Study on the Mechanical Properties of Tack Coat between Asphalt Layers by Interlaminar Shear Tests
In order to study the mechanical properties of tack coat for asphalt pavement, the interlaminar shear test is introduced. Under the variety condition, the direct shear test is executed. The shear strengths are fitted by linear regression theory and the Mohr-Coulomb parameters are calculated. The results show that as pavement adhesive layer materials, SBS modified emulsified asphalt performance than the ordinary emulsified asphalt, the best dosage is 0.4 kg/m2, and SBS modified emulsified asphalt adhesive layer material immersion strength increased nearly 20%. When the interface material adds the cement, the strength will also increase and indicate good shear strength. With the normal stress increased, the shear strengths are increased. The shear strengths with normal stress are affected significantly by the interfacial friction, roughness of interface and normal stress.
