SMALL APERTURE TESTING FOR AIRFIELD PAVEMENT EVALUATION

A SMALL APERTURE TECHNIQUE WAS DEVELOPED TO OBTAIN CBR STRENGTH VALUES AND SAMPLES USED TO DETERMINE MOISTURE, DENSITY, AND CLASSIFICATION OF AIRFIELD PAVEMENT COMPONENTS THROUGH A 6-IN.-DIAM. CORE HOLE. EQUIPMENT AND TEST PROCEDURES ARE DISCUSSED. DATA OBTAINED BY THE SMALL APERTURE METHOD ARE SHOWN TO AGREE WELL WITH THOSE OBTAINED BY CONVENTIONAL TEST PROCEDURES. A NUCLEAR DENSITY DEVICE DEVELOPED ESPECIALLY FOR THIS STUDY IS DISCUSSED, AND DATA ARE PRESENTED THAT SHOW THE ACCURACY OF THE DEVICE. THE SMALL APERTURE TESTS WERE NOT FOUND TO HAVE A TIME ADVANTAGE, BUT MANPOWER REQUIREMENTS WERE CUT IN HALF. THE TESTS CAN BE PERFORMED BETWEEN TRAFFIC OPERATIONS, AND MOST AIRCRAFT CAN OPERATE OVER THE 6-IN.-DIAM CORE HOLE.
