常温再生沥青混合料及其制备方法
摘要：
一种常温再生沥青混合料及其制作方法，属于沥青领域。常温再生沥青混合料，主要由按照重量百分比计的以下组分制作而成：再生沥青1.4～1.8％；集料38.2～38.6％；废旧沥青混合料60～60.4％。其中，再生沥青是由甲基苯乙烯类再生剂改性的基质沥青。上述常温再生沥青混合料可通过如下方法制作而成：基质沥青与甲基苯乙烯类再生剂在90～130℃条件下拌合并保温，得到再生沥青。再生沥青与集料、废旧沥青混合料在120～140℃条件下拌合，得到所述常温再生沥青混合料。本发明提供的常温再生沥青混合料实现了在相对较低的温度下对废旧沥青进行再生的目的，并且具有较好的路用性能和环保、经济效益。
摘要（英）：

The invention provides a normal temperature recycled asphalt mixture and a preparation method thereof and belongs to the asphalt field. The normal temperature recycled asphalt mixture is prepared from the components, by weight, of 1.4%-1.8% of recycled asphalt, 38.2%-38.6% of aggregate and 60%-60.4% of waste asphalt mixture. The recycled asphalt is alpha methyl styrene class regenerant modified matrix asphalt. The normal temperature recycled asphalt mixture is prepared with the following method: the matrix asphalt and the alpha methyl styrene class regenerant are blended at the temperature of 90 DEG C to 130 DGE C, heat preservation is performed, and the recycled asphalt is obtained; the recycled asphalt, the aggregate and the waste asphalt mixture are blended at the temperature of 120 DEG C to 140 DEG C, and the normal temperature recycled asphalt mixture is obtained. According to the normal temperature recycled asphalt mixture, the purpose for recycling waste asphalt at relative lower temperature is realized, and the mixture has better pavement performance and environment protection and economy benefits.
