ASPHALT PAVING TECHNOLOGY-SOME CURRENT DEVELOPMENTS AND TRENDS

A BRIEF SUMMARY IS PRESENTED OF RESEARCH AND DEVELOPMENT TRENDS IN THE DESIGN, CONSTRUCTION AND PERFORMANCE OF ASPHALT PAVEMENTS. IMPROVEMENT EFFORTS HAVE INCLUDED ACTIVITIES RELATED TO: (1) DEVELOPMENT OF IMPROVED SPECIFICATIONS FOR ASPHALT, (2) MEASUREMENT OF THE RESPONSE CHARACTERISTICS OF ASPHALTS AND ASPHALT PAVING MIXTURES IN MORE FUNDAMENTAL TERMS, (3) ANALYSIS OF SYSTEMS REPRESENTATIVE OF ASPHALT PAVEMENT STRUCTURES WITH SOME APPLICATIONS TO DESIGN, (4) CONSTRUCTION OPERATIONS INCLUDING THICK-LIFT ASPHALT CONCRETE CONSTRUCTION, USE OF PNEUMATIC-TIRED ROLLERS, AND INCREASED MIXTURE PRODUCTION CAPABILITIES, AND (5) CONSTRUCTION CONTROL INCLUDING STATISTICAL SPECIFICATIONS AND IMPROVED CONTROL OF THE COMPACTION OPERATION THROUGH ESTABLISHMENT OF COMPACTION EFFORT BY MEANS OF SMALL TEST SECTIONS, PAVEMENT PERMEABILITY MEASUREMENTS, OR NUCLEAR MEASUREMENTS. AN EXAMPLE IS PRESENTED TO DESCRIBE THE RESULTS OF SOME OF THESE STUDIES THAT HAVE BEEN UTILIZED TO DEVELOP A PAVEMENT DESIGN FOR A CITY-COUNTY HIGHWAY IN CALIFORNIA. TRENDS ILLUSTRATED IN THE EXAMPLE ARE THESE OF FIXED SECTIONS OF ASPHALT CONCRETE, PARTICULARLY FOR HEAVY DUTY HIGHWAYS, THE USE OF THEORY TO ASSIST IN DESIGN, IMPROVED CHARACTERIZATION OF MATERIALS TO UTILIZE THEORY AND COMPACTION PROCEDURES TO ACCOMPANY THICK-LIFT DESIGNS. ADDITIONAL TOOLS ARE PRESENTED AS SUPPLEMENTING EXISTING PROCEDURES TO EXTEND THE SCOPE OF ASPHALT PAVING TECHNOLOGY.
