NONDESTRUCTIVE MEASUREMENT OF SUBGRADE MOISTURE VARIATIONS

A SIX-YEAR STUDY WAS CONDUCTED TO MEASURE SUBGRADE MOISTURE VARIATIONS UNDER HIGHWAY SUBGRADES TO: (1) DEVELOP AN EFFECTIVE PROCEDURE FOR MEASURING SUBGRADE MOISTURE VARIATIONS, (2) DEVELOP PROCEDURES FOR MAKING THESE MEASUREMENTS THROUGHOUT OKLAHOMA, (3) RELATE MEASURED MOISTURED CHANGES TO SOIL, CLIMATE, AND PAVEMENT CONDITIONS, AND (4) SUGGEST REVISED DESIGN PROCEDURES TO IMPROVE PAVEMENT PERFORMANCE. TWO SETS OF NUCLEAR DEPTH MOISTURE AND DENSITY EQUIPMENT WERE USED TO COLLECT FIELD DATA. PAVEMENT CONDITION RATINGS WERE MADE PERIODICALLY AT EACH SITE, AND ATTEMPTS ARE BEING MADE TO EVALUATE FIELD DATA COLLECTED. IT IS CONCLUDED THAT THE PROJECT DEVELOPED EFFICIENT PROCEDURES FOR IN-PLACE NON-DESTRUCTIVE MEASUREMENT OF SUBGRADE MOISTURE VARIATIONS, USING NUCLEAR DEPTH MOISTURE AND DENSITY EQUIPMENT.
