摘要
针对泡沫沥青冷再生路面合理结构厚度问题,拟定了27种典型的冷再生路面厚度组合,运用BISAR3.0软件分析了不同厚度组合下的路表弯沉、冷再生层承载能力和疲劳寿命.结合工程实践和我国交通等级的规定,提出了不同交通等级下泡沫沥青冷再生路面的合理结构厚度.
According to the promble of reasonable structure thickness of cold-recycled pavement with foamed bitumen,the paper studied out 27 kinds of typical cold-recycled pavemen thickness combination.The surface deflection、 bearing capacity and fatigue life of different thickness combination were computed with BISAR3.0.Combination of engineering practice and the provisions of our traffic levels,the paper put forward the reasonable structure thickness of cold-recycled pavement with foamed bitumen under different traffic levels,in order to provide a reference for the practical engineering application
