INTRODUCTION TO THE SYMPOSIUM ON ASPHALT PAVING MIXTURES

THESE PAPERS WERE PREPARED TO MAKE INVESTIGATIONAL DATA, OBTAINED TO DATE, AVAILABLE IN CONDENSED FORM TO HIGHWAY DESIGN AND CONSTRUCTION ENGINEERS. IN PAPER NO. 2, THE PRELIMINARY ANALYSIS MADE TO SELECT TEST APPARATUS IS SUMMARIZED AND IN PAPER NO. 3, THE RESULTS OF THE FIRST LABORATORY STUDY ARE REVIEWED. IN PAPER NO. 4, THE CONSTRUCTION AND TESTING OF A FIELD TEST SECTION, TOGETHER WITH ANALYSIS OF THE DATA, ARE PRESENTED. PAPER NO. 5 PRESENTS THE ADJUSTMENTS THAT WERE MADE IN THE LABORATORY TEST PROCEDURES TO INSURE THAT SPECIMENS ON WHICH DESIGNS WOULD BE BASED WOULD CLOSELY APPROACH FIELD CONDITIONS. THE FINAL DETAILED TEST PROCEDURES FOR THE METHOD ARE PRESENTED IN PAPER NO. 6. PAPER NO. 7 SHOWS HOW THE METHOD IS USED IN THE ACTUAL DESIGN AND CONSTRUCTION OF A PAVEMENT AND THE CLOSING PAPER DISCUSSES THE DESIGNS AS RELATED TO OTHER FEATURES OF A FLEXIBLE PAVEMENT.
