Methods are suggested for material selection, moisture control, and compaction or treatment of soils and materials to assure volume stability and uniform support for concrete pavements. Various environments are considered and appropriate methods of subgrade preparation are outlined. Subbase functions are defined and adaptability of types of subbases are discussed. Placement of materials to aid in subbase moisture control is emphasized in shoulder design. A section on recognition of causes of deficiencies in existing pavements is included to alert the engineer to the consequences of improper construction or adverse environment.
