Using the AASHTO procedure, determine the thickness required for a base and a surface layer over existing subgrade. The structural number required for this pavement is 4.5. The available materials are a crushed stone base course with a material layer coefficient of 0.13 and an HMA surface with a material layer coefficient of 0.40. The drainage coefficient of the based course can be considered as 0.90.
