On Cross-Anisotropy of Flexible Pavement Layer Materials for Improved Pavement Responses
<p>Pavement layer materials are typically assumed to be isotropic in determining pavement responses, such as stress and strain. The main benefit of the isotropic assumption is that stiffness defined by modulus of elasticity (E-value) is equal in all directions. In reality, stiffness along vertical …
