Water-damage-resistant sulfur modified asphalt mixture and preparation method thereof
The invention discloses a water-damage-resistant sulfur modified asphalt mixture, which comprises the following components in parts by weight: 95-100 parts of aggregate, 1-5 parts of modified sulfur and 3-8 parts of asphalt, wherein the modified sulfur is formed by polymerizing and modifying sulfur by using dipentene and 2-ethylhexyl acrylate, and the modified sulfur is prepared from the following raw materials in percentage by mass: 96% to 98% of sulfur, 1% to 2% of dipentene, 0% to 1% of 2-ethylhexyl acrylate and 0% to 1% of admixture. According to the sulfur-modified asphalt mixture, good high-temperature performance of the sulfur-modified asphalt mixture is guaranteed, the problem that the water stability of the sulfur-modified asphalt mixture is insufficient can be greatly solved, and the related preparation method is simple and suitable for application and popularization.
本发明公开了一种抗水损硫磺改性沥青混合料，各组分及其所占重量份数包括：集料95～100份，改性硫磺1～5份，沥青3～8份；改性硫磺利用双戊烯和丙烯酸异辛酯对硫磺进行聚合改性而成，所述改性硫磺采用的各原料及其所占质量百分比包括：硫磺96～98％，双戊烯1～2％，丙烯酸异辛酯0～1％，外掺剂0～1％。本发明所述硫磺改性沥青混合料在保证硫磺改性沥青混合料良好的高温性能的同时，可极大地改善硫磺改性沥青混合料水稳性能不足等问题,且涉及的制备方法较简单，适合推广应用。
