A brief review is presented of the newly revised edition of The Asphalt Institute airfield pavement design manual, Full-Depth Asphalt Pavements for Air Carrier Airports (MS-11). A new design procedure predicated upon multilayered elastic concepts is introduced. The method is based on the necessity for designing against two types of pavement distress: (1) Cracking in the asphalt layer due to fatigue; and (2) excessive deformation due to overstressing the subgrade. The design procedure is briefly described. The design method is based on the theory that a full-depth asphalt pavement is a multilayered elastic system and that the application of load to the pavement produces two critical elastic strains: (1)Horizontal tensile strain at the bottom of the asphalt concrete layer; and (2) vertical compressive strain at the top of the subgrade layer. Design criteria based on maximum allowable values for the strains are used in developing the design procedure. Influence and effects of materials and environmental factors are examined.
