Research on the Application of Ultra-thin Wear Layer in Preventive Maintenance Engineering of Asphalt Pavement on Expressway
Based on the example of the G75 Wugu Expressway pavement improvement project,this article conducts a detailed study and discussion on the design,construction method,and application effect of the ultra-thin wear layer material prepared by modified Novabinder asphalt mixture.It is concluded that the ultra-thin wear layer pre-pared from modified Novabinder asphalt mixture meets the standard specifications in terms of thickness,width,structural depth,friction coefficient,water permeability coefficient,and smoothness,which can improve the road performance of the original highway asphalt pavement and optimize its driving performance.
