Air pressure type solid asphalt sampling device

Abstract

The invention discloses an air pressure type solid asphalt sampling device, comprising a asphalt sampler, a motor enabling the bitumen sampler to rotate, and handrails enabling the bitumen sampler to press downwards, wherein the bitumen sampler comprises a bitumen sampling bucket of which the bottom is open, the bitumen sampling bucket is provided with a heating device, the top of the bitumen sampling bucket is communicated with an air pressure control chamber, and the air pressure control chamber is connected with the motor by a mechanical arm. The problems that a sample is aged in a asphalt sampling process, the environment is polluted, and the like are avoided, and the problems of low efficiency and insufficient safety of a laboratory asphalt taking technology are solved; the device is simple in structure and reasonable in design, and can be used to quickly take the asphalt sample from an asphalt storage bucket.

Description

technical field [0001] The invention belongs to the technical field of road engineering experiments, and relates to the technical field of designing and manufacturing road engineering laboratory instruments, in particular to a pneumatic solid asphalt sampling device. Background technique [0002] Since the 1990s, with the sustained and rapid development of China's economy, the construction of expressways has also advanced rapidly. By the end of 2014, the total mileage of expressways in my country had reached 111,900 kilometers, surpassing the United States and ranking first in the world. The use performance and driving comfort account for more than 90% of the highways and first-class highways that have been built in my country. [0003] Asphalt material is a dark brown complex mixture composed of high molecular weight hydrocarbons with different molecular weights and their non-metallic derivatives. The surface is black. It is insoluble in water but almost soluble in carbon di...
