摘要
为降低能源消耗、减少环境污染,使用壳牌成品温拌沥青,可以免去温拌沥青混合料试验(施工)过程中添加温拌剂的环节,而且成品沥青只需要加热到较低的温度即可顺利进行试验(施工).分别对壳牌成品温拌改性沥青混合料和热拌改性沥青混合料进行对比试验,以评价它们的路用性能.试验结果表明,两者路用性能相似,而壳牌成品温拌改性沥青混合料的疲劳性能更加优异.
Using of Shell-finished warm-mix asphalt(WMA) can not only remove the link of adding warm-mix additive,but also lower the asphalt heating temperature for lib test (or construction), which further reduces the energy consumption and environmen- tal pollution. Using HMA as a control,the test results show these two kinds of asphalt mixtures have similar road performance, and the fatigue performance of Shell-finished WMA is more exeellent.
