Attention to details in the volumetric acceptance process is important to ensure an asphalt mixture with adequate asphalt content. These details apply to the mixture design and acceptance. TRB hosted a webinar on Monday, October 30, 2023 from 1:00 PM to 2:30 PM Eastern that shared key properties that need to be included in the design and acceptance of asphalt mixtures. Presenters shared how to strengthen quality assurance programs in the design and acceptance of asphalt mixtures.

This webinar was sponsored by TRB’s Standing Technical Committees on Asphalt Materials Selection and Mix Design, Production and Use of Asphalt, and Aggregates.

The slides are available. Please contact for a link to the recording. There may be a $90 fee.
