沥青路面要保证具有一定的使用年限,而不会在较短时间内出现路面大修,除考虑路面结构上设计合理之外还要保证面混合料具有耐久性。耐久性好坏使用抗老化性能、耐疲劳性能、水稳定性和抗滑特性几方面评价。而其中的抗老化性能评价较复杂,且沥青老化的影响因素较多。从影响沥青老化的各个阶段出发,合理分析不同因素的影响,并列举出现阶段的试验评价方法,总结试验方法的差异。
Asphalt pavement to ensure that has a useful life, but not in a relatively short period of time pavement overhaul, in addition to considering the road surface structure design is reasonable but also to ensure the durability of the mixture. Durability is good or bad use of anti-aging properties, fatigue resistance, water stability and anti-slip properties of several aspects of evaluation. Among them, the evaluation of anti-aging performance is more complicated, and there are many influencing factors of asphalt aging. Starting from the various stages affecting the aging of asphalt, the influence of different factors is reasonably analyzed. The method of test evaluation at the present stage is listed, and the differences of test methods are summarized.
