Problems solved by technology

At present, the sample making mold of the wet wheel abrasion instrument is composed of two parts: the test mold and the sample gasket. The gaskets for the samples are mostly made of felt paper. Due to the softness of the felt paper itself, it will occur during the test. Misalignment, deformation or even tear damage seriously affect the test results and require manual fixation, which is more dangerous

Abstract

The invention provides an improved device of a wet wheel abrasion tester test mold and a working method thereof. The improved device of the wet wheel abrasion tester test mold comprises a sample containing test mold and a test mold covering piece, the sample containing test mold is of a cylindrical sheet structure, and the outer wall of the sample containing test mold makes contact with the innerwall of a wet wheel abrasion tester test piece tray; wherein a first groove and at least one pair of second grooves are formed in the sample containing test mold, the first groove is used for containing a sample, the test mold covering piece is of an annular structure, the shape of the second grooves is matched with the shape of a wet wheel abrasion instrument test piece clamp chuck, and the second grooves are formed in the circumferential direction of the edge of the sample containing test mold. The two paired second grooves are symmetrical with each other with the circle center of the samplecontaining test mold as the center, the test piece clamp of the wet wheel abrasion instrument can be inserted into the second grooves, the sample containing test mold is fixed into the test piece tray of the wet wheel abrasion instrument, a sample can be firmly locked, the phenomena of deviation, deformation, even damage and the like of the sample are effectively avoided, and the test accuracy and precision are improved.

Description

technical field [0001] The invention belongs to the field of road engineering, and in particular relates to an improved device and a working method for a test mold of a wet wheel abrasion instrument. Background technique [0002] The emulsified asphalt wet wheel abrasion tester can measure the wear resistance, water damage resistance and other related tests of preventive maintenance structural layers such as micro-surfacing and composite sealing layers. At present, the sample making mold of the wet wheel abrasion instrument is composed of two parts: the test mold and the sample gasket. The gaskets for the samples are mostly made of felt paper. Due to the softness of the felt paper itself, it will occur during the test. Misalignment, deformation, and even tearing damage seriously affect the test results and require manual fixation, which is dangerous. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in t...
