BACKFILLING TRENCH EXCAVATIONS

ON THE BASIS OF PAST STUDIES IT WAS DECIDED THAT ADDITIONAL STUDIES SHOULD BE MADE TO DETERMINE WHERE THE SETTLEMENT OR CONSOLIDATION OCCURS IN A TRENCH AND ALSO TO DETERMINE THE EFFECT OF RELATIVE DENSITY ON SETTLEMENT. THE NUMBER OF DUMMY TRENCHES WAS STUDIED INCLUDING INSTALLING MEASUREMENT SYSTEMS, AND MAKING THE NECESSARY OBSERVATIONS AND CALCULATIONS. A SECTION OF BITUMINOUS SURFACED COUNTY ROAD WITH A PLASTIC SUBGRADE WAS SELECTED AS THE SITE FOR THE CONSTRUCTION OF 17 DUMMY TRENCHES. /AUTHOR/
