This is the final report of PlusRide being used as the wearing course on a bridge deck overlay.
A Class D Asphalt Concrete Pavement which is an open graded friction course was used on an adjacent bridge as a control for the PlusRide. The PlusRide claims were high friction resistance, reduced noise, increased fatigue properties and deicing characteristics. The PlusRide cost 50 percent more than the Class D and the friction resistance, noise levels and fatigue properties were the same for the PlusRide and Class D. The deicing characteristics could not be confirmed due to the absence of surface icing on highways in the Yakima area.
