文章针对温拌剂在沥青中的应用特点,研究温拌剂加入沥青后制备的温拌沥青胶浆的行为特性,结果表明:Sasobit和Sasowarm温拌沥青胶浆的针入度、延度随温拌剂掺量的增加而减小,而软化点随着掺量的增加而增大,沥青胶浆的黏度变化在不同的温度呈现不同的变化规律;温拌剂的加入提高了沥青的高温性能,并且随掺量的增加而增强;但降低了沥青的低温性能,且胶浆的应变性随掺量的增加呈递减趋势;Sasowarm的高温及低温性能较Sasobit优良,2种温拌剂在沥青中的最佳推荐掺量为3%。
In this paper, according to the application characteristics of warm mix in asphalt, the behavior of warm mix asphalt mortar prepared by adding warm mix agent is studied. The results show that the penetration and ductility of warm mix asphalt mortar of Sasobit and Sasowarm vary with temperature The content of softener decreases, while the softening point increases with the increase of content, the change of viscosity of asphalt mortar shows different variation at different temperatures. The addition of warm mix agent improves the high temperature performance of asphalt , And increased with the increase of the dosage; however, the low temperature performance of the asphalt was decreased and the strain of the cement decreased with the increase of the dosage. The high and low temperature performance of Sasowarm was better than that of Sasobarm, The best recommended dosage is 3%.
