摘要: 提出了一种新型的冷再生沥青混合料-水性环氧树脂改性乳化沥青冷再生沥青混合料,首次使用环氧乳化沥青应用于冷再生沥青混合料中。通过掺加0%、10%、20%和30%的环氧树脂改性乳化沥青对90%与70%RAP(废旧沥青路面回收材料)掺量的AC-20冷再生沥青混合料进行配合比设计试验与使用性能验证。结果表明:适当掺量的环氧树脂改性乳化沥青可使冷再生沥青混合料具有更好的使用性能,RAP有效利用率得到进一步提高。

Abstract: A new type of cold recycled asphalt mixture-Waterborne Epoxy Resin modified emulsified asphalt cold recycled asphalt mixture was proposed and it is the first to use epoxy emulsified asphalt in cold recycled asphalt mixture. The mix design test and the performance verification of the AC-20 cold recycled asphalt mixture of 90% and 70% RAP( Reclaimed Asphalt Pavement) content were conducted by adding the epoxy resin of 0%,10%,20% and 30% modified asphalt emulsion. The results show that the epoxy resin of proper dosage modified emulsified asphalt cold recycled asphalt mixture can have better performance and RAP effective utilization can be further improved.
