| 摘 要： | 针对使用中存在的路基回弹模量衰减问题,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设计年限内路基回弹模量衰减对公路沥青路面厚度设计的影响.实例计算结果表明：当路基回弹模量衰减超过20%时,所设计的沥青路面厚度已小于使用要求的限度.研究成果可供考虑路基回弹模量衰减的公路沥青路面厚度设计时参考.

| Abstract: | According to the problem of roadbed resilience modulus attenuation, the influence of roadbed resilience modulus attenuation in design 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 the designed asphalt pavement thickness is less than requirement thickness limits when roadbed modulus attenuation is more than 20%. The research can provide a reference for the asphalt pavement thickness design under considering roadbed resilience modulus attenuation. |
