▎ 摘　　要

NOVELTY - Asphalt mixture comprises 80-85 pts. wt. aggregate, 10-12 pts. wt. base asphalt, 3-4 pts. wt. mineral powder, 2.5-3 pts. wt. modified graphene oxide, 2-3 pts. wt. modified fiber, and 2-3 pts. wt. filler. The modified graphene oxide is prepared by adding graphene oxide into deionized water, ultrasonically dispersing for 15 minutes, adding polyethyleneimine, heating to 80°C, and stirring for 8 hours, centrifuging and freeze-drying to obtain pretreated graphene oxide, adding the pretreated graphene oxide and sodium lignosulfonate into water, stirring and dispersing, adding potassium persulfate and N,N'-methylenebisacrylamide, reacting, filtering, washing with water and drying. USE - The asphalt mixture is useful for ultra-thin overlay pavement. ADVANTAGE - The asphalt mixture has good solid cross-linking network, enhanced stability, improved low temperature crack resistance, and improved durability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the preparation method of asphalt mixture for paving ultra-thin cover.
