Details

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 hosted a webinar on Monday, February 6, 2023 from 2:00 PM to 3:30 PM Eastern that presented the practices used by state departments of transportation (DOTs) to evaluate the smoothness of newly constructed bridge decks. Presenters identified 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 was sponsored by TRB’s National Highway Cooperative Research Program and the Standing Technical Committee on Pavement Surface Properties and Vehicle Interaction.

The slides and recording are available.
