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 …

Analysis of Factors Affecting Pavement Markings and Pavement Marking Retroreflectivity in Tennessee Highways
Pavement markings are lines drawn on a pavement surface to provide vital information to road users pertaining to lane restrictions and vehicle movements, which if adhered to, results in improved safety and smooth travelling to road users. Pavement markings’ visibility is quantified into a parameter …
