热拌沥青混合料:21世纪展望与挑战——材料与混合料设计

HMA: Outlook and Challenge in the 21st Century -Materials and Mixture Design

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 。

Being a part of 'HMA outlook and challenge in the 21st century','materials and mixture design'described the ongoing and future focal research programs in the area of design system methodology,hot mix asphalt,binders,aggregates,etc These porograms involved performance related specifications,mechanism prediction matrix,water sensitivity and durability testing,application of Superpave mixtures,waste materials,mixing and compacting temperature,thicker and stiffer asphalt layer,modified asphalt,etc which were valuable to home highway and petroleum asphalt industry
