Abstract

The invention discloses a device for evaluating short-period snow melting performances of a salt-applied snow-self melting road surface. The device provided by the invention comprises an ambient temperature box, an experimental unit, a loading unit and a test unit, wherein the experimental unit, the loading unit and the test unit are arranged in the ambient temperature box. The test unit comprises test pieces, ice and snow bestrewed on the test pieces, a thermal-insulating and water-resisting material arranged each adjacent two of the test pieces, elastic shock pads arranged on the tops of the thermal-insulating and water-resisting materials, porous separator plates arranged at the bottoms of the test pieces, and waterproof material wrapping the test pieces. The loading unit comprises a rolling wheel which can carry out straight reciprocating motion, and a loading device for lifting the rolling wheel, wherein the loading device is installed in a linear-type guide rail and is connected to a radially movable turn plate by a connecting rod and the radially movable turn plate is driven by a motor. The test unit comprises drainage devices, and measuring cylinders which are utilized for holding and measuring solutions and are arranged under the drainage devices, wherein a density measuring instrument and a laser receiving and transmitting device are arranged in each one of the measuring cylinders. The device provided by the invention can be utilized for simulation of a test on short-period snow melting effects of a salt-applied snow-self melting road surface under the action of vehicle rolling, and is mainly utilized for evaluation of short-period snow melting performances of a salt-applied snow-self melting road surface.

Description

technical field

[0001] The invention relates to highway pavement test technology, in particular to a short-term snow-melting performance simulation evaluation test device for self-melting snow-melting road surfaces, which can be applied to the test of short-term snow-melting effects of self-melting snow-melting road surfaces under vehicle load under simulated low temperature conditions, and evaluates short-term snow-melting snow-melting self-melting road surfaces performance. 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...
