AI Technical Summary
Existing semi-circular bending (SCB) test systems for fracture analysis of bituminous mixtures are complex, expensive, and require advanced technical expertise, making them difficult to access and prone to inaccuracies, especially when assessing the fracture toughness of quasi-brittle materials like asphalt concrete, which exhibit elasto-plastic behavior.
A novel SCB test system utilizing simple, low-cost equipment and compliance-based analysis to determine fracture toughness of asphalt concrete using the Effective Crack Model, enabling fracture mechanics-based evaluation of notched specimens at both low and ambient temperatures.
Facilitates accurate and cost-effective determination of fracture toughness parameters for asphalt concrete, supporting reliable pavement design in earthquake-prone regions, particularly during severe winter conditions.
