GET A GRIP : THE NEWLY REPAVED INDIANAPOLIS MOTOR SPEEDWAY GIVES TIRES SOMETHING TO HOLD ONTO

This article profiles the repaving of the Indianapolis Motor Speedway. The main problems that were faced consisted of attaining new levels of evenness without sacrificing grip. Drivers wanted the increased traction they had been accustomed to, and as a result, the speedway management decided to diamond grind the entire track surface in order to give a consistent amount of grip. With a diamond grinding process, shallow grooves are cut in the pavement surface, providing a grip to race cars that have no tread. The article describes how a stone matrix asphalt (SMA) mix with significant coarse aggregate and high stone-on-stone contact was chosen for its strength and durability. Rut-resistance and an impermeable surface were achieved through two lifts of SMA.
