Largest Asphalt Safety Grooving Project in U.S. History
Longitudinal safety grooving can deliver a safer, more durable roadway for travelers while also achieving
substantial cost savings. The Missouri Department of Transportation (MODOT) recently completed a significant pavement preservation project on Interstate 70 in Montgomery County. By leveraging value engineering, the department successfully enhanced roadway safety while achieving substantial cost savings. This project highlights the effectiveness of longitudinal safety grooving as a viable, resource-efficient alternative to traditional asphalt overlays.

Revolutionizing Rut Repair with Calcium Sulfoaluminate Cement (CSA)
The challenge of repairing wheel ruts on concrete pavements is a persistent issue for infrastructure maintenance, particularly in regions with heavy snowfall and tire chain usage. A promising rut repair method calcium sulfoaluminate (CSA) cement, was chosen as a cost effective, easy-to-use and longer-lasting repair material for a project executed by ACME Concrete Paving Inc. in collaboration with the Washington State Department of Transportation (WSDOT), to remediate pavement ruts.
