MATERIAL WAS PREPARED IN A CONTINUOUS BATCH PLANT USING CRUSHED LIMESTONE WITH CRUSHED SAND, ASPHALTIC CONTENT 5.1 PERCENT /DESIGN/. RANDOM SAMPLING WAS PERFORMED TO OBTAIN DATA ON TEMPERATURE, THICKNESS AND DENSITY IN THE FIELD. LABORATORY TESTS ON STABILITY, GRADATION, ASPHALT CONTENT AND VOIDS WERE PERFORMED. DATA SHEET COPIES AS WELL AS THE COMPILTATION OF THE STATISTICAL PARAMETERS FOR MATERIAL CHARACTERISTICS ARE INCLUDED. THE STATISTICAL PARAMETERS INCLUDE STANDARD DEVIATION, VARIANCE DUE TO MATERIAL, SAMPLING AND TESTING, AND OVERALL COEFFICIENT OF VARIATION.
