摘要
先进的温拌沥青技术可以使温拌沥青混合料达到热拌沥青混合料的性能。本文通过大量的室内试验,并对比了掺加RH温拌剂前后沥青及沥青混合料性能指标的变化。试验测试结果表明:在沥青中加入RH温拌剂后,沥青的高温黏度显著降低,130℃的4%RH+SBS改性沥青混合料与160℃的SBS改性沥青混合料的各项性能指标相当。
Advanced warm mix asphalt technology allows warm,mix asphalt to reach the performance of hot mixasphalt.This paper,compared the performance index changes of asphalt and asphalt mixture before and after add-ing RH warm mix agent by a large number of laboratory tests. Experimental results showed that,after adding RHwarm mix agent in asphalt,high-temperature viscosity of asphalt significantly reduced,the performance index isquite similar between 4%RH ＋ SBS modified asphalt mixture at 130℃ and SBS modified asphalt mixtureat 160℃.
