Nova Chip ultra-thin wear layer technology is a new technology for road preventive maintenance. It uses special modified asphalt as the binder, which can effectively reduce the thickness of the wear layer. In order to study the material and structural composition of Nova Chip ultra-thin wear layer, this paper analyzes the technical indicators of the raw materials of the ultra-thin wear layer mixture, and obtains the mineral selection type for ultra-thin wear layer mixture. According to the recommended gradation range of the ultra-thin wear layer mixture, the gradation design is carried out. Three kinds of gradation combinations of the ultra-thin wear layer mixture are determined according to the thickness of the wear layer. At the same time, the performance indicators of Nova Chip ultra-thin wear layer are clarified in terms of mechanical properties and functional properties. Finally, the application characteristics of Nova Chip ultra-thin wear layer technology in road maintenance engineering are analyzed, and the applicable scope of Nova Chip ultra-thin wear layer maintenance technology is obtained.
