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.

Implementation of NGCS in the North Split Project
The deployment of next generation concrete surface (NGCS) technology in the North Split project involved several key stages. Planning and design along with material and construction. The benefits of NGCS technology is noise reduction, improved safety and enhanced smoothness. The North Split project in Indiana serves as a benchmark for the successful implementation of NGCS technology in large-scale infrastructure projects.
