Abstract

The invention discloses an asphalt aging instrument which includes a material bench, and an electrode being connected to the material bench to drive the material bench. The rotation speed of the material bench is 15 + / - 0.2 r / min. The material bench is driven by a motor so that the material bench can be rotated at a constant rate, so that materials are irradiated and sprayed uniformly, thereby achieving a result having better scientificity.

Description

technical field [0001] The invention relates to the technical field of machinery, in particular to an asphalt aging instrument. Background technique [0002] Asphalt is an important material in road construction. The aging / hardening of asphalt has a great influence on the performance of asphalt, which is related to the service life of the road surface. The aging of asphalt leads to the decline of asphalt plasticity, poor ductility, and finally loss of use value. The main reasons for asphalt aging are: the active deterioration of the material itself, the influence of sunlight, air oxidation, temperature changes, and the influence of water and humidity. At present, the research methods of asphalt aging mainly include natural aging method and simulated aging test. [0003] At present, the methods for simulating aging tests include: oxygen absorption method, reversed-phase gas-liquid chromatography, film oven method and rotating film oven method (RTFOT). [0004] Rotating film...
