摘　　要：随着现在科技的不断发展,人们对于我们的生活质量也有所提升,当然,好的交通才会有好的物质来源,文章就公路沥青路面层间粘接结构的性能进行进一步的研究,首先,我们会在实验室内对模拟的公路沥青路面层间粘接结构的性能进行剪切和拉拔的实验,并用剪切强度和拉伸强度来作为评价的指标,从而来分析这两个因素对公路沥青路面层间粘接性能的作用,就我们在实验室所做的实验,可得乳化沥青是存在着最佳的用量,这就使得在一定的层面上就可以来降低其层面上的粘接性,并随之可能发生的是随着层阍污染物的的上升,层间的剪切强度也随之减少,除此之外,这两种性能会随着温度的升高,从而各自和温度呈现线性关系,而且,层间的剪切强度和拉伸强度就有着较为好的相关性,下文就对此就分三个方面来进行阐述:实验·剪切强度·拉伸强度。With the continuous development of science and technology,people's quality of life has also been improved.Of course,good traffic will have a good material source.This paper further studies the performance of the interlayer bond structure of highway asphalt pavement.First,we will perform shearing and drawing experiments on the performance of the simulated asphalt pavement interlayer bonding structure in the laboratory.The performance of bonding structure is tested by shearing and drawing,and the shearing strength and tensile strength are used as evaluation indexes to analyze the effect of these two factors on the interlayer bonding performance of highway asphalt pavement.According to our experiments in the laboratory,it is possible to obtain the optimum amount of emulsified asphalt,which makes it possible to reduce the adhesion at the level on a certain level.In addition,the shear strength between layers decreases with the increase of the contaminants.In addition,these two properties will increase with the increase of temperature,thus showing a linear relationship with temperature.Moreover,the shear strength between layers and the shear strength between layers have a good correlation.The following is a three-part explanation:experimental,shear strength and tensile strength.
