In selecting a material spreader, agencies have many choices: tailgate vs. slide-in, conveyor systems vs. augers, spinners vs. chutes, and more. Many spreaders have prewetting capabilities. Zero-velocity systems can help minimize bounce and scatter, as can add-ons like skirts and flaps. Clear Roads research aims to help agencies determine the most effective, cost-efficient system for their needs.
