Abstract

The invention provides a low-temperature asphalt mixture material performance pressure testing method, and relates to the field of asphalt. The material performance pressure testing method for the low-temperature asphalt mixture comprises the following steps of: S1, preparing experimental articles to be used, and additionally arranging a comparison thermometer and a monitoring camera on the original basis; S2, respectively connecting the comparison thermometer with a sample cylinder and an instrument; S3, carrying out adjustment preparation on the instrument before an experiment; S4, preparing an asphalt sample; and S5, selecting a corresponding rotor according to the pre-estimated asphalt viscosity. According to the material performance pressure testing method, the monitoring camera is arranged, the monitoring camera is aligned with a display panel of the instrument, the monitoring camera is preselected to shoot every 60s, shooting is carried out for three times, results obtained by the monitoring camera are compared with computer data, absolute accuracy of final viscosity data is guaranteed, through the setting, multiple groups of reference objects are added, the accuracy degree of experimental data can be greatly improved, and the possibility of accurate working parameter errors and experimental data dislocation in the experimental process is prevented.

Description

technical field [0001] The invention relates to the technical field of asphalt mixture, in particular to a pressure test method for low-temperature asphalt mixture material performance. Background technique [0002] Asphalt mixture is a composite material, mainly composed of asphalt, coarse aggregate, fine aggregate, mineral powder, and some polymers and wood cellulose are added; different structures are formed by mixing these materials with different qualities and quantities. And have different mechanical properties. Asphalt mixture is a general term for the mixture made by mixing mineral aggregates and asphalt binder. According to the material composition and structure, it can be divided into continuous gradation and discontinuous gradation mixture. According to the mineral material gradation composition and porosity, it can be divided into dense gradation, semi-open gradation and open gradation mixture. According to the size of the nominal maximum particle size, it can...
