在路面标高不变的情况下,对旧路进行结构转换并实现其性能恢复。初步拟定面层结构参数,根据旧路标高和铣刨深度,确定冷再生基层结构厚度。根据AI沥青面层疲劳预估模型和重庆交通大学提出的冷再生半柔性基层疲劳寿命预估模型,提出了不同交通等级下的设计指标控制标准,并在有限元计算的基础上,得出了冷再生半柔性基层材料模量的参考范围。 In the case of the same elevation of the pavement, the structure of the old road conversion and to achieve its performance recovery. The initial formulation of surface structure parameters, according to the old road elevation and milling depth, to determine the cold regeneration of grass-roots structure thickness. According to the fatigue prediction model of AI asphalt surface and the prediction model of semi-flexible base fatigue life of cold regeneration proposed by Chongqing Jiaotong University, the design criteria control standards under different traffic levels are proposed. Based on the finite element calculation, Cold Regeneration of semi-flexible base material modulus reference range.
