Abstract

The invention discloses a conduction type bituminous mixture, a preparation method and a self-snow-melting system of the conduction type bituminous mixture. The conduction type bituminous mixture comprises coal gasification fine slag, stone and bitumen. The self-snow-melting system comprises a bituminous pavement formed by paving the conduction type bituminous mixture, a first plate electrode, a second plate electrode, an on-off actuator, a temperature sensor, a controller and a photoelectric converter; the first plate electrode, the second plate electrode, the on-off actuator, and the temperature sensor are arranged under the bituminous pavement; the controller and the photoelectric converter are arranged outside the bituminous pavement; the temperature sensor is used for obtaining the real-time temperature of the bituminous pavement and sending the real-time temperature to the control input end of the controller; the controller is used for controlling the on and off of the on-off actuator according to the real-time temperature. The self-snow-melting system adopts the coal gasification fine slag as a bituminous mixture filler of pavement layers of highway bridge decks in cold highland areas, a photovoltaic power generation system is used as a power supply, based on the information technologies such as mobile Internet and sensors, under special climatic environments, a self-snow-melting ice-inhibition function of the bridge deck pavement layer is realized, and the function of traffic safety early warning is reached.

Description

technical field [0001] The invention relates to the field of highway engineering asphalt pavement, in particular to a conductive asphalt mixture, a preparation method and a self-melting snow system. Background technique [0002] With the rapid development of my country's highway industry, expressways have gradually extended to plateau mountainous areas and even western alpine and high-altitude areas, and the proportion of roads, bridges and tunnels has increased significantly. Due to the large temperature difference in high-altitude and high-altitude areas, snowfall and freezing weather often occur, and snow and ice often appear on the pavement layer of the bridge deck, resulting in a sharp decrease in the friction coefficient and adhesion between the car tire and the pavement layer, and the braking distance is extended. Automobiles are prone to skidding or even rollover, causing brake failure, loss of direction control, and serious traffic accidents. In addition, the wirel...
