沥青路面热再生技术的设计及施工要点

Design and Construction Essentials for Asphalt Pavement Thermal Regeneration Technique

总结了沥青路面热再生技术的原理、工艺类型和主要特征,需要根据路面病害程度和修复要求确定现场的热再生工艺。分析了开展沥青路面热再生技术的设计要点,不仅需要对旧有道路进行性能评测,还需要优化选用外掺材料和配合比,最后探讨了路面再生技术的现场施工要点和质量控制方法。

The mechanism, technological type and main features of thermal regeneration technique of asphalt pavement are summarized. The related thermal regeneration technique is determined by the disease degree and repair requirement of pavement. The design essentials for the thermal regeneration technique of asphalt pavement are analyzed. It is not only to evaluate the materials properties of the severed asphalt pavement, but also to optimize the external mixing materials and mix proportion. Finally, the field construction essential and the quality control method of pavement regeneration technique are discussed.
