CASE STUDIES OF VARIATIONS IN SUBGRADE MOISTURE AND TEMPERATURE UNDER ROAD PAVEMENTS IN VIRGINIA

Changes in moisture under uncovered ground and in the subgrades of pavements were evaluated. The pavements ranged from new to about 10 years old. Moisture content was determined by a nuclear probe to determine moisture depth. The findings were as follows: (a) the higher the compaction and dry density of the subgrade soil were, the lower the moisture content would be; (b) subgrade moisture content increased sharply from the beginning to the end of construction; (c) for 1 or 2 years from the date of the subgrade construction, moisture content increased because of precipitation and after this time the rate of increase in moisture decreased; and (d) after about 10 years, there was little increase in the subgrade moisture content.
