摘　　要：针对使用中存在的沥青路面材料抗压回弹模量衰减问题,应用《公路沥青路面设计规范》(JTG D50-2006)和弹性多层体系理论研究了使用年限内沥青材料抗压回弹模量衰减对公路沥青路面路表回弹弯沉值的影响.实例计算表明:当沥青路面材料抗压回弹模量以3种常见形式衰减时,路表回弹弯沉值分别增加了45.93%,59.79%和51.08%,导致所设计公路沥青路面厚度难以满足使用要求.研究结果可供考虑沥青路面材料抗压回弹模量衰减的公路沥青路面厚度设计时借鉴.According to the problem of asphalt pavement material resist resilience modulus attenuation,the influence of asphalt pavement material resist resilience modulus attenuation in use period on highway asphalt pavement thickness was researched by specifications for design of highway asphalt pavement(JTG D50-2006) and elastic multi-layer system theory.Example results show that road surface calculation deflections are increased by 45.93%,59.79% and 51.08% so that designed asphalt pavement thickness cann't meet the requirements.The research can provide a reference for the asphalt pavement thickness design under considering asphalt material resist resilience modulus attenuation.
