If the "just add water" approach to addressing workability problems is a recipe for DECREASED concrete strength😲and INCREASED segregation, permeability, and bleeding😣, what other options exist?

The first in-person National Concrete Consortium (NC²) meeting since COVID = professional engineers from agencies, industry, and academia brainstorming together to solve real-world concrete paving challenges. What concrete paving questions will YOU ask at NC²? #ConcretePaving

Need help with the 2011 Public Access Right-of-Way Guidelines (PROWAG)? 👩‍🦽👨‍🦯👩‍🦽 View the CP Tech Center's Americans with Disabilities Act (ADA) webinar series by Jesse Jonas and @jackie_spoor at cptechcenter.org/webinars-and-v… and cptechcenter.org/webinars-and-v… #ConcretePaving #Accessibility

Can you tell which SEM pic is harvested vs. freshly produced fly ash? 🤔 There's a reason. . . . Harvested fly ash has been demonstrated to match the chemical and physical properties of freshly produced fly ash😮 Learn more at #FlyAsh" target="_blank" rel="nofollow noopener">cptechcenter.org/cementitious-m… #ConcretePavement

Is your agency maximizing pavement condition AND minimizing life-cycle costs by taking advantage of not only ➕ADDITION➕ (i.e., overlay) but also ➖SUBTRACTION➖(i.e., diamond grinding/NGCS) concrete pavement preservation strategies? #ConcretePaving #ConcreteBridges #Tunnels

Resilient pavement systems are no longer a luxury—they are a necessity. To safeguard the impact of their infrastructure bill investments, transportation departments MUST prioritize pavement resilience. Learn more at cptechcenter.org/webinars-and-v… #ConcretePavement

According to Ben Franklin, an ounce of prevention is worth a pound of cure. How then do we prevent—or at least mitigate ASR? Our 2020 MAP brief intrans.iastate.edu/app/uploads/20… and several videos at #library" target="_blank" rel="nofollow noopener">cptechcenter.org/webinars-and-v… address this—check them out! #ConcretePavement #ConcreteDistress

The CP Tech Center’s concrete mixture proportioning spreadsheet calculator can lower cement content requirements so reduce CO₂ impact while maintaining or improving mixtures—find it at cptechcenter.org/mix-proportion… #ConcretePavement #PerformanceEngineeredMixtures #Sustainability

"What gets measured gets managed." The CP Tech Center has just published a new guide on "Quality Control for Concrete Paving." Learn more at cptechcenter.org/news/cp-tech-c… #QualityRoads #ConcretePaving #InfrastructureBill

Learn more about internal curing at: cptechcenter.org/internal-curin…

Has YOUR state tested internal curing to reduce bridge deck cracking? When lightweight fine aggregate (LWFA) serves as a reservoir for prolonged hydration, no increased w/cm ratio is usually required to reduce differential volume change during hydration🔎💧🔎 #Concrete #Bridges

As virgin resources have decreased, quality aggregate demand has increased = Recycled concrete aggregate (RCA) is good not only for sustainability but also for agencies' bottom line Please share money-saving RCA project pics 😮 #ConcretePavement #ConcreteRocks #Sustainability

Most quotable quote on the CP-Tech-Center-organized 2021 Iowa Better Concrete Conference: "I got more done here in one day than in a normal week because everyone is here" (@mulder4cy). The BEST concrete comes from agency, academia, association, and industry give-and-take!

For any given concrete mixture, how do you decide how much vibration is too much, too little, or just right? What pic would you recommend for training new concrete paving crew members about the importance of not overvibrating or undervibrating fresh concrete? #concrete

What benefits might an added concrete walking/biking trail provide your community? Learn how to make your vision a reality via the CP Tech Center’s “Guide to Concrete Trails” at cptechcenter.org/research/compl… #Trails #RailsToTrails #ActiveTransportation

This is the first Tuesday in 11 weeks without a webinar. Thanks to @PaveConcrete for helping us reach 7500 people in that time. See you all again in July!

Another group learning the fine art of building concrete pavements from yhe master!
