- 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.
- 通过环氧树脂、SBS改性乳化沥青、SBS改性热沥青和H# 桥面防水材料等4种粘结层材料组合试件的剪切试验, 对影响排水性路面的行车荷载、温度和水等外部因素进行了研究和分析.试验结果表明, 温度升高会造成层间结合能力的降低, 层间剪切强度与温度之间的关系接近一条对数曲线.在实际路面中, 行车荷载作用中心区域下的剪切强度较其他部位要小.冻融和饱水等水损害都明显地降低了路面抗剪强度, 破坏了上中面层间的层间结合.荷载、温度和水等因素的作用会对层间结合状况产生一定的不利影响, 需要通过优选粘结层材料来提高排水性路面的耐久性.
