摘　　要：结合贵州某公路热再生维修工程,根据旧沥青路面材料(RAP)样品所测定的沥青含量和矿料级配结果,确定在旧沥青路面材料(RAP)中添加再生剂并掺加新拌AC—13沥青混凝土来进行就地热再生,得出再生剂掺量为3%、占总料比例为10%。经验证,新拌AC—13沥青混凝土不仅能满足热再生性能要求,而且能使再生沥青混合料各项技术指标满足规范要求。Combined with the thermal regeneration asphalt and gradation results measured in the sample of of one highway in Guizhou, according to the content of old asphalt road surface material（RAP）, the geothermal regeneration method of adding regenerant and new AC--13 asphalt mixture in old asphalt pavement materials is determined. The regenerant dosage is 3% and it takes 10% in total material. It is proved that fresh AC-13 asphalt concrete can not only meet the performance requirements of thermal regeneration, but also make the technical indicators of recycled asphalt mixture meet the requirements of specification.
