduction SBS (Styrene-Butadiene-Styrene) modified asphalt is a widely used asphalt modifying agent that can enhance the performance of traditional asphalt mixtures. The high level of compatibility between SBS and asphalt makes SBS modified asphalt a popular choice for pavement construction, especially for the construction of high-end roads such as highways. However, the use of SBS modified asphalt also poses challenges to on-site processing due to its high viscosity, poor fluidity and low workability. In order to obtain satisfactory performance of SBS modified asphalt, it is necessary to optimize the processing parameters in on-site construction. In this paper, the on-site processing and optimization of SBS modified asphalt was studied, and the key processing parameters were explored in order to improve the performa
