摘要
以A级的70号沥青作为新沥青,在提取的废旧沥青中添加自制再生剂与新沥青形成再生沥青,重点分析了再生沥青的针入度、软化点指标,在进行多种实验方案对比后,指出在废旧沥青中掺合适当比例的再生剂,并且添加2倍于废旧沥青质量的新沥青所得的再生剂更具合理经济性,再生剂适宜比例为占总质量6%废机油、1.4%环氧树脂、4%聚丙烯树脂。
Taking the A grade No. 70 asphalt as the new asphalt, this paper formed recycled asphalt add homemade regeneration agent in the ex- traction of waste asphalt to new asphalt, emphatically analyzed the penetration, softening point index determination of recycled asphalt, after sev- eral experiments comparison, pointed out that recycled agent had more reasonable economy mixing appropriate proportion of recycled agent in waste asphalt, and adding 2 times waste asphalt quality new asphalt, the recycled agent suitable proportion accounted for 6% waste oil, 1.4% epoxy resin, 4% polypropylene resin of total mass.
