Sub-Base course is the layer (or layers) under the base layer. A sub-base is not always needed. A proper sub-base consists of various sizes of crushed stone aggregate, commonly known as crusher run. Depending on the sub soils on your site you may need 8-12 inches of various sizes of sub-base. With well drained sub soils, without movement, added sub-base materials may be sufficient, along with

The sub-base layer enhances the bearing capacity of the sub grade and improves the load distribution capacity of the base course and wearing course. The sub base course prevents the entry of finely graded sub grade soil to the base course layer. They prevents the capillary rise of water and enables free drainage of water entering the pavement. The sub base material must be free draining for
