不同类型温拌剂对沥青胶结料指标及混合料性能影响研究

Study on the Influence of Different Warm Agents on Asphalt Binder Index and Mixture Performance

摘要: 传统的热拌沥青混合料施工温度高，加热各种材料需耗费大量能源，对环境造成污染的同时也违背了节能减排的理念。本文选用国内较为常见的两种不同类型温拌剂，分别制备基质与改性温拌沥青胶结料，通过温拌沥青性能指标试验结果，对其降温和降粘机理进行分析，确定温拌剂的最佳掺量。进行了温拌沥青混合料设计，确定不同温拌剂的成型温度，并进行了温拌沥青混合料的路用性能研究。

Abstract: Traditional hot mix asphalt mixture construction temperature is high, heating all kinds of materials need to consume a lot of energy, causing environmental pollution, but also against the concept of energy conservation and emission reduction. In this paper, two different types of warm agents are used in China to prepare matrix and modified warm mix asphalt binder respectively. Through the performance index test results of warm mix asphalt, the cooling and viscosity reduction mechanism is analyzed to determine the optimal amount of warm mix. The design of warm mix asphalt mixture was carried out, the forming temperature of different warm mix was determined, and the pavement performance of warm mix asphalt mixture was studied.
