Optimization of Patching for Spray Injection Equipment

This study evaluated the performance and durability of various asphalt emulsion and aggregate material combinations to identify the most suitable materials for use with the spray injection method in Ohio. This study included a user survey to document the current spray injection practices in Ohio, laboratory testing of materials to be used with the spray injection method, and field evaluation of various asphalt emulsion-aggregate material combinations that were installed at eight test sites in three Ohio Department of Transportation (ODOT) districts. Based on the findings of this study, the research team developed asphalt emulsion and aggregate material specifications for use with the spray injection method, provided ODOT with recommendations on storage and handling of asphalt emulsions, and developed an optimized distribution strategy for spray injection materials, including suggestions on the purchase of an asphalt emulsion storage tank.
