Problems solved by technology
It can be seen from the above that the qualitative analysis method is relatively simple to operate, but it cannot quantify the value, and it is difficult to accurately judge the impact resistance of the material; the quantitative analysis method has more accurate data, but the instrument operation is more complicated, and both methods have certain limitations.
[0003] After the impact of the existing method, it is necessary to manually check and detect it. It is believed that there is a large error in the detection lamp, and at the same time, the change of material adhesion after the impact cannot be detected, etc. It is necessary to design a test device for the impact resistance of road materials and test methods

The invention provides a device and method for testing the impact resistance of a road material, and belongs to the technical field of impact resistance testing of road materials.The device comprises a base, a base layer, a material layer, a crack detection device, an adsorption force detection device, an impact direction barrel, an acceleration device and an iron ball storage barrel, the base layer is arranged on the base, the material layer is arranged on the base layer, and the adsorption force detection device is arranged on the material layer; the crack detection device and the adsorption force detection device are arranged at the two ends of the material layer, and the crack detection device is movably arranged. According to the invention, tests with different impact points and impact directions can be realized by changing the direction of the impact direction cylinder according to the impact direction needing to be tested, meanwhile, the tests are completely automated, after impact is completed, cracks and adsorption force are automatically detected, a test material layer is detected more comprehensively, and the device has the advantages of uniform structure detection standard, high detection efficiency and the like. Manual participation in detection is not needed, and the detection speed is high and is more than three times that of a traditional detection method.
Description
technical field [0001] The invention relates to the technical field of impact resistance performance testing of road materials, in particular to a testing device and a testing method for impact resistance performance of road materials. Background technique [0002] Road materials need to have good road performance. When testing road performance, it is necessary to not only systematically analyze its short-term performance indicators, but also pay attention to its long-term performance indicators. Impact resistance is a relatively important technical index in the long-term performance of road materials. At this stage, there are mainly two methods for testing it. One is qualitative analysis method, in which a steel ball of a certain quality is dropped freely onto the material to be tested. The other is the quantitative analysis method, which mainly relies on the drop hammer or pendulum impact instrument to obtain a certain impact strength value, so as to judge the material res...
