Interface shear fatigue performance of asphalt pavement structures in function of normal stress and temperature

2T3C HCA, a new hollow cylinder device using Digital Image Correlation to measure properties of interfaces between asphalt layers

“…The influence of factors such as temperature [17], normal stress application [10], nature and dosage of tack coat [18] have been investigated. Several shear tests are used to assess interface fatigue properties under cyclic shear loadings [2,[19][20][21][22] in order to obtain the fatigue law of interfaces for different test conditions or different materials. All these shear tests are inhomogeneous: the shear stress is not uniform at the interface.…”
