摘要
根据现代胶体化学的经典理论,分析了沥青的老化机理及废旧沥青的再生机理;通过不同老化周期沥青的性能重塑试验,对新型的沥青再生剂重塑废旧沥青混合料性能作出了分析与评价。试验结果表明:新型沥青再生剂有效地再生了老化沥青,重塑了老化沥青的路用性能。
Based on the classical theory of modern colloid chemistry, the mechanism of aging and regeneration of aged asphalt are analyzed. Through recovery tests on asphalt aged for different periods, the performance of aged asphalt recovered with a new type of asphalt regenerant is analyzed and evaluated. The results indicate that the new asphalt regenerant regenerates aged asphalt and recover the road performance of aged asphalt mixture effectively.
