SOME FACTORS AFFECTING THE ESTIMATE OF SOIL STRENGTH AT SALISBURY AIRPORT

PRIOR TO THE LENGTHENING OF THE RUNWAY AND TAXIWAYS AT SALISBURY AIRPORT, THE SOIL WAS SAMPLED AT RANDOM AND ANALYZED STATISTICALLY TO ESTIMATE THE DEGREE OF VARIABILITY IN EACH SOIL HORIZON. TESTS WERE ALSO UNDERTAKEN TO DETERMINE THE REPRODUCIBILITY AND REPEATABILITY OF C.B.R. RESULTS AND TO ESTIMATE THE EFFECT OF LABORATORY ERRORS. THE EXISTING PAVEMENT WAS CONSTRUCTED IN 1952 AND RECORDS OF SOIL MOISTURE ARE GIVEN. THE IMPLICATIONS OF USING THIS INFORMATION TO PREDICT MOISTURE CONDITIONS UNDER THE NEW EXTENSIONS ARE DISCUSSED. THE RESULTS SHOW SOME OF THE ADVANTAGES OF STATISTICAL ANALYSES IN EVALUATING SOIL VARIABILITY. THE MAGNITUDE OF LABORATORY VARIATIONS IN C.B.R. RESULTS IS ALSO SHOWN. WITH REGARD TO THE ULTIMATE SUBGRADE MOISTURE EQUILIBRIUM, IT IS CONCLUDED THAT THE MOISTURE CONDITION VARIES SIGNIFICANTLY FROM SEASON TO SEASON DEPENDING ON THE RAINFALL. THE RANGE OF MOISTURE THAT CAN BE ANTICIPATED UNDER THE NEW EXTENSIONS IS GIVEN. /RRL/
