沥青路面热再生技术是将不能满足使用要求的旧沥青路面沥青混合料RAP(Recycled Asphalt Pavement)经过一定的加工和处理,包括对旧沥青路面进行翻挖、破碎、筛分,再和新集料、新沥青、再生剂(必要时)重新混合,变成可以达到技术标准要求的混合料以后,重新铺筑为新的路面。热再生沥青混合料的路用性能易受更多因素的影响,RAP中的老化沥青向新集料的转移程度及均匀度也是重要的影响因素之一。以下主要对其热再生机理进行探讨。
Asphalt Pavement Thermal Recycling Technology is to process and process RAP (Recycled Asphalt Pavement), which can not meet the requirements of use, including digging, crushing and sieving the old asphalt pavement, and then with the new aggregate , New asphalt, regenerant (if necessary) remix, into a mixture of materials to meet the requirements of technical standards, re-paved the new road. The road performance of hot recycled asphalt mixture is more affected by more factors, and the transfer degree and uniformity of the aged asphalt in the RAP to new aggregate is also one of the important factors. The following main discussion of its thermal regeneration mechanism.
