Evaluation of Shear Strength on Pavement Layers by Use Tack Materials
Pavement bonding associates with shear strength which depends on different tack coat materials and temperature. The higher temperature has, the lower shear strength is; and increasing the application rate does not significantly improve the shear strength. The test results show that the shear strength decreases with an increase in temperatures has the maximum value at optimum application rate (OAR) and emulsion asphalt used has higher shear strength than that of cutback asphalt. The tack materials and temperature are significantly effective the shear strength, in accordance with the statistic of two-way analysis of variance (ANOVA) test.
