Effect of M-resin-based Stabilizer on the Performance of SBS Modified Asphalt

Industrial solid waste M-resin (MR) contains high sulfur content which was difficult to be comprehensively utilized. According the vulcanization reaction mechanism, MR used as vulcanizing agent, nano zinc oxide (ZnO) an activator, tetramethyl thiuram disulfide (TMTD) accelerator produce M-resin-based stabilizer. (0.5, 1, 1.5, 2, 2.5), ZnO (0.1, 0.2, 0.3, 0.4, 0.5) and TMTD (0.06, 0.08, 0.1, 0.12, 0.14) were mixed with different contents, a three-factor five-level orthogonal experiment designed test penetration, ductility, softening point 48 h difference of SBS modified asphalt. Based on four indexes, basic formula stabilizer obtained. The influence kaolin, auxiliary material, thermal stability compared, optimized, appropriate dosage determined. microscopic morphology asphalt developmental fineness analyzed fluorescent microscopy technology, studied generated binary graph skeleton graph. DSR carried out detect rheological properties dosages MR-based stabilizes. results show that can significantly improve storage ratio MR:TMTD:ZnO:Kaolin is 1.5:0.5:0.08:12, 1.02 %. reduce 33.6 ℃, increase 13.6 decrease penetration degree 9.7 mm, but it has little effect 5 ℃ ductility index. images cavity two-phase continuous network structure formed inside under 2.36 μm, uniformity good. also shows effectively temperature performance
