• Abstract:
  The objective of this study is to evaluate the influence of asphalt binders possessing the same Performance Grade (PG) but differing in chemical composition as characterized by SARA fraction percentages on the mechanical performance of asphalt mixtures across high, intermediate, and low temperatures. Two sets of laboratory experiments will be conducted: (1) asphalt binder characterization and (2) asphalt mixture performance testing. The asphalt binder characterization will include PG grading, Gel Permeation Chromatography (GPC), and SARA fractionation analysis. The asphalt mixture testing will include a comprehensive suite of laboratory mechanical performance tests: Semi-Circular Bend (SCB) and IDEAL-CT tests for fracture and fatigue resistance; Loaded Wheel Tracking (LWT) and IDEAL-RT tests for rutting resistance; SCB test for low-temperature cracking performance; and the Cantabro test for durability assessment.
