Problems solved by technology
However, the electrothermal method directly provides a large amount of heat to the pavement material. While receiving the heat, the pavement material is also faced with repeated cycles of traffic loads. The superposition of the two factors will cause durability problems for the pavement material.
At present, there is not enough research on the durability of road pavement materials caused by the electrothermal deicing method in academia and engineering circles. Theoretical research depends on the full development of experimental research. At present, the test equipment for studying the durability of pavement materials is not yet mature.

Abstract
The invention provides a road ice melting model test device for simulating traffic load and a test method thereof. The device proposed by the invention is located in a constant temperature model test room and consists of an asphalt road model, a traffic load applying device, a servo oil source and a controller. The asphalt road model includes the surface layer, base layer, subbase layer and cushion layer. It is a standard sample prepared according to the specifications, in which electric heating wires and fiber Bragg grating sensors are embedded in advance. The traffic load application device consists of actuators, traffic load simulation boxes and Composed of a reaction force frame, various traffic load combinations can be controlled and output by controlling the operation of the actuator and the motor. The invention can study the material durability characteristics of the electrothermal ice-melting asphalt road under various working conditions according to the road type, traffic index and climatic conditions. The test phenomenon is easy to observe and the data accuracy is high. The blank of the experimental means.
Description
technical field [0001] The invention relates to a road ice-melting model test device and a test method for simulating traffic load, belonging to the technical field of road engineering. Background technique [0002] Our country has a vast territory, and the winter in the north often faces serious ice and snow problems, especially the accumulation and removal of ice and snow on the road surface has been plaguing the traffic management departments at all levels. billion. All countries in the world have attached great importance to the treatment of road snow and ice for a long time, carried out a large number of related experimental studies, and explored a variety of technical methods to control road snow and ice. At present, the engineering field generally adopts the electrothermal method to solve this problem. The electrothermal method generally provides heat to the interior of the road by laying heating wires to achieve the effect of melting snow and ice. However, the elec...
