| 摘 要： | 目前常用的沥青改性方案有两种,分别是直投式改性与预拌式改性。该文通过室内试验和实体工程,分析了RST直投式改性剂的改性机理,证明直投式改性剂在沥青中的分散均匀性。同时,对两种方案下的材料选择和混合料生产过程中的节能效果进行了量化计算。

Analysis of Straight Casting Asphalt Modifying Scheme and Its Energy-saving Effect |
| |
| Abstract: | At present,there are two normal asphalt modifying schemes,separately being the straight casting modifying one and premixing modifying one.The article analyzes the modifying mechanism of RST straight casting modifying agent to prove the dispersing evenness of straight casting modifying agent in the asphalt.At the same time,the selection of materials under two schemes and the effects of energy saving in the course of mixture production are quantified and calculated. |
