COMPACTION REQUIREMENTS FOR FLEXIBLE PAVEMENTS

THE RESULTS ARE PRESENTED OF AN ANALYTICAL STUDY MADE TO DEVELOP CRITERIA FOR DETERMINING THE DEGREE OF COMPACTION REQUIRED AT DIFFERENT DEPTHS IN SOILS BENEATH FLEXIBLE PAVEMENTS TO PREVENT CONSOLIDATION OF THE SOIL UNDER WHEEL LOADS AND CONSEQUENT DEFORMATION OF THE PAVEMENT. DATA OBTAINED FROM OBSERVATIONS OF AIRFIELD PAVEMENTS IN ACTUAL SERVICE AND FROM REPORTS OF ACCELERATED TRAFFIC TESTS ON CAREFULLY CONTROLLED TEST SECTIONS WERE TABULATED, AND FROM THESE TABULATIONS CORRELATIONS WERE DEVELOPED BETWEEN THE COMPACTION EFFORT APPLIED TO FLEXIBLE PAVEMENTS BY AIRCRAFT TRAFFIC AND THE DENSITIES RESULTING FROM THIS COMPACTION EFFORT AT VARIOUS DEPTHS. THE ESTABLISHED CBR RELATIONS WERE USED TO INTEGRATE THE EFFECTS OF WHEEL LOAD, TIRE PRESSURE, ASSEMBLY CONFIGURATION, AND DEPTH BELOW PAVEMENT SURFACE INTO A COMPACTION INDEX, C FOR PURPOSES OF THIS STUDY. CORRELATIONS BETWEEN C AND THE DENSITIES REQUIRED TO PREVENT FURTHER COMPACTION ARE PRESENTED. /AUTHOR/
