Abstract:

This research project was undertaken to examine the practicality and adequacy of the FDOT specifications regarding compaction methods for pipe trench backfills under high water table. Given the difficulty to determine density and to attain desired degree of compaction under high water table areas, typical in South Florida, it was alleged that the specification is difficult to follow. The main objective of this research project was to evaluate the variations in soil conditions, as determined by the Standard Penetration Test (SPT) N-values, as a result of varying methods of compaction. In this summary report, we highlight the major findings of the field tests conducted in simulated trenches.
