THIS SYMPOSIUM ON THICK LIFT CONSTRUCTION IS DIVIDED INTO FOUR SECTIONS. THE FIRST SECTION--STRUCTURAL DESIGN CONSIDERATIONS--ILLUSTRATES EXISTING AND POTENTIAL PAVEMENT DESIGN (THICKNESS SELECTION) PROCEDURES FOR THICK LIFT ASPHALT CONCRETE SECTIONS RESTING DIRECTLY ON PREPARED SUBGRADES. IN ADDITION, A METHOD USING RECENT RESEARCH DEVELOPMENTS INTENDED TO BROADEN THE DESIGN FRAMEWORK FOR SUCH PAVEMENTS AND BASED ON CONCEPTS EMBODIED IN THE SHELL PROCEDURE IS ALSO BRIEFLY ILLUSTRATED. THE SECOND SECTION--MIX DESIGN CONSIDERATIONS--POINTS OUT THAT CONVENTIONAL MIX DESIGN PROCEDURES ARE GENERALLY SUITABLE FOR DESIGNING ASPHALT PAVING MIXTURES FOR THICK LIFT CONSTRUCTION. IT ALSO IS POINTED OUT THAT INFORMATION IS AVAILABLE ON HOW VARIOUS MIX DESIGN VARIABLES AFFECT THE BASIC MATERIAL PROPERTIES OF ASPHALT PAVING MIXTURES SUCH AS ELASTIC, FATIGUE, AND FRACTURE STRENGTH PROPERTIES. SECTION THREE--LABORATORY CONSIDERATIONS--DEALS PRIMARILY WITH THOSE METHODS UTILIZED TO OBTAIN THE MATERIAL PARAMETERS USED IN THE DESIGN PROCEDURES DISCUSSED IN THE FIRST SECTION. SECTION FOUR--CONSTRUCTION METHODS --PRESENTS A CONTEMPORARY VIEW OF CONSTRUCTION METHODS AND PROCEDURES. A DISCUSSION IS INCLUDED WHICH DEALS WITH VARIOUS QUESTIONS ARISING FROM THIS SYMPOSIUM.
