Abstract

Provided are a device and method for testing an ice suppression effect of a salinization matter asphalt mixture. The device comprises a mainframe control device, a testing device and a test piece placing device for placing a test piece having formed ice through an icing device. The test piece placing device is arranged on the testing device, and the mainframe control device is connected with the testing device. The test piece icing device comprises a baffle and a test piece groove which are connected, the baffle is arranged on the test piece groove. The test piece icing device enables semicircular ice layers with required thicknesses to be frozen between two sides of intermediate standard Marshal test pieces in 3 standard Marshal test pieces and standard Marshal test pieces on the two sides. The device is simple in structure, and the ice suppression effect can be tested accurately. The device is simple in testing principle, easy to manufacture, simple and convenient in determination operation, economical and practical, and the problems that an existing ice suppression effect testing method is low in efficiency, poor in precision and large in human factor influence are solved.

Description

technical field [0001] The invention belongs to the technical field of snow melting and ice suppression of salt asphalt mixture, and relates to a test device and a test method for the ice suppression effect of salt asphalt mixture. Background technique [0002] At present, the snow melting and ice suppression technology of salt asphalt mixture is a new type of active snow melting and deicing technology. Slow-release ice suppression materials are added to the mixture inside the pavement. Enters the pavement surface through capillary channels. Under the action of capillary pressure and vehicle load dynamic pressure, the salt particles are separated from the asphalt oil film and mixed with water to form a solution, and a water film is formed between the road surface and the ice layer. With the continuous precipitation of the salt material, the concentration of the salt solution continues to rise, and at the same time, the solute in the solution flows to the place with a lower ...
