摘　　要：拟定九种路面结构组合,采用有限元分析不同轴载及铣刨后旧路模量下路面结构动力学响应。建立Gumbel极值温度模型,提出基于重现期的沥青路面低温设防指标及计算方法,改进抗裂公式评价不同结构低温抗裂性。基于全寿命周期费用模型评价再生路面经济性。最后建立权重博弈论-模糊法评价模型评价不同路面结构综合性能,提出新疆地区再生路面合理结构方案:4 cm改性AC-13+6 cm改性AC-20+8 cm AC-25+14 cm再生层+20 cm水稳碎石。Nine pavement structure combinations are proposed,and the dynamic response of pavement structure under different axle load and milled old road modulus is analyzed by finite element method.The Gumbel extreme temperature model is established,the low-temperature fortification index and calculation method of asphalt pavement based on return period are proposed,and the crack resistance formula is improved to evaluate the low-temperature crack resistance of different structures.The economy of recycled pavement is evaluated based on the life cycle cost model.Finally,the weight game theory fuzzy method evaluation model is established to evaluate the comprehensive performance of different pavement structures,and the reasonable structure scheme of recycled pavement in Xinjiang is proposed as follows:4 cm modified AC-13+6 cm modified AC-20+8 cm AC-25+14 cm recycled layer+20 cm water stable gravel.
