Optimizing Concrete Pavement Opening to Traffic


Recent research has determined that conventional wisdom of designing concrete mixes for very high early strengths to open the pavement to traffic early may not be the best approach. Typically, high early strength mixes contain additional cement in order to obtain design strength faster, but end up with a 28 day strength much higher than design. This additional cement not only increases initial cost but more importantly, may reduce long term durability. The Concrete Pavement Technology Center recently published a technical summary entitled ‘Optimizing Concrete Pavement Opening to Traffic’ which examines these considerations and suggests that a much better approach may be to redefine our opening to traffic strengths to something much lower than what we are using today.

Excellence in Concrete Pavement Awards

Congratulations to our ACPA National Award winners! Two Oklahoma projects brought home the Gold from this year’s American Concrete Pavement Association Excellence in Concrete Pavements awards. The awards program encourages high-quality workmanship in every concrete pavement project and serves as a forum for sharing information about highly successful projects.

Choosing Equivalent Pavement Designs

Life-cycle costs are an increasingly important decision point in the selection of pavement materials. Life-cycle cost analysis (LCCA) requires careful consideration of the complete costs over time – not only the cost to construct the pavement system, but the cost to keep it in good condition over time.

Arkansas Concrete Pavement Conference

The 2023 Arkansas Concrete Pavement Conference held in Hot Springs, AR this past week was a huge success with over 130 transportation professionals in attendance. ARDOT Director, Lorie Tudor, opened the session with a thorough presentation on ARDOT activities both present and future. FHWA Division Administator Vivien Hoang and ACPA President and CEO Laura O’Neill Kkaumo rounded out the morning giving overviews of their respective operations before the technical sessions kicked into gear. The weather was hot but the air conditioning was cold and the food was good. The OK/AR Chapter, ACPA would like to thank the speakers, exhibitors and sponsors for helping make this conference such a success. See you all next year!
