Gilsonite is selected as a natural asphalt additive, and by adding 6%, 7% and 8% gilsoniteinto the asphalt concrete binder layer, the effect of gilsonite on the performance of asphalt concrete wasevaluated by comparing with the mixture without gilsonite. The results show that the stability of themixture with gilsonite is improved, and the fluidity is increased, resulting in greater deformability of themixture. When the proportion of gilsonite is 6%, the mixture has the best road performance, indicatingthat adding an appropriate amount of gilsonite to the asphalt concrete bonding layer can effectivelyimprove the quality and durability of road pavement.
