High-Speed Photography of Asphalt Cracking

Cracking in asphalt occurs mainly due to repeated traffic loadings and temperature fluctuations. To prevent propagating cracks and to reduce unwanted rehabilitation and maintenance costs, understanding crack characteristics of an asphalt mix is of critical importance in many pavement designs. Using the indirect tensile splitting test, also known as the IDT method, this study aims to evaluate the crack propagation pattern in several asphalt mixes...
