| Abstract: | It is important to obtain the strain of asphalt mixture sample in the indirect tension mode in order to study its damage mechanism. As a result, aiming at the research on the strain of asphalt mixture sample in indirect mode, the digital image correlation method (DICM) was used to obtain the indirect tension strain at the loading peak time. Then, the results between the measured and strain gage methods are compared and analyzed. The results show that DICM is available to study the indirect tension stain. |
