Problems solved by technology

[0004] At present, the test and reflection of the cohesion performance of asphalt and asphalt binder usually adopts the measurement of force ductility, etc., but the test results are greatly affected by external conditions, and the failure form is complicated, which is quite different from the actual mixture failure form.
The indicators tested and evaluated through experiments cannot accurately reflect the actual performance status, which will affect the road quality and disease control

Abstract

The invention discloses a testing device for the cohesion performance of asphalt binder, which can test the cohesion characteristics of the asphalt binder in tensile and torsional damage under different temperature conditions, including: tensile test parts, anti-torsion Test components, asphalt molds, control area components and structural support components. Tensile test parts are used to test the maximum tensile stress and failure displacement when the sample is damaged by tensile stress; anti-torsion test parts are used to fix the end of the asphalt mold, provide torsional mechanical action and test the damage of the asphalt sample by torque The maximum torque value and relative angular displacement; the asphalt mold is used to pour asphalt or asphalt binder to obtain the mold shape and size of the sample after cooling; the control area components are used to control and display the torque and tensile stress when the sample is finally destroyed , The size of the relative displacement and the change curve of the corresponding index, the structural support component is used to provide mechanical support for each structural component to ensure the overall stability.

Description

technical field [0001] The invention belongs to the technical field of asphalt detection equipment, and in particular relates to an asphalt binder cohesion performance test device, which can be used for selection of raw materials in design and construction, performance research and inspection, and verification and detection of asphalt mixture performance. Background technique [0002] In road engineering, the reasonable selection of raw materials and the quality of their performance are important parts to ensure the quality of the road. If the quality of the raw materials themselves is low, it will directly cause the performance of the asphalt mixture to fail to meet the requirements and cause road diseases. Asphalt pavement is an overall structure with a certain strength formed by asphalt mixture after rolling, and asphalt mixture is obtained by mixing asphalt and aggregate in a certain proportion, among which asphalt or asphalt and mineral powder are mixed. It plays the ro...
