Study on Road Performance of Crumb Rubber Modified Asphalt Mixture
In order to ensure the sustainable,high-quality and green development of road engineering construction in China,based on the advantages of the domestic market,this paper uses domestic raw materials and 15%waste rubber powder modified asphalt to mix AC-13(C)and SBS(I-D)SMA-13 mixtures respectively,and tests the road performance indexes of the mixtures according to the current specifications.The test results show that the high temperature stability and water damage resistance of the dense graded waste rubber powder modified asphalt mixture are greatly improved compared with the matrix asphalt mixture,which is basically close to the SBS(I-D)modified asphalt mixture.The low temperature crack resistance shows good road performance and is more suitable for areas with large temperature differences.The research content of this paper can provide reference for the application of waste tire rubber powder modified asphalt mixture.
