Finite element cohesive fracture modeling of asphalt mixture based on the semi-circular bending (SCB) test and self-affine fractal cracks at low temperatures
Abstract
<p>Thermal cracking is one of the most common distresses for asphalt pavement constructed in the cold regions. In order to address this issue, the combined use of fracture mechanics-based tests and simulation is a solid option. First, asphalt mixture samples are prepared based on the German standard and the low temperature strength are measured by Semi-Circular Bending (SCB) test and the Uniaxial Creep (UC) test at three different temperatures: −6, −12 and −18 °C. Next, experimental test results are used to perform the cohesive zone (CZ) modeling by using a two-dimensional finite element (FE) simulation. As a new approach, the CZ is modeled along a self-affine crack path, which allows performing a simulation closer to reality. The FE results provide a comprehensive understanding of the mechanism of crack initiation and propagation while keeping the computational time within a reasonable level.</p>
