Call for Presentation Abstracts for Centennial Meeting of the Association of Asphalt Paving Technologists (AAPT)

 

In preparation for the Centennial Anniversary of the AAPT, the AAPT is having a call for presentation abstracts on a broad range of topics based on the responses from the Membership survey.  To apply to be a presenter at the Centennial Meeting, AAPT is requesting the submittal of an abstract (500 words or less) that best describes the content of the presentation.  The presentation timeslot is scheduled to be 30 minutes – 20 minutes for presentation content and 10 minutes for questions/comments.  In addition to the abstract, a bulletized summary of the presenter’s experience pertaining directly to the selected topic is required to show competence of the topic.  Please note this is specifically a call for presentations – a call for papers will be advertised for the 2025 annual meeting as traditionally conducted by the AAPT.
You can submit your abstract via this link: https://unh.az1.qualtrics.com/jfe/form/SV_9o5YeArPoJ9M9lI
The deadline for submittal is March 31, 2024
Presentation topics and conceptual ideas requested for the meeting are noted below.  However, additional topics will be considered if found applicable.  Please note whether you are interested in participating as - Podium Only; Poster Only; Both
