Details


Determining accurate asphalt content of mixtures is critical, particularly as the quantity of recycled materials allowed during production increases. TRB will host a webinar on Wednesday, February 28, 2024 from 11:00 AM to 12:30 AM Eastern that will present the work conducted by NCHRP to revise the current AASHTO T 308 test procedure to be able to incorporate mixes with high recycled materials content. Presenters will explore the effect of reducing the test temperature from 1,000 degrees Fahrenheit to 800 degrees Fahrenheit. Presenters will also share a new precision statement of the AASHTO procedure including recycle mixes.
This webinar is based on NCHRP Research Report 1060: Ignition Furnace Correction Factors: Identifying Influences and Minimizing Variability.
This webinar is sponsored by TRB’s National Cooperative Highway Research Program.
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 MyTRB.org 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.
