摘要
利用已建立的全寿命沥青路面结构行为方程和寿命周期费用分析模型 ,在考虑不同的设计条件、不同的经济优化目标和分析期内不同的罩面措施组合的基础上 ,采用现值法进行沥青路面结构厚度优化设计。
The outcomes of optimization design of asphalt pavement structural thickness based on life-cycle pavement performance are influenced by many factors.The paper brifely introduces the concept of whole life-cycle cost based design method,whole life-cycle asphalt pavement structural behavior equations and life cycle cost analysis models and stresses on the influence of different overlay thickness combination within analysis period.Based on the whole life-cycle asphalt pavement structural behavior equations and life cycle cost analysis models, the authors optimize asphalt pavement structural thickness using present value on the basis of considering different design conditions, different economy criteria and different overlay thickness combination within analysis period and illustrate the influence of different overlay thickness combination on the optimum thickness of pavement structure within analysis period.
