摘要:

通过室内拉拔试验和剪切试验，对比研究了不同界面处理方式对刚柔复合式路面界面层抗剪强度、黏结强度的影响，并依托工程实践对新型高碳糖露石剂的应用效果进行了验证.结果表明：与光面、拉毛、喷砂等传统界面处理方式相比，应用新型高碳糖露石剂处理水泥混凝土板表面能显著提高界面层的抗剪强度和黏结强度，与现有露石剂使用效果相当，但相比之下，新型高碳糖露石剂可降低约93%的成本，经济效益显著.

Abstract:

Shear strength and bond strength of interfacial layer with different interface treatments were studied through laboratory tests and the effect of high carbon sugar aggregate exposing solvent was examined in conjunction with the practical engineering. The results show that compared with the other interface treatments of smooth, brushed, and sandblasted, the application of high carbon sugar aggregate exposing solvent could significantly increase the shear strength and bond strength of interfacial layer. Compared with the existing aggregate exposing solvent, the effect of high carbon sugar aggregate exposing solvent is similar but the costs can be reduced by approximately 93% which also has better social and economic benefits.
