DESIGN AND CONSTRUCTION OF SUBBASES AND FOUNDATIONS FOR PAVEMENTS

This report describes the physical requirements of the five most commonly used subbase materials and suggests how these materials may be used most effectively for varying traffic conditions. Minimum thicknesses of subbases for both rigid and flexible pavements are obtained by use of a combination K-values, potential vertical rise, and conventional pavement thickness design methods. The problem of treating soils that have high volume changes at great depths is discussed, and its solution is used to remedy the subbase problem. Examples for both rigid and flexible pavements are presented, as is a procedure for determining the desired moisture contents of swelling soils at various depths below the pavement.
