What is the application rate for open graded friction course (OGFC) FC-5?

The application rate for Open Graded Friction Course (OGFC) FC-5 is indeed 0.045 gallons per square yard. This specific application rate is important because it provides the optimal amount of material required to achieve the desired performance characteristics of the OGFC surface. OGFC is designed to enhance safety by improving skid resistance and reducing hydroplaning risks on wet surfaces. The precise measurement of 0.045 gal/yd² ensures that the surface retains the necessary properties for effective drainage while also meeting structural and durability requirements. This careful calibration reduces the potential for issues stemming from excess material, which may lead to decreased performance or increased maintenance costs.
