摘要
In order to study the damage mechanism of asphalt mixture,it is important to obtain the distribution of displacement and strain of its sample in the indirect tension mode.As a result,the digital image correlation method (DICM) was used to evaluate the displacement field and strain field of asphalt mixture.The results showed that the displacement fields under DICM and ABAQUS are similarly;the strain fields are different due to the different modulus of mastic and aggregate;and DICM is an practical method to study the indirect tension displacement and stain.

The results showed that the displacement fields under DICM and ABAQUS are similarly; the strain fields are different due to the different modulus of mastic and aggregate ; and DICM is an practical method to study the irldirect tension displacement and stain.
