SUBGRADE MOISTURE VARIATIONS, EVALUATION OF COLLECTED DATA 1966-1967

DATA COLLECTED AT FIELD TEST SITES 1-30 DURING THE PERIOD JUNE, 1966 - AUGUST, 1967 ARE EVALUATED, RELATING MEASURED SUBGRADE MOISTURE CHANGES TO SOIL, CLIMATE, AND PAVEMENT CONDITIONS. RELEVANT DATA WERE CODED ON IBM CARDS AND SORTED MECHANICALLY TO OBTAIN INITIAL CORRELATIONS. ENGINEERING JUDGMENT WAS THEN APPLIED TO DEVELOP MORE DETAILED RELATIONSHIPS. CAUSE, EXTENT, AND EFFECT OF SUBGRADE MOISTURE VARIATIONS ARE DISCUSSED, AS ARE GENERAL TRENDS OBTAINED FROM THE COLLECTED DATA. RESULTS OBTAINED FROM PREVIOUS SUBGRADE MOISTURES STUDIES BY OTHER AGENCIES ARE ALSO PRESENTED. RESULTS OF THE EVALUATION SUBSTANTIATED SOME THEORIES OF MOISTURE MIGRATION AND SHOWED INTERESTING QUANTITATIVE TRENDS. RESEARCH PROCEDURES ARE VERIFIED AND GUIDELINES ARE ESTABLISHED FOR FUTURE RESEARCH ACTIVITIES. /AUTHOR/
