Asphalt adhesive force testing device for road construction

Abstract

The invention relates to a road construction asphalt adhesive force testing device, which comprises a supporting module which can rotate or rotate to a position required for fixation and is used for supporting a testing sample plate laid on the surface of the supporting module, and the appearance fitting track of the testing sample plate and the supporting module is a curved surface; and the rolling module is used for rolling the test sample plate laid on the supporting module.

Description

technical field [0001] The invention relates to the technical field of road construction asphalt adhesion testing devices, in particular to a road construction asphalt adhesion testing device. Background technique [0002] At present, asphalt is used in road and bridge construction, because asphalt has good insulation, heat insulation and moisture-proof, seepage-proof, waterproof, anti-corrosion, anti-rust and other properties, because asphalt is attached to the roadbed or On the bridge deck, in order to better achieve the protective effect of asphalt, it is necessary to test the adhesion of asphalt; the commonly used method for testing the adhesion of asphalt and the adhesive interface is usually the extrusion observation method; To simulate the working environment of asphalt on the road, squeeze the asphalt several times, and then observe the adhesion of the asphalt on the two briquetting blocks to judge the adhesion of the asphalt. [0003] With the existing test device,...

AI Technical Summary

Problems solved by technology

[0003] With the existing test device, the part where the asphalt is squeezed cannot be changed, the size of the extrusion force cannot be adjusted, and there is no relative movement tendency between the briquettes during the extrusion process, which is exactly the same as the actual extrusion force of the asphalt used for road paving. Different, in the actual situation, asphalt usually bears the extrusion force of wheels in different directions and sizes for a long time, resulting in a large error between the test results and the actual situation. Therefore, a new type with high accuracy is urgently needed at present. There are the following problems: 1. The extrusion force of the existing test device cannot be adjusted, and it cannot be adapted to the requirements of test samples of different thicknesses; 2. The extrusion position cannot be changed; 3. The existing In the test device, there is no relative motion trend between the briquetting blocks, which is inconsistent with the actual working conditions of the asphalt on the road; 4. For the sunken rut formed by repeated rolling of a certain area on the existing express bus lane, it is impossible to effectively simulate and observe the asphalt layer changes to obtain the test data required for the corresponding
