Investigating The Use Of 100% Rap In Airfield Mixtures For Contingency Pavement Repair In Remote Regions, Mahmoud Samara

Theses and Dissertations

The goal of this study was to present a procedure for performance-related mix design of 100% recycled asphalt pavement (RAP) mixtures used in repair applications. In addition, the impact of rejuvenators (Corn Oil, Tall Oil, Modified Vegetable Oil, and Aromatic Extract) on the RAP materials' properties were also investigated on both levels (binder, and mixtures). Performance grade testing, frequency sweep test, critical temperature differential (delta Tc), and Fourier Transform Infrared Spectroscopy (FTIR) tests were conducted to evaluate the rheological and chemical properties of extracted and rejuvenated RAP binders. Afterward, asphalt pavement analyzer (APA) and indirect tensile asphalt cracking (IDEAL-CT) tests …
