Abstract:Material spreader systems are among the largest equipment expenses for winter road maintenance departments. These systems typically include a hopper or similar container to hold a supply of solid granular material; many also include a tank for dispensing a liquid. A chain conveyor or single/double auger system moves the granular material to the spinner, which disperses the material onto the roadway. Agencies often make their spreader purchase decisions after much research, comparison and discussion. This synthesis sought to identify and describe the material spreader systems currently used by Clear Roads member agencies. A national survey of winter maintenance practitioners at state departments of transportation gathered descriptive information about material spreader systems and how they function, assessments of the spreader systems’ operational capacities and effectiveness in a range of weather conditions, and the agencies’ overall satisfaction with the material spreader systems. Supplementing the summary of survey responses in this report are the individual material spreader system descriptions presented in Appendix B. Each system description is presented separately, organized by vendor and in alphabetical order by state, to allow for review and excerpting of individual system assessments.
