The Transportation Research Board (TRB) will conduct a Webinar on Thursday, May 1, from 2 to 4 p.m. Eastern time that will introduce the concepts of internal curing of concrete and provide information on its implementation in transportation structures and pavements. Internal curing is an emerging technology used to increase the service life of concrete and reduce cracking and chloride ingress. Participants must register before the Webinar and there is a fee for non-TRB Sponsor or non-TRB Sustaining Affiliate employees. A certificate for two Professional Development Hours (PDHs) will be provided to attendees who register and attend the Webinar as an individual.
