Embodiment 1
[0036] Present embodiment relates to a kind of measurement method of cohesive force between ice-asphalt pavement, such as figure 2 with image 3 Shown: Include the following steps:
[0037] The first step is to use hydrophilic quartz sand cement mortar to make the spindle 1 used in the test, with a molding height of 68mm and a diameter of 101mm, and connect the spindle to the screw rod of the XH-40 concrete strength puller of Beijing Tiandi Xinghuo Technology Development Co., Ltd. 2 Pre-fixed in cement mortar during molding, with a pre-embedded depth of 50mm;
[0038] In the second step, the polyester felt 4 with a circular metal plate 3 with a diameter of 101mm is combined with the spindle through epoxy resin and curing agent. The thickness of the polyester felt is 3mm, and the width around it is 15mm and four 5mm are reserved. The fixing metal ring 5 of the screw hole and the M5 screw 6 of 20mm are fixed on the spindle 1;
[0039] The third step is to determine four circ...
Embodiment 2
[0046] Present embodiment relates to a kind of measurement method of cohesive force between ice-asphalt pavement, such as figure 2 with image 3 Shown: Include the following steps:
[0047] Except that the third step AC-5 is replaced by AC-13 rutting plate, other steps are the same as in embodiment 1. Table 1 compares prior art with test result of the present invention:
[0048] Table 1
[0049]
[0050]
[0051] It can be seen from Table 1 that the measurement results of the prior art are more discrete, and the measurement results of the present invention are more accurate, real and stable. Depend on Figure 4 It can be seen from the figure that the area of the water film in the prior art is inconsistent, resulting in uncontrollable thickness of the ice layer, and more ice remains on the surface of the specimen. These factors will inevitably lead to large errors in measurement results and unstable data. The measurement method of the present invention can ensure...
