A multifunctional ice and snow melting road surface test device and evaluation method

Abstract

The invention discloses a multifunctional ice or snow melting pavement test device and an evaluation method.The multifunctional ice or snow melting pavement test device is characterized in that a sealed case used for establishing a test environment is arranged; a test platform is arranged inside the case, a test piece to be tested is put on the test platform, and an ice or snow tank is arranged on the top of the test piece to be tested; an ice or snow pipeline is additionally arranged and used for putting ice or snow into the ice or snow tank; the test piece which is to be tested and used for simulating an ice or snow melting pavement is provided with a lower pavement layer, a middle heating layer and an upper pavement layer in a layered mode; a concrete precast element is adopted as the middle heating layer and provided with hole channels in an array mode, and strain pieces stick to the hole walls of all the hole channels; heating elements are put into the hole channels at set positions, heating holes are formed, and concrete rods are put into the hole channels without the heating elements to fill the hole channels.According to the multifunctional ice or snow melting pavement test device and the evaluation method, simulation tests of the deicing or snow melting process can be conducted according to different working conditions and pavement structures and different deicing or snow melting modes, the ice or snow melting efficiency and speed and the fatigue life are obtained, an optimal scheme is obtained by means of evaluation to the ice or snow melting pavement, and therefore the ice or snow melting pavement can be better applied.

Description

technical field [0001] The present invention relates to a multifunctional ice and snow melting pavement test device and evaluation method, more specifically, a kind of ice and snow melting method for simulating different working conditions, different road surface structures, and different ice and snow melting methods such as electrothermal method or thermal fluid method. process, and further obtain the ice and snow melting efficiency, rate and pavement fatigue life, and then evaluate the ice and snow melting pavement scheme. Background technique [0002] Snow and ice on roads seriously threaten traffic safety. The commonly used method of deicing snow and manpower using manpower and mechanical equipment consumes a lot of manpower and material resources; the use of ice and snow melting pavement can quickly remove ice and snow on the road surface, and the more typical one is electric heating or fluid heating ice and snow melting pavement, which is pre-buried in cement concrete ...

AI Technical Summary

Problems solved by technology

Some test devices in the prior art have a single function, and cannot conduct simple and effective comparison tests for different environmental conditions, pavement structures, heating power or fluid temperature, which greatly limits the specific application of snow-melting roads
