TRB conducted a webinar on October 27, 2014, from 2:00pm to 4:00pm ET that presented findings associated with field experiments in order to quantify energy savings, plant emissions, and health impacts to paving crews for warm mix asphalt (WMA) compared to hot mix asphalt (HMA). This webinar was the second of a two-part series highlighting the research and findings of
NCHRP Report 779: Field Performance of Warm Mix Asphalt Technologies. The first webinar in the series,
Engineering Properties and Field Performance of Warm Mix Asphalt, was held on October 14, 2014 from 2:00pm to 4:00pm ET.
A certificate for two Professional Development Hours (PDHs) was provided to attendees who registered and attended the webinar as an individual. Contact Reggie Gillum at
RGillum@nas.edu for information on obtaining the webinar recording.

- Randy West, National Center for Asphalt Technology (NCAT)
- Brian Prowell, Advanced Materials Services, LLC
- Linda Osborn, Heritage Research Group
- Bob Frank, Compliance Monitoring & RAP Technologies
Moderated by: Ed Harrigan,
Transportation Research Board
Webinar Outline
- PART 1: Background and plant fuel savings
- PART 2: Stack emissions
- PART 3: Worker exposure
- PART 4: Summary of findings
- PART 5: Question and answer session
The first 90 minutes of the webinar will be for presentations and the final 30 minutes will be reserved for audience questions. The Registered Continuing Education Program (RCEP) categorizes this webinar activity as relating to health, safety, and welfare including core technical.
Learning Objectives
At the end of this webinar, participants will be able to:
- Describe the relationship between the energy used to produce asphalt paving mixtures and mix temperatures;
- Summarize other variables that significantly impact the energy necessary to produce asphalt paving mixtures;
- Describe the relationship between fuel usage and carbon dioxide emissions at an asphalt plant;
- Summarize other variables that affect the quantity of gaseous emissions during asphalt mixture production; and
- Explain the general health and environmental benefits associated with WMA.
