The American Concrete Pavement Association's Emerging Leaders Group, led by IGGA’ Nsick Davis, hosted its first-ever Spring Leadership Training last week and it was a great success. The professionally facilitated training opportunity, designed for young professionals and emerging leaders, covered a variety of topics including results-oriented communication, mental health and wellbeing, emerging industry technologies and more.

At the 2025 World of Concrete, IGGA’s Nick Davis presented several critical concrete preservation methods, including dowel bar retrofit. Nick kicked off the presentation with a discussion about the role dowel bar retrofit plays in helping improve a pavement’s structural integrity.

Did you know? Concrete pavement compression seals, which do not require field heating, mixing or curing, were introduced in the 1960s. Some of the earliest installations were made with oil soap. Eventually, a neoprene-based adhesive was selected. Adding the adhesive provides additional bonding to and filling the surface irregularities on the joint face.

A section of a roadway in Cornwall has become one of the first in the UK to trial a new grade of concrete that reduces road noise. The technique, trialed by Tarmac, has successfully reduced noise by up to seven decibels. In a single-pass process treatment, grooves are created into the existing concrete pavement while grinding is applied to add texture and improved skid resistance.? According to Nick Knorr, head of National Highways' National Concrete Roads Programme, this new approach is part of Tarmac’s Next Generation Concrete Solutions (NGCS) portfolio, and is considered “a promising technique and we have seen positive results related to noise reduction and ride quality.” Read the Global Highways Magazine article to learn more: https://ow.ly/51of50Vagev

IGGA Director of Technical Services Nick Davis attended the The National Academies of Sciences, Engineering, and Medicine 104th annual Transportation Research Board conference in Washington D.C. last month, with over 13,000 transportation researchers and practitioners in attendance. This event offered unparalleled networking opportunities for key target markets of the IGGA. We will pursue these new relationships to continue growing the work opportunities for our manufacturers, suppliers, consultants and contractors. https://ow.ly/Q4aq50UVewW

After over 60 years of service, it was determined that the Delaware Memorial Bridge needed a major deck rehabilitation. A Green Building and Design Magazine article explained the work required installing a high-performing deck without adding more weight to the structure. Ultra-High Performance Concrete (UHPC) was installed on this project, which was diamond ground and grooved to ensure a smooth riding surface. The project resulted in a more durable, resilient and smooth bridge deck with “a low financial impact” and reduced CO2. Read more: https://ow.ly/Gano50UVcI4 #concretepreservation

While?tire noise is still an issue in 2025, the roadway construction industry is making it less of a concern compared to previous years, thanks to advancements like Next Generation Concrete Surface (NGCS). Extrica’s Journal of Vibroengineering referenced NGCS in a review of tire-pavement noise and reduction approaches (https://ow.ly/eSwq50UVbZ4). They concluded NGCS is a “consistent, predictable, and quiet, nonporous concrete texture with good lateral stability and hydroplaning resistance.” Learn more about NGCS here: https://ow.ly/ZRsP50UVbZ5

Spray sealers are a useful tool in concrete pavement preservation (#CPP) due to their roles in extending the lifespan and maintaining the integrity of concrete surfaces. Penetrating sealers can keep water out through a variety of mechanisms, including acting as a water repellent, densifying the surface, blocking pores and more. Sealers make it difficult for water to penetrate, while still permitting water vapor to escape, allowing the concrete to dry out. This process helps maintain the structural integrity and appearance of concrete surfaces over time. Learn more here: https://ow.ly/fFMv50UVbmS

At last month’s World of Concrete, IGGA’s Nick Davis discussed several critical concrete preservation methods, including dowel bar retrofit (#DBR). DBR is a proven technique that addresses a common #pavement distress—slab faulting. By adding a mechanical load transfer device into joints of pavements, engineers can ensure the slab will not fault again in the future after ride quality improvements are made with diamond grinding.

The IGGA truly showed how to "get our groove on" during our disco reception at the World of Concrete. From moving to the funky beats of the 70s, sipping on delightful drinks and savoring scrumptious snacks to engaging in spirited conversations while making connections, the evening was a hit with everyone in attendance. With every laugh and shared story, the sense of community blossomed, reminding us all that when we come together, we can create a solid foundation for success. https://ow.ly/P2A450UYvZF
