Research on performance of environment-friendly fume-suppression asphalt and optimization design for road
نویسنده
چکیده
Based on the analysis of the mechanism and hazards of asphalt fume, by adding two fume suppressant Mg(OH)2 and Al(OH)3 and two viscosity reducers Sasobit and ROADBIT-BPL, the paper optimized the mixture ratio for road use, and prepared the environment-friendly fume-suppression asphalt, and then conducted the performance tests to identify the optimum dosage. The results show that: the fume amount caused by the 10.0% dosage of Al(OH)3 will be reduced by 7.6% than the matrix asphalt; the admixture of the above two agents has negative effects on the asphalt anti-crack performance in low temperature. The anti deformation ability and high temperature stability of fume-suppression asphalt are relatively good in the optimized scheme 3.0%Sasobit+10.0% Al(OH)3.
