Abstract

The invention discloses a test device for a shearing property of a multipurpose interface and a test method thereof. The test device comprises an environmental cabinet and a test piece arranged in theenvironmental cabinet; the test device is characterized in that fixing devices are arranged on the periphery of the test piece; a horizontal loading device and a horizontal displacement sensor are arranged on a horizontal plane of the test piece; a vertical loading device is arranged on a vertical plane of the test piece; a horizontal force presser and a horizontal stress sensor are arranged between the horizontal loading device and the test piece; a vertical force presser and a vertical stress sensor are arranged between the vertical loading device and the test piece; a controller is arranged on the exterior of the environmental cabinet; the controller is electrically connected with the horizontal stress sensor, the vertical stress sensor and the horizontal displacement sensor. The testdevice is capable of realizing real-time recording and monitoring of extreme damage and fatigue destructive property data of the shearing interface so as to finish test. The test device disclosed by the invention can be used for testing the mechanical properties of the shearing interface. The test data can be used for effectively evaluating shear strength and shearing fatigue property of various compound structures, such as paving interlayer interfaces and different dielectric material shearing interfaces.

Description

technical field [0001] The invention belongs to the field of concrete material and structural performance research, in particular to a multipurpose interface shear performance test device and a test method thereof. Background technique [0002] The pavement structure is composed of different hierarchical structures according to the layered system. The interface shear performance is the key index to ensure the mechanical properties of the multilayer composite structure. Good interlayer shear strength and shear durability play a role in improving the service life of the structure. play a vital role. In the field of civil engineering, especially in terms of road pavement structures, different structures are bonded together by sprinkling adhesive materials, such as sprinkling emulsified asphalt to bond the asphalt pavement surface and the lower layer as a whole, or sprinkling epoxy asphalt Bond the steel bridge deck with the asphalt pavement as a whole. However, due to the inf...
