DESIGN CONSTRUCTION, AND INITIAL EVALUATION OF EXPERIMENTAL TEST SECTIONS OF ASPHALT CONTAINING SYNTHETIC RUBBER

THE 16 TEST SECTIONS OF ASPHALT CONTAINING RUBBER WERE CONSTRUCTED AS PART OF A PRIMARY HIGHWAY PROJECT IN SOUTHEASTERN UTAH. THE EXPERIMENT CONSISTS OF 5 FACTORS AT 2 LEVELS, EACH INCORPORATED IN A ONE-HALF REPLICATE OF A 2 TO THE FIFTH POWER FRACTIONAL FACTORIAL EXPERIMENT. THE DESIGN PROVIDES THE BASIS FOR DETERMINING THE EFFECT OF EACH OF 5 FACTORS AND EACH OF 10 TWO-WAY INTERACTIONS ON PAVEMENT CONSTRUCTION, PERFORMANCE, AND DESIGN. THE EFFECT OF EACH VARIABLE WAS DETERMINED FOR THE CONSTRUCTION PROCESS, AND AN INITIAL EVALUATION WAS MADE. A DESCRIPTION OF THE CONSTRUCTION PROCESS, INCLUDING THE RUBBERIZING PROCESS, IS GIVEN. EVALUATION IS CONTINUING THROUGH MANY OBSERVATIONS AND PHYSICAL TESTS ON THE PAVEMENTS AND PAVING MATERIALS. FAILURE RATE OF PAVEMENTS WILL BE ACCELERATED BY THE REDUCTION OF HALF THE DESIGN THICKNESS. THE DESIGN PROVIDES A SOUND METHOD OF ANALYSIS AND OFFERS A DEFINITE BASIS TO DETERMINE WHICH FACTORS AND INTERACTIONS ARE SIGNIFICANTLY AFFECTING PAVEMENT PERFORMANCE AND DESIGN. /AUTHOR/
