Active deicing technologies, such as conductive asphalt concrete and heating cable, are not applicable to the existing roads, and passive deicing based on mechanical methods damage the roads. A novel scraping deicing system for thin ice using end-of-life wire ropes was proposed, and the scraping deicing mechanism was given to optimizing the inclination angle for minimal external deicing force. The prototype was developed and fabricated, and a laboratory deicing experiment was designed to evaluate the deicing performance for a prefabricate frozen asphalt concrete block (ACB). The results showed that the deicing brush could naturally clean with the thickness of the ice layer of 10 mm. There was good stability when the deicing brush's rotation speed reached 500 r/min, and the removal rate can get 92 %. No apparent scratches occurred on the upper body of the ACB, which will not cause severe damage to the pavement surface.
