Description

Portable asphalt sampling device based on constant temperature control Technical Field The utility model relates to the technical field of sampling devices, in particular to a portable asphalt sampling device based on constant temperature control. Background Asphalt is a blackish brown complex mixture composed of hydrocarbon compounds with different molecular weights and nonmetallic derivatives thereof, is one of high-viscosity organic liquids, mostly exists in a liquid or semisolid petroleum form, has black surface and is soluble in carbon disulfide and carbon tetrachloride. Asphalt is a waterproof, dampproof and anticorrosive organic cementing material. Asphalt can be mainly divided into coal tar asphalt, petroleum asphalt and natural asphalt, wherein the coal tar asphalt is a coking byproduct. Petroleum asphalt is the residue after crude oil distillation. Natural asphalt is stored underground, and some are formed into mineral deposits or accumulated on the surface of the crust. Asphalt is mainly used in industries such as paint, plastics, rubber and the like, and paved roads and the like. Bitumen typically needs to be sampled before use in order for the laboratory to determine the individual properties of the bitumen material to see if the use requirements are met. At present, a conventional asphalt sampling mode is mainly realized by integrally heating and melting a sample, and the accuracy of the subsequent multiple performance tests of the asphalt sample can be affected. And the heating mode not only consumes a large amount of energy, but also has the heating time as long as about 2 hours, and has long time consumption, thereby prolonging the experimental process. Asphalt can undergo thermo-oxidative aging in the repeated heating process, so that the performance of the asphalt is reduced, and the test result is inaccurate. Disclosure of utility model The utility model aims to provide a portable asphalt sampling device based on constant temperature control, which solves the problems that an asphalt sampling mode provided in the prior art is mainly realized by integrally heating and melting a sample, the accuracy of the subsequent repeated performance test of the asphalt sample is affected, the heating mode consumes a large amount of energy, the time consumption is long, the experimental process is prolonged, the asphalt can undergo thermo-oxidative aging in the repeated heating process, the performance of the asphalt is reduced, and the experimental result is inaccurate.
