| dc.description.abstract | This study aimed to evaluate the asphalt mixtures used in New Brunswick to establish thresholds as a significant step toward adopting the Balanced Mix Design (BMD) approach. For this purpose, asphalt cores were extracted from six in-service pavement sections in the province. Additionally, two widely used mixtures in New Brunswick were produced and compacted in the laboratory. The Tensile Strength Ratio (TSR) test was conducted to evaluate the moisture susceptibility of the laboratory-prepared specimens. To assess the rutting potential of both cored and laboratory mixes at high temperatures, the Rapid Shear Rutting Test (Ideal RT) test and Hamburg Wheel Track Test (HWTT) test were utilized. The Indirect Tensile Asphalt Cracking Test (Ideal CT) test and Semicircular Bend (SCB) test were employed to investigate the fracture performance of mixes at intermediate and low temperatures, respectively. Finally, using road survey data collected by (Automatic Road Analyzer) ARAN, final thresholds were determined as acceptance criteria for the province of New Brunswick. | |
