International Grooving & Grinding Association

Diamond grinding solves compromised ride quality at the transition between bridge deck segments & approach slabs. To execute successfully & avoid penalties, follow steps like protecting expansion joints & adding additional concrete thickness during paving. ow.ly/GWG350Y8t8w

Nearly 75 yrs ago, the 1st modern use of the grooving process appeared when a single diamond blade was used on a concrete saw to groove pavement. British engineers employed pavement grooving on several airport runways to improve aircraft performance during landing & takeoff. #TBT

IGGA’s John Roberts & Nick Davis had a packed week at this year’s World of Concrete—from engaging with members at our booth to hosting a reception. They also shared insights on industry advancements, pavement preservation & more in several interviews. ow.ly/WyaV50Yh1qf

30 years ago,  @PaveConcrete recognized @GADeptofTrans for its "outstanding commitment & achievements in concrete pavement restoration," noting that Georgia was the first to combine various techniques into a comprehensive system of repairs known as CPR.  #ThrowbackThursday

#DidYouKnow? Combining diamond grinding & concrete pavement rehab (CPR) can significantly extend a pavement's service life. This strategy was chosen for US Hwy 12 in MN to address aging concrete pavement, drainage issues & more. Read the case study here: ow.ly/ekgg50YceOp

60+ yrs ago, a section of the San Bernardino Freeway became the site of the 1st major #diamondgrinding project on a US highway. This project corrected excessive faulting, and the success of this 1M-sq.-ft. effort spawned the modern #concretepavement restoration industry. #TBT

Via @PavementMag , IGGA’s Nick Davis shares tools to manage rising highway #construction costs. By applying preservation treatments at the right time, future major repairs can be significantly reduced & long-term performance of concrete assets ensured. ow.ly/pWgt50Y8eM2

The Lauderdale-Hollywood Airport runways were experiencing pavement friction loss . Based on a design engineer's recommendations, 110K sq yds of asphalt runway were diamond ground and regrooved. At the time, diamond grinding a major runway was a first for Broward County, #TBT

Our team was energized throughout #WOC2026—connecting with members & visitors at our booth, visiting member exhibits & sharing the many benefits of being part of the IGGA. Great opportunity to connect and celebrate our industry. ow.ly/SJ1b50Y4QWt #GetYourGrooveOn

Gavin Jenkins from @roadeditor talks with IGGA’s Nick Davis at #WOC2026 on U.S. #concrete pavements, #sustainability, costs and new materials. Watch it here: ow.ly/IvLI50Y4vbM

Nearly a decade ago, the City of Chicago turned to a durable treatment solution for the Dan Ryan Expressway. The work included grooving portions of existing concrete road surfaces to enhance traction & wet-weather safety on tight curves. ow.ly/F6Jh50XWPuj #TBT

It’s here! #WOC2026 is underway and we’re proud to cosponsor and pumped to see the latest advancements in concrete products and technology and connect with so many industry pros from around the globe. Be sure to stop by our booth in the Central Hall—C4332. #TakeItToTheMax

It’s been almost a year since Roads & Bridges caught up with IGGA's Nick Davis at the #WOC2025 to discuss improving investments and safety in the industry. Check it out: ow.ly/K76A50UOEhe #ThrowbackThursday

Route 66 is turning 100! Spanning from Chicago to Santa Monica, it continues to serve travelers thanks to preservation techniques like #diamondgrinding & joint sealing--a living testament to the enduring strength & reliability of #concrete pavement. tinyurl.com/4xhntaw8

As we begin 2026, we reflect on a successful 2025 & look forward to what's ahead. Last year was marked by significant progress in promoting the value and proper use of pavement preservation & restoration. Join us in building on this momentum! igga.net/membership

As we approach the new year, we extend our sincere gratitude to our members, partners and the entire concrete pavement community for your support, dedication and hard work. We look forward to the innovations & opportunities in the coming year. Wishing you a very #HappyNewYear.

As the year comes to a close, we extend our warmest wishes to all our members, partners and industry colleagues for a safe and joyful holiday season. We look forward to another year of collaboration and innovation. #HappyHolidays from all of us at the IGGA.

In 2023 we shared an update on Trunk Highway 210, west of Brainerd, MN. First constructed 71 yrs ago, most of the original 7 miles of concrete were still in service in 2023 (and remain today)—an incredible investment on behalf of Minnesota taxpayers. ow.ly/B8au50XKhWL #TBT

Don’t suffer paralysis by analysis! While technologies have evolved, roadway safety principles remain constant. A landmark 1972 report offers data that continues to inform safety practices today. Its findings are as relevant now as they were decades ago. conta.cc/49dhPGf

In 1995, we joined @PaveConcrete to create the Concrete Pavement Preservation Partnership. CP3 now serves as the technical resource & industry rep in marketing optimized pavement surfaces, concrete pavement restoration & pavement preservation. ow.ly/VxCV50XHoZ1 #TBT
