ROCKFILL

THIS PAPER REVIEWS THE DEVELOPMENT OF COMPACTED ROCKFILL AS A CONSTRUCTION MATERIAL FOR EMBANKMENTS, ILLUSTRATES POST-CONSTRUCTION SETTLEMENTS OF ROCKFILL EMBANKMENTS, AND DISCUSSES THE VALUE OF ROCKFILL AS A CONSTRUCTION MATERIAL FOR ROAD EMBANKMENTS. THE ERA OF FREEWAY CONSTRUCTION HAS BROUGHT A REQUIREMENT FOR EMBANKMENT HEIGHTS NOT PREVIOUSLY USED FOR ROAD CONSTRUCTION. ROCKFILL HAS MARKED ADVANTAGES OVER EARTHFILL FOR HIGH EMBANKMENTS BECAUSE, BEING SUBSTANTIALLY WITHOUT CONSTRUCTIONAL PORE PRESURES, IT CAN SAFELY BE RAISED AT A FAST RATE AND BECAUSE STEEPER SIDE SLOPES CAN BE USED AS COMPARED WITH EARTHFILL, SO THAT THE EMBANKMENT REQUIRES A SMALLER VOLUME OF FILL. /AUTHOR/
