Abstract

The invention discloses a test device and method for testing interface adhesion of asphalt aggregates. The test device comprises a controller, a base, a timer, a glass housing, a first electric telescopic rod, a second electric telescopic rod, a cross rod, a heating device, a driving device and a first test component, wherein the first electric telescopic rod, the second electric telescopic rod, the cross rod, the heating device, the driving device and the first test component in the glass housing; the first test component comprises a first sample receiver and a first stirrer. The device and the method can be used for accurately testing the interface adhesion of the asphalt aggregates.

Description

technical field [0001] The invention belongs to the technical field of test devices for asphalt and asphalt mixtures in highway engineering, and relates to a test device and method for testing the interface adhesion of asphalt aggregates. Background technique [0002] With the continuous development of my country's transportation industry, the highway mileage has achieved unprecedented growth, but the early damage of the road surface, especially the early water damage of the asphalt pavement, has become an important influence that reduces the service performance of the road surface and the stability of the pavement structure. One of the factors has attracted the general attention of the highway industry. At present, the tests used to study the adhesion of asphalt and aggregates are usually the water boiling method and the water immersion method. The test principles, objects, and operation methods of the two are different. Advantages and disadvantages. However, in the prior art...

[0002] With the continuous development of my country's transportation industry, the highway mileage has achieved unprecedented growth, but the early damage of the road surface, especially the early water damage of the asphalt pavement, has become an important influence that reduces the service performance of the road surface and the stability of the pavement structure. One of the factors has attracted the general attention of the highway industry. At present, the tests used to study the adhesion of asphalt and aggregates are usually the water boiling method and the water immersion method. The test principles, objects, and operation methods of the two are different. Advantages and disadvantages. However, in the prior art, when dealing with asphalt aggregates, the test time has to be fixed, and the stirring and filtering are all done manually. Human factors and the external environment are greatly affected, so the adhesion test is seriously affected. the accuracy of
