Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of asphalt detection sampling, and particularly relates to an asphalt detection sampling device. BACKGROUND

[0002] Asphalt sampling is a process of obtaining a representative asphalt sample, which is crucial for accurately evaluating the quality and performance of the asphalt. The accuracy of sampling will directly affect the subsequent detection results of the asphalt, such as the determination of penetration, softening point, ductility and other indicators. The core drilling machine drills into the asphalt layer through a rotating drill bit. The drill bit is generally hollow, and during the rotary drilling process, the asphalt is cut by the drill bit and enters the hollow part inside the drill bit, forming a cylindrical asphalt core sample. After the coring work is completed, the sample is difficult to remove from the hollow drill bit, and the hollow drill bit needs to be hit to discharge the internal sample, which causes great damage to the hollow drill bit and poor sample integrity.
