In order to provide reference for design and construction of lownoise asphalt road, the effect of flatelongated particle content on driving vibration noise was studied. The relationship between driving vibration noise and tireroad contact pressure was investigated by theoretical analysis, field noise tests, and simulations via the discrete element method (DEM). Besides, a new evaluating method for driving vibration noise based on tireroad contact pressure was proposed. The asphalt pavement models with four flatelongated particle contents were built using particle flow code (PFC). Meanwhile, the movement of wheels on these four different pavement surfaces was simulated and the contact pressures were calculated. Finally, the volatility of contact pressure was analyzed. The results show that the effect of flatelongated particle content on driving vibration noise is insignificant at the level of 0, 10%, and 15%. However, the driving vibration noise of asphalt pavement with 20% flatelongated particles is greater than those with lower flatelongated particle content. Thus it can be concluded that excessive flatelongated particle content has a negative influence not only on workability and strength of asphalt mixture, but also on driving vibration noise.
