Research on Construction Technology of GAC-16C Modified Asphalt Mixture
In order to study the feasibility of the application of GAC-16C modified asphalt mixture in municipal road engineering,the road per-formance of SBS modified asphalt mixture and additive modified asphalt mixture(matrix asphalt+rutting agent)was compared and analyzed in this paper,and the composition and application of the mixture material were studied.The results show that with the increase of anti-rutting a-gent,the road performance of each mixture is greatly improved,but when the content exceeds 0.4%,the performance decreases to a certain extent,so the content of anti-rutting agent is determined to be 0.4%.Compared with SBS,the high temperature stability and water damage re-sistance are improved,while the low temperature performance is decreased,that is,the flexural tensile strength and the maximum flexural ten-sile strain are reduced by 11%and 10%respectively.The construction of the test section of GAC-16C modified asphalt mixture effectively verifies the rationality and feasibility of the construction technology,and provides a solid and reliable basis for the popularization and applica-tion of the subsequent mixture in a wide range.
