一种沥青路面层间粘结力的测试方法
摘要：
本发明涉及一种沥青路面层间粘结力的测试方法，其包括如下步骤：制备试件：将下层水泥混凝土试件通过粘层油与上层的沥青混凝土粘结；(2)安装试件，将待测试的试件放置于下夹具中，缓缓地下降压头，继续下降压头，使得上下夹具贴紧，将上下夹具分别与试件固定紧；(3)开始测试，开启压力机，调整好速率，开始进行拉拔测试，显示器上力值和位移开始变化，当把试件拉开之后，力值达到峰值，记录。本沥青路面层间粘结力的测试方法，能够真实模拟沥青路面的竖向载荷载荷，获取粘结力粘结力参数，便于层间材料粘合性能评价。
摘要（英）：

The invention relates to a testing method of interlayer bonding power of an asphalt pavement. The testing method comprises the following steps: preparing a test piece: bonding a lower-layer cement concrete test piece with upper-layer asphalt concrete through bonding layer oil; (2) mounting the test piece: putting a test piece to be tested into a lower clamp and slowly lowering a pressing head; continually lowering the pressing head so as to tightly stick an upper mold and the lower mold; and tightly fixing the upper and lower clamps with the test piece respectively; (3) starting to test: starting a pressure machine and adjusting the speed; starting to carry out a pulling test to enable a force value and displacement on a display device to be changed; and when the test piece is pulled to be opened and the force value reaching a peak valve, recording. According to the testing method of the interlayer bonding power of the asphalt pavement, a vertical load of the asphalt pavement can be really simulated and bonding power parameters are obtained; and evaluation of bonding performances of an interlayer material is convenient to realize.
