Determination of threshold of asphalt pavement structure crack damage rate to quantify the severity of structural crack damage
Cracks in asphalt pavement are typically identified by analyzing electromagnetic or mechanical wave propagation. Validation is done by examining core samples obtained through drilling. This study proposes a threshold based on the structure crack damage rate (SCDR) collected by ground-penetrating radar (GPR) to quantify the severity of structure cracks. The Fuzzy c-means (FCM) algorithm categorises SCDR into different severity levels. Results indicate clear separation among most data points, but some overlap exists, particularly between non-structural and low-structural damage, and low-structural and medium-structural damage. High-structural damage areas are consistently distinct. The most successful outcomes are achieved when dividing structural crack damage levels into three groups. Thresholds for crack damage rates are ultimately determined to be 0.1909% to differentiate between non-structural and low-structural damage, and 0.6632% to differentiate between low-structural and high-structural damage. These findings serve as a foundation for assessing asphalt pavement crack damage and guiding maintenance decisions.
