FLEXIBLE DESIGN GUIDE FOR HIGHWAYS

THE PRINCIPAL FACTORS TO BE CONSIDERED IN SELECTING BOTH TOTAL THICKNESS AND OPTIMUM COMPONENT APPROPRIATE TO FLEXIBLE PAVEMENTS FOR ANY HIGHWAY DESIGN SITUATION ARE DISCUSSED. THE SYSTEM DESCRIBED IS MOST APPLICABLE WHEREVER CRUSHED STONE WITH THE REQUIRED INHERENT QUALITY, SUBJECTED TO CAREFUL PROCESS CONTROL, IS AVAILABLE FOR INCORPORATION INTO THE VARIOUS COMPONENTS. TWO BASIC FACTORS MUST BE CONSIDERED IN PAVEMENT THICKNESS DESIGN. THESE ARE SOIL SUPPORT AND TRAFFIC INTENSITY. TO EVALUATE SOIL SUPPORT, A CBR TEST PROCEDURE IS CAREFULLY DESCRIBED AND REFERENCED. METHODS FOR DEFINING TRAFFIC INTENSITY IN TERMS OF DESIGN INDEX CATEGORIES ARE ALSO SUGGESTED. TO ASSIST THE DESIGNER WHO HAS FAMILIARIZED HIMSELF WITH THESE DETAILS, THE BASIC DESIGN THICKNESS CHART IS REPRODUCED IN ENLARGED FORM FOR EASIER READING. A METHOD OF ADJUSTING THE DESIGN THICKNESS FOR SEVERE CLIMATE CONDITIONS, WHERE NECESSARY, IS ALSO DESCRIBED. /AUTHOR/
