ACCELERATED TRAFFIC TEST AT LANGLEY FIELD, VIRGINIA

AN ACCELERATED TRAFFIC TEST WAS CONDUCTED ON A SPECIALLY CONSTRUCTED FLEXIBLE PAVEMENT TEST TRACK TO STUDY THE BEHAVIOR OF BASE AND PAVEMENTS OF VARIOUS THICKNESSES PLACED ON A LOW PLASTIC SUBGRADE WHEN SUBJECTED TO WHEEL LOADS OF 20,000 AND 50,000 LB, AND TO OBTAIN DATA NECESSARY FOR THE DEVELOPMENT OF DESIGN CURVES FOR THE CALIFORNIA METHOD OF DESIGN OF FLEXIBLE PAVEMENT. THE HYDROSTATIC EXCESS PRESSURE IN THE SUBGRADE PORE WATER (QUICK CONDITION) GREATLY AFFECTED THE BEHAVIOR OF THE TEST SECTION, CAUSING SPRINGING OF THE PAVEMENT AT 20,000 LBS. AND TOTAL FAILURE AT 50,000 LBS. THESE RESULTS EMPHASIZE THE NEED FOR SUBGRADE COMPACTION OR AMPLE THICKNESS OF BASE OVER SATURATED, FAIRLY LOW DENSITY, FINE SANDS AND SILTS THAT MAY BECOME QUICK DURING AIRPLANE TRAFFIC. /AUTHOR/
