Description

Technical Field

[0001] The utility model relates to the technical field of asphalt mixture performance detection, in particular to a green and fast waste asphalt mixture performance detection device. Background Art

[0002] Waste asphalt mixture is mainly used for paving the base or lower layer of roads. Waste asphalt mixture is an important resource. Its reuse is of great significance in saving the use of new materials, reducing the exploitation of natural resources, and saving energy and reducing emissions. Before the waste asphalt mixture is reused, it needs to be tested for performance. The asphalt content inside it is usually tested by the combustion method. This method is based on the principle of the flammability of asphalt and the incombustibility of aggregates. By burning the waste asphalt mixture in a combustion furnace at 480°C, the asphalt content is calculated based on the quality difference of the mixture before and after combustion.

[0003] The common green and fast waste asphalt mixture performance testing device has a relatively simple structure. The placement and removal of test samples in the combustion furnace is usually done manually, which is very inconvenient. The combustion furnace is stable and high, and there is a safety hazard of scalding. In addition, the test samples are stationary in the combustion furnace, which can easily cause uneven heating and combustion, resulting in deviations in the test results. It is not practical enough. Therefore, we propose a green and fast waste asphalt mixture performance testing device. Utility Model Content
