Abstract This research was conducted to investigate the shear strength at the interface between polymer concrete and asphalt concrete with geotextile as reinforcement at the interface of these two types of concrete. The samples were tested for the parameters of different surface conditions [rough and smooth], curing types [room and thermal curing], temperature effect and the impact of geotextile as reinforcement. To investigate the correlation between these parameters, four different testing conditions were implemented. The results showed a significant improvement of shear strength for rough surface sample as compared to smooth surface sample. Moreover, samples cured in oven had lower shear strength as compared to samples cured in room condition. Besides that, high temperature has an adverse impact on the shear strength at the interface between polymer concrete and asphalt concrete due to the weakening of asphalt concrete at high temperature. As for samples reinforced with geotextile, the shear strength resistance was better as compared to unreinforced samples. Through visual observation, the types of failure under all testing conditions were mixed failure mode.

土工布增强复合路面界面抗剪强度评价

摘要 本研究旨在研究聚合物混凝土和沥青混凝土界面处的剪切强度，土工布作为这两种混凝土界面处的钢筋。对样品进行了不同表面条件[粗糙和光滑]、固化类型[室温固化和热固化]、温度效应和土工布作为增强材料的影响的参数测试。为了研究这些参数之间的相关性，实施了四种不同的测试条件。结果表明，与光滑表面样品相比，粗糙表面样品的剪切强度显着提高。此外，与在室温条件下固化的样品相比，在烘箱中固化的样品具有较低的剪切强度。除此之外，由于沥青混凝土在高温下弱化，高温对聚合物混凝土和沥青混凝土界面处的剪切强度有不利影响。对于用土工布增强的样品，与未增强的样品相比，抗剪切强度更好。通过目视观察，所有测试条件下的失效类型均为混合失效模式。
