为研究SA与DAT分别对排水沥青混合料的路用性能影响。首先,采用马歇尔试验确定热拌排水沥青混合料的最佳配合比;其次,对掺加SA与DAT的混合料进行路用性能试验。试验表明：温拌排水沥青混合料击实温度可降为155℃;SA与DAT温拌剂对排水沥青混合料降温幅度相近,但是前者抗车辙性能明显优于后者;低温性能略低于后者;水稳定性两者相近。因此,温拌技术应用于排水沥青路面通过外掺温拌剂法是可以实现的,并且优先选用SA作温拌剂。由此提出了一种低碳环保的绿色筑路技术。

温拌沥青混合料在摊铺行业应用越来越多。尽管温拌沥青有许多优点,水稳定性是温拌沥青混合料潜在的不利因素之一,所以有必要在这一领域进行更多的研究,以提高温拌沥青性能。在研究中,熟石灰作为改善沥青混合料的水稳定性的抗剥落剂,用表面自由能法对集料和沥青之间的粘结性进行了分析。该实验采用了石灰岩和花岗岩两种类型的集料,并用asphamin作为温拌剂,熟石灰作为抗剥落剂。结果表明,熟石灰增加了沥青对集料的浸润性,提高了沥青和集料之间的附着力。添加消石灰的样品,沥青-集料与水-集料的表面自由能相差不大。这说明如果发生剥落则需要更多的能量,也就是消石灰提高了温拌沥青混合料的抗水损害性能。
Warm mix asphalt is increasingly adopted in paving industry. Although with many advantages, warm mix asphalt has the disadvantage of low moisture susceptibility. So more studies are necessary to improve warm mix asphalt performance. In the study, hydrated lime is adopted as anti-stripping a-gents to improve water stability of asphalt and the cohesiveness between aggregate and asphalt is analyzed with surface free energy method. The two aggre-gates of limestone and granite are adopted in the study with asphamin as warm agent and hydrated lime as anti-stripping agents. The results show that hy-drated lime enhances the asphalt wet ability to aggregate and improves the adhesiveness between asphalt and aggregate. Based on the sample with hydrated lime, the surface free energy of asphalt, aggregate and water and aggregate differs little, which means that more energy is needed for stripping, that is to say, hydrated lime can improve waterproof performance of warm mix asphalt.
