高速公路沥青路面就地热再生技术与经济效益分析

摘要

为了更好地了解与推广沥青路面就地热再生技术,对高速公路沥青路面就地热再生技术特征与经济效益进行分析,提出沥青再生方法和最佳级配确定方法,并给出沥青路面就地热再生施工温度范围及施工质量检验方法.实践证明,采用沥青路面就地热再生技术进行路面维修可节省成本,节约资源与能源,且有利于环境保护.%In order to better understand and promote the asphalt pavement on-site thermal regeneration technology, the authors have analyzed asphalt pavement on - site thermal regeneration technology characteristics and economic benefits. This paper put forward method of asphalt regeneration and the method of determining the optimum gradation,and given the temperature range and the construction quality test method of asphalt pavement on-site thermal regeneration. Practice has proved that the use of asphalt pavement on-site thermal regeneration technology for road maintenance can save costs,save resources and energy,and is conducive to environmental protection.
