This paper is the outcome of a specific task group of the RILEM Technical Committee 241-MCD "Mechanisms of Cracking and Debonding in Asphalt and Composite Pavements". The group on "Advanced Measurement Techniques" was established in 2011 to investigate DIC applications for non-destructive and non-contact measurements of strain fields during laboratory testing. The paper illustrates different DIC/optical flow applications in measuring strain distribution during laboratory testing. Specific applications of DIC for evaluating crack initiation and crack propagation in asphalt materials are presented
