针对材料与混合料设计 ,展望了 2 1世纪热拌沥青工业界面临的挑战与机遇 ,论述了设计系统方法、热拌沥青混合料、胶结料、集料等方面正在进行今后将重点进行研究解决的问题 ,如与性能有关的规范、力学性能预测模型、水敏感性和耐久性试验、Superpave混合料使用、废料、拌和与压实温度、更厚更稠的沥青层、改性沥青等 ,这些对我国道路和沥青工业界均有一定的参考价值 In view of the design of materials and mixtures, the challenges and opportunities faced by the hot asphalt industry in the 21st century are forecasted. The design system methods, hot mix asphalt, cementitious materials and aggregates are discussed in the future. Issues such as performance-related specifications, mechanical property prediction models, water sensitivity and durability tests, Superpave mix use, scrap, blending and compaction temperatures, thicker, thicker bitumen layers, modified bitumen, etc. These It has certain reference value to our country road and asphalt industry
