温拌沥青混合料性能研究
|
摘要
目前,道路建设中的沥青路面基本上都采用传统的热拌沥青混合料HMA(Hot Mix Asphalt),然而HMA的应用会导致环境破坏、能源的大量消耗和人的生存圈缩小等负面影响。温拌沥青混合料WMA(Warm Mix Asphalt)这种新型环保节能产品可以通过一定的技术措施,降低沥青的粘度,从而沥青混合料可在相对较低的温度下进行拌和施工,同时保证其路用性能不低于HMA的沥青混合料技术,达到节能及环保的目的。
本文主要对掺加低熔点的添加剂H1和H2的温拌沥青混合料进行了深入研究。通过对沥青胶结料性能和沥青混合料路用性能的研究表明,掺入适量的H1和H2,可以分别通过降低沥青高温粘度和在一定温度下失水形成泡沫以增加和易性这两种形式来降低其混合料的拌和及压实温度,从而实现沥青混合料的温拌。温拌沥青混合料与热拌沥青混合料相比,掺加适量的H1可以显著改善沥青混合料的高温性能,提高沥青路面的抗车辙能力,但对低温性能及水稳定性影响较小;而适当掺量的H2对沥青混合料的高温性能、低温性能及水稳定性影响都不明显。
从社会效益、经济效益综合评价来看,在达到温拌效果同时,H1添加剂成本较高,适合夏季温度高、高温持续时间长、重载交通路段沥青混凝土施工;而H2添加剂可以显著降低成本,适用于低温条件下和高海拔地区沥青混合料的施工。
At present, the asphalt pavement in road construction mostly adopts the traditional material HMA (Hot Mix Asphalt). However the usage of HMA can causes environmental damage, excessive consumption of energy and shrink of living space for people.For these reasons, WMA (Warm Mix Asphalt) as a new energy-saving anenvironment- protecting product could force asphalt to be mixed and compacted in a comparatively low temperature by the means of reducing its viscosity with the help of certain techniques. Meanwhile, it could maintain its performance which dose not below that of HMA, and furthermore carried out the purpose of energy-saving and environment-protecting.
This paper studied the WMA with the H1 and H2.The results of performance on asphalt binding and asphalt mixutres stated that H1 could reduce asphalt's high temperature viscosity and H2 could form foamy strcture under certain temperature.Both of the two materials could low the mix and compaction temperature of the asphalt mixture. Compared with the HMA, WMA with the H1 improved high-temperature performance and anti-rut capability but had a little effect on low-temperature performance , water stability and WMA with the H2 efforts lack of all performance.
From social and economic benefit, the H1 is expensive and fit the construction of asphalt mixutres under high temperature and heavy traffic, and the H2 could reduce the cost and fit the construction under low temperature and high altitude locals.
