Strata应力吸收层在旧路改造中的应用

Application of Strata Stress Absorbing Layer in Reconstruction of Old Roads

摘要:

随着我国经济的高速发展,现状旧水泥混凝土路面已逐渐不能满足使用、舒适、美观及生态要求,亟需对旧水泥混凝土路面进行“白改黑”的技术改造。该文结合了江西省南昌县芳湖路改造工程,为最大程度减少罩面后产生的反射裂缝病害,采用了Strata应力吸收层+沥青混凝土的加铺改造技术,通过对加铺方案的甄选比对、材料性能分析及施工验收措施,并在施工过程中及竣工通车后持续跟踪观测,结果验证了该材料在防反射裂缝性能方面,较其它加铺技术有更大的优势,为其广泛应用提供了参考依据。

Abstract:

In the reconstruction project of Fanghu Road in Nanchang County of Jiangxi Province, in order to minimize the reflective crack disease after overlay, the overlay reconstruction technology of Strata stress absorption layer + asphalt concrete is adopted. Through the selection and comparison of overlay schemes, the material performance analysis and construction measures, it is verified that this material has greater advantages in anti-reflective crack performance than the other overlay technologies, which provides a reference basis for its wide application.
