Two significant advances have recently emerged in predicting the in-place strength of concrete for pavements and facilitating earlier opening of pavements. The first is the development of a new American Association of State Highway and Transportation Officials (AASHTO) maturity test method for pavements. The second is ASTM C1074, an advancement in sensor technology, which captures time and temperature data from the field. TRB hosted a webinar on Wednesday, October 9, 2024 from 11:00 AM to 12:30 PM Eastern that informed agencies and practitioners of these new approaches. Presenters shared a case study from Iowa Department of Transportation (DOT) and how they utilized the maturity concept for determining early opening strengths for the past 25 years.
This webinar was a follow on to the 2024 TRB Annual Meeting Session 2125: Pavement Opening Strength: Why Not Maturity?
This webinar was sponsored by TRB’s Standing Technical Committee on Concrete Pavement Construction and Rehabilitation.
The slides are available. Please contact trbwebinar@nas.edu for a link to the recording. There may be a $90 fee.
