A METHOD BASED ON THE AASHO ROAD TEST MODEL EQUATION AND A THEORETICAL EQUATION FOR PAVEMENT DEFLECTION IS PRESENTED FOR DESIGN OF FLEXIBLE PAVEMENTS IN VIRGINIA. THE INDEPEND- ENT VARIABLES EVALUATED ARE (A) THE THICKNESS OF THE LAYERS OF THE PAVEMENT, (B) STRENGTH EQUIVALENCIES OF THE MATERIALS IN EACH LAYER OF THE PAVEMENT, (C) SUBGRADE SUPPORT VALUE INCLUDING THE SOIL RESILIENCY AND THE ENVIRONMENTAL CONDITIONS AFFECTING IT, AND (D) TRAFFIC. THE DEPENDENT VARIABLE IS THE DEFLECTIONS MEASURED BY DYNAFLECT IN THE SPRING OF 1967 AND 1968. THICKNESS EQUIVALENCIES OF THE MATERIALS USED IN THE CONSTRUCTION OF FLEXIBLE PAVEMENTS IN VIRGINIA HAVE BEEN DETERMINED. A SOIL CLASSIFICATION MAP OF VIRGINIA, BASED ON ABOUT 200 PROJECTS (EACH WITH 2 TO 30 SOIL SAMPLES) THROUGHOUT THE STATES, HAS BEEN PREPARED. THIS MAP SHOWS FIVE SOIL CLASSIFICATIONS BASED ON RESILIENCY, THE AASHO SOIL CLASSIFICATION, AND TEXTURE OF THE SOILS. A DESIGN METHOD FOR VIRGINIA IN THE FORM OF A NOMOGRAM IS PROPOSED AS A MAINTENANCE AND DESIGN TOOL. TWO ADDITIONAL METHODS ARE BASED ON PRESENT DESIGN CONCEPTIONS, STANDARDS, AND PRACTICE IN VIRGINIA. /AUTHOR/
