Title: SPTC - ODOT Workshop on: Effect of WMA and Anti-Stripping Additives on PPA-Modified Binders

Friday, June 30th, 8:30-10:00 AM
ODOT Commission Room, 200 NE 21st St, Oklahoma City, OK 73105

Presenter: Rouzbeh Ghabchi, Musharraf Zaman, and Shivani Rani

ABSTRACT: Enhancing the high-temperature PG grade of asphalt binders by using Polyphosphoric Acid (PPA) is becoming more popular due to its lower cost, compared to polymer modification. Despite its benefits, long-term performance and moisture-induced damage are major concerns associated with adding PPA to asphalt binders. The purpose of this workshop is to present the outcomes of the research conducted at the University of Oklahoma to evaluate the effect of PPA on rheology and moisture-induced damage potential of asphalt binders. The presentation will be followed by questions and discussion.

Attendees will earn 1.5 professional development hours (PDHs). You must register with your own email to receive your PDH.

Title: SPTC - ODOT Workshop on: Applicability of MSCR Grading of Polymer- and RAP-Modified Binders

Friday, June 30th, 10:15-11:45 AM
ODOT Commission Room, 200 NE 21st St, Oklahoma City, OK 73105

Presenter: Rouzbeh Ghabchi, Musharraf Zaman, and Shivani Rani

ABSTRACT: Multiple Stress Creep Recovery (MSCR) is a relatively new test method and is proposed to replace the Superpave® performance grade (PG) and PG plus tests. The aim of the workshop is to introduce the MSCR test method and specifications and to compare the results of the Superpave® and MSCR tests conducted on Oklahoma binders. The work-shop will be followed by questions and discussion.

Attendees will earn 1.5 professional development hours (PDHs). You must register with your own email to receive your PDH.
