ABSTRACT
ABSTRACT: The Pavement structure is a multi-layer system which is designed to distribute and transfer loads on the top of subgrade. The used materials and thickness of the pavement is designed aiming fulfilling two main objectives: 1-Decreasing the intensity of vertical pressure to a level suitable for subgrade, and 2-Reducing tensile stresses on the lower layer of the subgrade to lower than admissible tensile stress of subgrade to avoid tensile crakding on the top of this layer.
