Abstract:

Through the shear tests on composite specimens using four different kinds of tack coat material(epoxy resin, SBS modified emulsified asphalt, SBS modified asphalt and H# bridge waterproof material), the bond condition between layers of porous asphalt pavement under traffic load, temperature variation and moisture situation is evaluated.The test results show that the bond strength decreases with the rise in temperature, and the relationship between shear strength and temperature can be expressed by a logarithm curve at a high reliability.Under the action of traffic load, the value of shear strength of the mixture right under the centre of the wheel track is smaller than that of other parts of the pavement.It is also found that some effects concerning moisture have comparative effects on the bonding of the two layers.Given all the results achieved during the study, it will be quite rewarding to make rational comparisons during selecting the sound type of tack coat.
