Abstract

The invention relates to a light-water coupling asphalt aging instrument, which belongs to the technical field of aging test to the asphalt. According to key characteristics of the invention, a quartz glass layer is fixed below a high pressure mercury lamp in a main machine which is provided with the high pressure mercury lamp and a temperature control motor, and a rainfall simulation device is arranged below the quartz glass layer. The addition amount of water in a specimen disc can be precisely controlled by automatically controlling the total amount of the water in a storage water box according to the experiment need; the addition amount of the water in the specimen disc also can be controlled by controlling the opening time of an electromagnetic valve. A waterproof quartz glass material can be automatically replaced by the material with the light intensity absorption capacity satisfying the experiment condition according to the experiment need. The light-water coupling asphalt aging instrument is simple in process and safe to operate. The light-water coupling asphalt aging instrument has the beneficial effects that (1) a rainfall environment is coupled with an ultraviolet aging test condition, so that the experiment condition is increased; (2) the intensity of the ultraviolet light can be controlled by replacing a waterproof layer with different light intensity absorption capacities, so that the experiment condition of the equipment can be enriched; (3) different rainfall capacities can be realized by controlling the water mount in the storage water box.

Description

technical field [0001] The invention relates to a light-water coupling asphalt aging instrument, which belongs to the technical field of asphalt aging testing, and specifically refers to the improvement of an existing experimental equipment capable of performing asphalt ultraviolet aging, so that it can perform asphalt aging while performing asphalt ultraviolet aging. Water aging, this experimental device simulates the aging of asphalt under the combined action of ultraviolet light and water, in order to explore the ultraviolet aging of asphalt under the rainfall environment. Background technique [0002] In recent years, with the increasing proportion of asphalt pavement in our country, the phenomenon of structural damage of asphalt pavement caused by aging has gradually attracted people's attention. The aging of polymer materials caused by asphalt absorbing ultraviolet light and oxygen is called the ultraviolet aging phenomenon of asphalt. At present, the research on the ...
