基于PAV和RTFOT法的冷拌沥青混合料性能研究

Research on Performance of Cold-mix Asphalt Mixture Based on PAV and RTFOT Method

文章基于冷拌沥青混合料的分类、特性及要求,采用压力老化试验(PAV)和旋转薄膜烘箱试验(RTFOT)研究了溶化型与乳化型两种冷拌沥青混合料的性能,制定了冷拌沥青混合料的性能评价方法和指标,建立了冷拌冷铺沥青混合料评价体系。

Based on the classification, characteristics and requirements of cold-mix asphalt mixture,this article studied the properties of dissolved and emulsified cold-mix asphalt mixtures by pressure aging test（PAV）and rotating thin-film oven test（RTFOT）, developed the performance assessing methods and indicators for cold-mix asphalt mixture,and established the evaluation system for cold-mix asphalt pavement.
