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? Find out at intrans.iastate.edu/app/uplo… and intrans.iastate.edu/app/uplo… #ConcretePaving

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

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 cptechcenter.org/cementitiou… #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-an… #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/uplo… and several videos at cptechcenter.org/webinars-an… address this—check them out! #ConcretePavement #ConcreteDistress

"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-tec… #QualityRoads #ConcretePaving #InfrastructureBill

CP Tech Center publishes Quality Control for Concrete Paving guide | Institute for Transportation

“What gets measured gets managed” is a common adage in quality management. Thus, the core of every successful quality control (QC) program for contractors and material suppliers is monitoring key…

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

Internal Curing | National Concrete Pavement Technology Center

Insufficient curing is frequently reported as causing early-age concrete pavement and bridge deck deterioration, posing safety and maintenance issues that cost agencies time and money.

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
