EVALUATION OF AASHO INTERIM GUIDES FOR DESIGN OF PAVEMENT STRUCTURES
THIS PROJECT CAN BE CONSIDERED TO BE PART OF THE CONTINUING PROCESS OF UPDATING AND IMPROVING DESIGN PROCEDURES OF FLEXIBLE, RIGID, AND OVERLAY PAVEMENTS. FROM THE STUDY OF CURRENT HIGHWAY PRACTICES, AND WITH CONSIDERATION OF RECENT DEVELOPMENTS IN ANALYTICAL DESIGN THEORIES AND METHODS OF CHARACTERIZING PROPERTIES OF PAVEMENT MATERIALS, IT WAS FOUND CONVENIENT TO SUMMARIZE THE INFORMATION IN SIX BROAD CATEGORIES: EXTENT OF USE OF THE INTERIM GUIDES; TRAFFIC; FLEXIBLE PAVEMENT DESIGN, INCLUDING SOIL SUPPORT, REGIONAL FACTORS, AND STRUCTURAL LAYER COEFFICIENTS; RIGID PAVEMENT DESIGN; OVERLAY DESIGN PROCEDURES; AND CURRENT RESEARCH. A SIGNIFICANCE STUDY WAS CONDUCTED USING THE DESIGN RPOCEDURES IN THE GUIDES FOR BOTH RIGID AND FLEXIBLE PAVEMENTS IN ORDER TO DETERMINE THE RELATIVE INFLUENCES OF EACH OF THE VARIABLES. ALSO OUTLINED WAS THE IDEALIZED DESIGN PROCEDURE AS ORIGINALLY DEVELOPED FROM THE RESULTS OF THE AASHO ROAD TEST. SPECIFIC AND GENERAL RECOMMENDATIONS ARE PRESENTED AND DISCUSSED.
