TRB Webinar: Evaluating the Smoothness of Newly Constructed Concrete Bridge Decks

Bridges can provide a lower ride quality when compared to pavements. To provide a good ride quality, attention should be paid to constructing smooth bridge decks. TRB will host a webinar on Monday, February 6, 2023 from 2:00 PM to 3:30 PM Eastern that will present the practices used by state departments of transportation (DOTs) to evaluate the smoothness of newly constructed bridge decks. Presenters will identify the equipment used to measure the smoothness, the method or index to measure the smoothness, and the smoothness thresholds contractors are required to achieve.

This webinar is based on NCHRP Synthesis Report 580: Practices for Ensuring the Smoothness of Concrete Bridge Decks.

This webinar is sponsored by TRB’s National Highway Cooperative Research Program and the Standing Technical Committee on Pavement Surface Properties and Vehicle Interaction.

Registration is free for employees of TRB sponsors as well as Titanium and Cobalt Global Affiliates. The registration rate for all other attendees is $100. Sign into to view registration information. Contact Patrice Davenport to inquire about becoming a TRB sponsor or global affiliate organization.

A recording will be sent to all registrants after the webinar.
