摘要
温拌沥青具有低能耗、环保、施工便捷等优点,是我国道路工程热拌沥青技术的良好改善和补充。分别从沥青混合料的材料特性、沥青面层结构性能及其施工性能等三个方面,分析总结了高速公路路面用温拌沥青混合料的基本特征,研究说明:施工温度要求低、能耗少和粉尘、废弃污染少是高速公路路面用温拌沥青的最大优势。提出了温拌技术在道路工程的主要应用前景以及存在的缺点和问题,说明建立设计和评估的综合评价体系,是温拌沥青广泛推广的重要基础。
The warm mixed asphalt has the advantages of low energy consumption, environmental protection and convenient construction, and is the good improvement and supplement of road engineering hot mixed asphalt technology in China. The article analyzes and summarizes the basic character of the warm mixed asphalt mixture used for expressway pavement from three aspects of the material character of asphalt mixture,the structural performance of asphalt surface and its construction performance. The study illustrates that thelow construction temperature, less energy consumption, less dust and less waste pollution are the biggest advantage of warm mixed asphalt used for the expressway pavement. The article puts forward the main application prospect of warm mixing technology in the road engineering and the existing problems. The establishment of the comprehensive design and evaluation system is the important base to widely popularize the warm mixed asphalt.
