技术简介

该技术采用溶剂萃取技术，利用溶剂相似相溶的原理，将废旧沥青路面材料中的沥青油溶解变成混合液，再将混合液中的溶剂蒸发回收，循环使用。得到两种产品：沥青油和砂石料。

Introduction

This line adopts solvent extraction technology. Asphalt oil in the waste asphalt pavement material isdissolved into a mixed solution based on the principle of mutual dissolution between solute and solvent in asimilar structure, and then the solvent in the mixed solution is evaporated for recycling. Two products, i.e.asphalt oil and sand & gravel, are obtained.
