Study on Road Performance of Gilsonite Modified Asphalt Concrete Bonding Layer
Gilsonite is selected as a natural asphalt additive,and by adding 6%,7%and 8%gilsonite into the asphalt concrete binder layer,the effect of gilsonite on the performance of asphalt concrete was evaluated by comparing with the mixture without gilsonite.The results show that the stability of the mixture with gilsonite is improved,and the fluidity is increased,resulting in greater deformability of the mixture.When the proportion of gilsonite is 6%,the mixture has the best road performance,indicating that adding an appropriate amount of gilsonite to the asphalt concrete bonding layer can effectively improve the quality and durability of road pavement.
