摘　　要：粘接强度是评价防水涂料与基层粘结性能的重要指标。研究讨论了不同标准、不同制样方法对高聚物改性沥青基层处理剂粘结强度指标测试结果的影响,得到最优的制样和测试方法,为低固含量、低黏度、具有优异流动性的涂料产品(类似高聚物改性沥青基层处理剂产品)采用“8”字水泥砂浆块测试粘结强度指标(GB/T 16777—2008标准中的B法)的方法提供一定的理论依据。Bonding strength is an important index requirement for evaluating the bonding performance between waterproof coating and base course.This paper discusses the influence of different standards and sam-ple preparation methods on the test results of bond strength index of polymer modified asphalt base course treatment agent.It provides a certain theoretical basis for coating products with low solid content,low viscosity and good fluidity(similar to polymer modified asphalt base treatment agent products)to test the bond strength index with“8”cement mortar block(method B in GB/T 16777-2008 standard).
