应力吸收层抵抗反射裂缝能力评价方法的研究

Research on evaluating method to the ability of resisting reflective cracking for stress absorbing layer

借鉴Superpave设计方法进行了应力吸收层混合料的设计,并采用冲击韧性指标对其抗裂性能进行评价,采用COOPER疲劳试验对其疲劳性能进行了验证,以促进应力吸收层的研究和应用。

This article designs the stress absorbing layer mixture according to the Superpave design theory, and evaluating the ability of resisting reflective cracking by impaetive tenacity, verifyed the fatigue properties by COOPER fatigue experiment, to aeee!erate the reference to the designers of gear box.
