TRB will conduct a webinar on Thursday, August 17, 2017 from 2:00 PM to 3:30 PM ET that features research from the National Cooperative Highway Research Program (NCHRP)’s Synthesis 500: Control of Concrete Cracking in Bridges.

This webinar will examine the methods used to control concrete cracking in bridge superstructures and substructures and on the influence of cracking on long-term durability. The control of cracking for aesthetic, durability, and structural reasons becomes increasingly important as service-life goals are extended and higher-strength concrete, higher-strength reinforcement, and different types of reinforcement are used in bridge construction.

Some registrants will need to pay a fee to attend this webinar. Sign into MyTRB.org to view registration information.
