Abstract

The invention relates to the technical field of road engineering experiments, in particular to an air pressure type asphalt rapid sampling device which comprises a supporting plate and further comprises a sampling barrel connected with the supporting plate through a connecting barrel; the through holes are uniformly formed in the side wall of the sampling barrel; the sampling mechanism is positioned on the supporting plate; wherein the sampling mechanism comprises a pushing and pressing assembly, a collecting assembly and a suction assembly, the collecting assembly is located in the sampling barrel and installed in cooperation with the through hole, and the collecting assembly comprises a telescopic unit and a material taking unit. And sampling work is carried out at different depths, so that the accuracy of a subsequent detection result is improved, the judgment of workers is prevented from being influenced by deviation, and the practicability of the equipment is improved.

Description

technical field [0001] The invention relates to the technical field of road engineering experiments, in particular to a pneumatic asphalt rapid sampling device. Background technique [0002] Asphalt material is a black-brown complex mixture composed of macromolecular hydrocarbons with different molecular weights and their non-metallic derivatives. The surface is black, insoluble in water but almost soluble in carbon disulfide and carbon tetrachloride. Solid, semi-solid or liquid Organic cementitious material. As a macromolecule amorphous thermoplastic material, when the temperature increases, the asphalt gradually softens from a solid or semi-solid state, resulting in an increase in fluidity, even flowing like a liquid. Fluid solidification is semi-solid or solid, and even becomes hard and brittle when the temperature is below a certain level. [0003] Most of the existing pneumatic asphalt rapid sampling devices can only perform a single sampling work at a fixed height du...
