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 outlined. Base and subbase functions are defined and adaptability of types of subbases discussed. Placement of materials to aid in subbase moisture control was emphasized in shoulder design. References to pertinent technical manuals and articles are made throughout and AASHO and ASTM standard methods and tests are keyed where appropriate. 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.
