Every year, more countries are adding diamond grinding and grooving to their road maintenance toolboxes. Diamond grinding is a cost-efficient and sustainable way to revitalize concrete roads, improving the functional and structural longevity of the pavements.

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.

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.

To enhance the smoothness and overall driving experience on bridge decks, the Illinois Department of Transportation (IDOT) implemented a new policy on diamond grinding overlays. The U.S. 30 bridge project significant improved smoothness and resulted in a quieter deck due to the transition from transverse to longitudinal grooving and overall reduction of surface roughness.

Construction for The Finish Line, also known as Section 6, includes 27 miles of new interstate highway, as well as work on the heavily traveled I-465 between I-70 and I-65 on Indianapolis’s southwest side. It entails either replacement, rehabilitation or new construction for 42 bridges. Concrete paving will be used on all of them, and many will be surfaced using Next Generation Concrete Surface (NGCS).

In 2019, the Minnesota DOT (MNDOT) announced a project to reconstruct and expand both directions of I-94 between TH25 in Monticello and TH24 in Clearwater, approximately 35 miles northwest of Minneapolis. The standard mitigation technique requires the construction of expensive noise walls. However, the geography of the site and the proximity of the lake to the roadway made the construction of noise walls exceedingly difficult. In response to this challenge, HcPCi provided data showing that using next generation concrete surface (NGCS) would provide noise reduction meeting MnDOT’s mitigation requirements.
