Description

Technical Field

[0001] The utility model belongs to the field of asphalt detection, and particularly relates to an asphalt content detection device for an asphalt pavement. Background Art

[0002] Asphalt is a dark brown complex mixture composed of hydrocarbons of different molecular weights and their non-metallic derivatives. It is a kind of high-viscosity organic liquid. It mostly exists in liquid or semi-solid petroleum form. It has a black surface and is soluble in carbon disulfide and carbon tetrachloride. Asphalt is an organic gelling material that is waterproof, moisture-proof and corrosion-resistant. In construction, a measuring instrument is needed to measure the asphalt content. When the detection device is in use, the asphalt content needs to be tested after combustion.

[0003] When testing asphalt in the prior art, the asphalt is usually placed directly on a testing table for testing. When the testing head is inserted into the asphalt, the asphalt is easily moved, which reduces the asphalt testing effect and the usability of the device. At the same time, the existing testing device performs the test after the asphalt on the surface of the testing table is burned. A large amount of smoke gas is easily generated inside the testing device, and the smoke gas contains a large amount of harmful gases such as carbon monoxide. Direct emission is likely to cause pollution to the surrounding environment, thereby reducing the practicality of the device. Utility Model Content
