DESIGN AND CONSTRUCTION OF TRANSPORTATION FACILITIES

A SYSTEMS APPROACH THAT WILL ISOLATE RESEARCH NEEDS AND ESTABLISH PRIORITIES IS PROPOSED. THE OVERLAY DESIGN FORMULA CONSIDERS FIVE ELEMENTS THAT ARE NECESSARY FOR A MORE RATIONAL PAVEMENT DESIGN METHOD: (1) BEHAVIOR MODEL; (2) MATERIAL CHARACTERISTICS APPROPRIATE TO THE BEHAVIOR MODEL; (3) DAMAGE CONCEPT; (4) FAILURE CRITERIA; AND (5) DESIGN CRITERIA. OUTPUT FROM THIS PORTION OF THE SYSTEM IS MODIFIABLE ON THE BASIS OF FEEDBACK PROCESSES. RESEARCH NEEDS ARE LISTED IN THREE AREAS: (1) NEEDS RELATED TO SYSTEM INPUT DATA; (2) NEEDS RELATED TO OVERLAY DESIGN FORMULAS; AND (3) NEEDS RELATED TO MODIFICATIONS TO THE DESIGN SYSTEMS FOR NEW CONSTRUCTION OR THE BASE DESIGN SYSTEM FOR COMPOSITE PAVEMENTS.
