Detection device and method used for rut resistance performance of entity pavement

Abstract

The invention provides a detection device and method used for the rut resistance performance of an entity pavement. The method comprises the following steps: firstly, drilling two core sample test pieces of a cylindrical structure through a core boring sampler, and respectively cutting and trimming two core samples into two sections of test pieces of the same thickness according to the shape and the size of a test mode installation hole, wherein a shape spliced by the two test pieces is the same with the structure of the test mode installation hole; then, according to the thickness of the above cut and trimmed core sample test piece, selecting a blockage plate, putting the two sections of test pieces into a test mode, and installing the test mode on a test piece table to be tested. The method puts forward a reasonable rut test method capable of overcoming the difficulty in plate-type test piece sampling, the core sample is obtained through a core drilling sampling way, the detection device and method can be used for detecting the rut resistance performance of the entity pavement, indoor design and field detection can be organically combined, and therefore, the detection of the rut resistance performance of the entity pavement cannot be ignored. Compared with a plate-type rut test method, the method is easy in sampling and convenient in operation.

Description

technical field [0001] The invention belongs to the technical field of detection of anti-rutting performance of asphalt mixture, and in particular relates to a detection device and method for the anti-rutting performance of a solid road surface. Background technique [0002] At present, my country's "Test Regulations for Asphalt and Asphalt Mixtures in Highway Engineering" stipulates that asphalt mixture plate specimens should be used to measure its high-temperature anti-rutting performance to test the rationality of asphalt mixture design ratios, and the regulations point out that it can be used on asphalt pavement The dynamic stability of the upper-cut plate-shaped specimen is measured on the national standard rutting tester, so as to reflect the anti-rutting performance of the pavement structural layer. However, in actual engineering, it is difficult to cut and sample plate-shaped specimens on the solid pavement, even if the sampling is successful, it will cause great dama...
