THE CONSTRUCTION OF ROAD EMBANKMENTS THROUGH PEAT

THE METHODS OF CONSTRUCTION ARE DISCUSSED THAT WERE ADOPTED FOR THE REPLACEMENT OF PEAT WITH HARD-FILLING ON AN 11 MILE SECTION OF THE BELFAST-DUNGANNON MOTORWAY. ON THIS SECTION OVER 3 MILLION CUBIC YARDS OF PEAT, IN DEPTH UP TO 36 FEET, WERE ENCOUNTERED. THE PEAT WAS EXCAVATED BY DRAG- LINES BUT ON A FEW SHORT SECTIONS THE DISPLACEMENT METHOD OF BOG-BLASTING WAS USED. BOTH METHODS ARE DESCRIBED. THE EMBANKMENTS WERE FORMED WITH IMPORTED BROKEN ROCK-FILLING BUT ON ONE CONTRACT NATIVE CLAY FILL WAS USED IN SOME EMBANKMENTS. SOME DATA ARE GIVEN ON THE COMPACTION ACHIEVED IN CLAY EMBANKMENTS AND THE TOTAL SETTLEMENTS WHICH OCCURRED IN A PERIOD AFTER CONSTRUCTION IN BOTH CLAY AND ROCK-FILL EMBANKMENTS. /RRL/A/
