Flexible pavements, in which bituminous bound materials are placed over granular base and sub-base layers and supported by subgrade. The load is absorbed and distributed with depth. • Rigid pavements, in which a concrete layer is placed over a subgrade with or without a sub-base layer. The rigid slab spreads the load over a large area.

reinforcement layer is usually placed between the sub-base and sub grade interface or between the base course and sub-base. Due to the wide application of this technique, many experimental and analytical studies have been conducted to assess and potentially quantify the improvements associated with geogrid base reinforcement of roadways.

A list of layer coefficients is proposed for pavement design. The results of the asphalt materials did not show that there are significant differences in resilient modulus of asphalt mixtures tested; thus, layer coefficients for the asphalt mixtures, derived : based on the resilient modulus, are similar for all asphalt mixtures.
Therefore, the pavement structure must be selected based on the construction traffic and sequence of construction. These pavements are generally built in phases. The first phase is the laying of the aggregate sub-base and asphalt base layers on the prepared subgrade or laying an asphalt base layer directly on the prepared subgrade.
