| 摘 要： | 根据AC10型细粒式沥青混凝土应力吸收层的设计，提出基于路用性能均衡的应力吸收层的设计方法。即采用最佳紧密状态油石比为下限，谢伦堡析漏试验析漏损失率拐点油石比为上限，并根据路用性能最优确定应力吸收层最佳油石比。通过广西一高速公路实体工程验证，取得了良好的应用效果。

| Abstract: | According to the design of AC10 fined grained asphalt concrete used as stress absorbing layer,this paper proposes the related design method based on equilibrium of pavement performance.This method adopts the asphalt-aggregate ratio under closest compact condition as lower limit and that at the inflexion of run-off loss ratio in Schellenberg Binder Drainage Test as upper limit to finally determine the optimum asphalt-aggregate ratio according to the optimum pavement performance.Through the verification of a substantial highway project in Guangxi province,it achieves good application result. |
