Investigation into Influence Factors on Shear Properties between Layers of Asphalt Pavement
The failures of bonding between pavement layers are believed to be associated with shoving and may cause other distresses. The objective of this study is to investigate the influence factors on shear strength, including types of tack coat, application rate, upper layer type, test temperature, as well as interface contamination. A test device which is capable of applying normal stress is employed to evaluate the shear properties between layers. Results showed that Novechip® performed the best among all the upper layers. Self-developed polymer modified emulsified asphalt performed best among all the tack coats. The interface contamination between layers significantly decreased the shear strength. Test temperature is proven to be the most significant factors that affect the shear strength. The results presented in this study may potentially provide meaningful information on the selection and installation of tack coat between pavement layers.
