Abstract

The invention discloses a device for evaluating longer-term snow-melting property of a salinization matter for automatically melting the snows on the road surface and relates to the technique of road surface tests. The device comprises a constant temperature water bath box and a soaking unit and a testing unit which are arranged in the constant temperature water bath box, wherein the soaking unitcomprises a test bracket; a test piece is arranged in the test bracket; the testing unit comprises a temperature measuring device and a density measuring device; and the soaking unit and the testing unit are mutually communicated and are together placed in a closed container. The device provided by the invention can be applied to a test for simulating the longer-term snow-melting effect of the salinization matter for automatically melting the snows on the road surface and can be used for evaluating the longer-term snow-melting property of the salinization matter for automatically melting the snows on the road surface.

Description

technical field [0001] The invention relates to highway pavement test technology, in particular to a long-term snow-melting performance simulation evaluation device for self-snow-melting pavements with salts, which can be applied to the test for simulating the long-term snow-melting effect of self-snow-melting roads for salts, and evaluates the long-term snow-melting performance of self-snow-melting roads for salts. Background technique [0002] Snow and ice on roads in winter has always been a problem that plagues road traffic safety. It usually requires a lot of manpower and material resources to remove ice and snow, so research on actively suppressing frozen roads has also begun. Active anti-freezing technology is to actively adopt related technologies in advance or add special materials to the mixture during engineering construction or overhauling the road surface to make the road surface have special functions to achieve the purpose of snow melting and deicing. One of t...
