Control deck grades to accommodate equipment and avoid joint damage Increasingly, owners are specifying diamond grinding to improve the ride quality, friction and drainage capabilities of new bridge deck surfaces. Historically, bridges have suffered from ride quality issues where adjoining bridge deck segments and approach slabs meet one another. To counter this issue, agencies are now specifying that the final riding surface be diamond ground.   Diamond grinding provides a m

Baytown, TX Project Delivers Superior Ride Quality In 2021, the City of Baytown, Texas, completed a landmark road preservation project on North Main Street, one of its busiest corridors. By adopting a Concrete Pavement Preservation (CPP) strategy, the city not only saved millions in reconstruction costs but also delivered a roadway with exceptional ride quality, setting a new standard for infrastructure renewal. This project serves as a compelling case study for how t

The City of Minneapolis is setting a new standard for sustainable urban infrastructure renewal through its comprehensive Concrete Pavement Preservation (CPP) strategy. Facing the challenges of harsh freeze-thaw cycles and heavy urban traffic, the city's approach provides a valuable model for extending the life of concrete streets.  Since its launch in 2016, the program has demonstrated significant success in rehabilitating its aging concrete street network. By expanding on i

A durable, sustainable alternative to traditional asphalt overlays A recent peer-reviewed paper by George Vorobieff, a leading subject matter expert on concrete pavements, presents a compelling case for using conventional diamond grinding (CDG) of concrete bridge decks as a primary alternative to waterproofing, challenging the long-standing practice of applying a membrane and asphalt overlay. The paper, " To waterproof bridge decks or not ," details how CDG offers a high-perf

Across the country, departments of transportation are employing diamond grinding to enhance pavement performance and often take a targeted approach to smooth out uneven spots in a pavement in an effort to minimize costs. This practice, called bump grinding, is designed to address only troublesome locations and thereby conserve resources while meeting smoothness requirements. While bump grinding may appear to conserve resources, in some situations this selective approach can r
