摘要
粘层是路面结构的重要组成部分,粘层的抗剪强度与粘层油的用量和面层级配有密切的关系。文章选用了4种面层材料进行试验,研究不同面层级配类型以及粘层油撒布量对粘层强度的影响。试验结果表明:不同级配面层间的粘层油存在最佳撒布量,在最佳撒布量时粘层的抗剪强度达到最大。
Tack coat is an important part of asphalt pavement structure,the shear strength of tack coat has close realtion with the comsumption of tack oil and the gradation type of sur - face course.The article selects the four gradation types of surface to study hew the tack coat strength were affected by the different gradation types and the consumption of tack coat oil. The test result shews that the tack coat between different gradation types of surface course has the optimum consumption; when the consumption is optimum, the shear strength will reach the maximum.
