How Florida is advancing roadway safety with new pavement grooving trials Florida is taking a proactive approach to roadway infrastructure by implementing new asphalt grooving trial sections. This innovative technique aims to mitigate hydroplaning risks, increase pavement durability and provide a safer driving experience.   The state is actively seeking alternatives to Open Graded Asphalt Friction Course (OGFC) due to long-term durability concerns. Safety grooving presents an

The role of DOTs in pavement friction management For decision-makers at departments of transportation (DOTs), managing pavement friction is a critical mandate. Ensuring that road surfaces maintain adequate friction directly impacts crash prevention, infrastructure durability and effective resource allocation. By leveraging advanced friction metrics, DOTs can accurately identify high-risk areas and deploy targeted safety interventions. This proactive, data-driven approach maxi

New report explores the latest findings on safety, durability and performance The Airport Concrete Pavement Technology Program  (ACPTP) and the National Concrete Pavement Technology (CP Tech) Center  have released a new report, " Effects of Diamond Grinding on Airfield Concrete Pavements. "  Sponsored by the Federal Aviation Administration (FAA), the report addresses industry concerns regarding restrictive specifications, surface durability and long-term performance. Why diam

A recent pavement preservation project on I-70 in Montgomery County, Missouri, highlights how innovative engineering can enhance roadway safety while delivering significant cost savings. Selected as the project contractor by the Missouri Department of Transportation  (MoDOT), IGGA member Emery Sapp & Sons (ESS) sought a solution that would meet the rigorous safety demands of a high-speed interstate while maximizing the efficiency of their preservation budget. The project’s or

How it works and why it matters The first decade of the 2000s marked a pivotal moment in pavement engineering with the introduction of the Next Generation Concrete Surface (NGCS) . Developed through a robust collaboration between the IGGA, A merican Concrete Pavement Association, Portland Cement Association, Purdue University and the  Minnesota DOT,  this innovation was engineered specifically to address tire-pavement noise. Unlike traditional surfaces that rely on random tex

High agency engineer turnover has resulted in a knowledge gap regarding current roadway repair techniques and tools. Continuing education is, therefore, essential to ensuring best practices are understood and applied to highway projects.  In 2026, the IGGA is traveling the U.S. to educate engineers on concrete pavement repair best practices and highway surface texture remediation. We have already hosted two successful sessions this year in Dallas/Ft. Worth and Colorado, and

A 2002 study titled " The Long-Term Performance of Unsealed Jointed Concrete Pavements " evaluated the efficacy of unsealed pavement joints against those maintained with high-quality sealant materials. The primary objective was to observe performance over extended periods rather than relying on short-term snapshots.   Today, these findings remain critical for contractors and agency specifiers. As the industry faces increasing pressure to maximize infrastructure lifecycles, un

From CSA as a game-changer to common misconceptions to future priorities and more The IGGA’s John Roberts and Nick Davis were busy at this year’s World of Concrete (WOC), from connecting with members and visitors at our booth to stopping by members' exhibits to hosting the IGGA reception and more. Somehow, they found the time to sit down for several interviews—sharing important insights into industry advancements, trends in pavement preservation and concrete infrastructure, t

A combination of diamond grinding and concrete pavement rehabilitation (CPR) can significantly extend a pavement's service life Maintaining aging infrastructure on high-traffic corridors is a critical challenge for transportation departments. The Minnesota Department of Transportation (MnDOT)  faced this issue on US Highway 12, a vital route with aging concrete pavement, drainage problems and outdated pedestrian accessibility features. To address this, MnDOT implemented a com
