Induction heating and microwave heating asphalt pavement multifunctional hot milling construction method

Abstract

The invention discloses an induction heating and microwave heating asphalt pavement multifunctional hot milling construction method. The method comprises the steps that a pavement material is judged;a heating mode is determined; according to the area size and position of the part needing to be milled, a mechanical arm controls a heating mechanism to move, permutate and combine to correspond to aheating position; a power supply is started, heating is started, a water pump is started to cool the heating device, and a heating vehicle slowly moves at a certain speed; and the heated part is milled. The problems that the milling effect is poor due to the poor heating effect on different pavements, and a traditional milling mode of steel bridge deck asphalt is not suitable can be solved.

Description

technical field [0001] The invention relates to the technical field of thermal milling of asphalt pavement, in particular to a multifunctional thermal milling construction method of asphalt pavement by induction heating and microwave heating. Background technique [0002] With the rapid development of the country's national economy, transportation, as the key to rejuvenating the country and the foundation of a strong country, has also achieved world-renowned development achievements. Roads are the basis of traffic, and only by ensuring the quality of roads can the development of traffic be ensured. However, the asphalt pavement directly bears the traffic load, and is prone to severe fatigue cracks and rutting, which adversely affect traffic safety and driving comfort. Therefore, it is imperative to repair the asphalt pavement. [0003] The repair of asphalt pavement needs to remove the diseased parts first. Now the commonly used removal method is hot milling, using heating...
