Problems solved by technology

[0003] At this stage, the indoor test for the bonding performance test of the interlayer binder is generally to apply the interlayer binder after the separate preparation of different concrete structural layers to bond the materials of each structural layer, which is different from the interlayer binder and the concrete structure. It is difficult to accurately control the thickness of the bonding material, and in order to meet the size of the test equipment, it is usually necessary to cut the test piece, which affects the interlayer bonding performance to a certain extent. Therefore, in order to facilitate the integrated formation of the interlayer binder and the concrete structure layer and meet the actual engineering requirements, the thickness of the binder between the concrete structure layers should be precisely controlled. Due to the bonding ability of different types and thicknesses of interlayer binders, it is urgent to develop a forming mold and its test method that can adjust the thickness of the interlayer bonding of concrete

Abstract

The invention relates to a molding mould capable of adjusting the concrete interlayer bonding thickness and a test method thereof, and belongs to the technical field of road engineering in traffic engineering. The mould comprises structures such as a base, a thickness adjusting steel plate, a rectangular mould frame, an adjusting screw, a fixing nut, a propelling plate, an adjusting screw rod, a leveling bolt, a fixing block and a counterforce frame. Different concrete mixing materials are added manually, the thickness between the different concrete materials and the interlayer bonding material can be precisely controlled, the conformity of the size of the materials of each structural layer is maintained, integral forming of the interlayer bonding material and the concrete structural layercan be simply, conveniently and rapidly achieved, meanwhile a test piece can be convenient to dismount and mount, the disturbance of human factors to the interlayer bonding capability can be avoidedto the maximum extend, and accordingly the bonding ability between road surface material layers can be accurately reflected.

Description

technical field [0001] The invention belongs to the technical field of highway engineering in traffic and transportation engineering, and in particular relates to a forming mold with adjustable interlayer bonding thickness of concrete and a test method thereof. Background technique [0002] In road engineering, the pavement structure is paved in layers, and the layers are usually treated with adhesive materials. However, the theoretical research and practical research on the existing interlayer bonding ability are not perfect, resulting in a large number of pavements due to the selection of interlayer bonding materials. And premature failure due to improper design. Therefore, it is essential to increase the interlayer bonding ability, improve the interlayer bonding effect, and correctly evaluate the interlayer bonding effect. [0003] At this stage, the indoor test for the bonding performance test of the interlayer binder is generally to apply the interlayer binder after th...
