COMPACTION OF TRENCHES - WIDENING, HARD SHOULDERS, DRAINAGE TRENCHES

LE COMPACTAGE DES TRANCHEES - ELARGISSEMENTS, ACCOTEMENTS, EPAULEMENTS, TRANCHEES D'ASSAINISSEMENT

THE BACKFILL AND COMPACTION OF TRENCHES (WIDENING - HARD SHOULDERS - DRAINAGE) GIVE RISE TO NUMEROUS TECHNICAL PROBLEMS IN THE REPAIR OF ROADS. THE MAIN DIFFICULTIES COME FROM THE ADAPTATION OF COMPACTION MACHINES TO THE GEOMETRY OF THE TRENCHES AND TO THE BACKFILL MATERIAL. THE AUTHORS RECALL THE EFFECTS OF INSUFFICIENT COMPACTION ON THE BEHAVIOUR OF PAVEMENT STRUCTURES; AN INVENTORY IS PRESENTED OF THE AVAILABLE TYPES OF EQUIPMENT AND THEIR PERFORMANCE (VIBRATING ROLLERS, VIBRATING PLATES, TAMPERS). A STUDY OF THE MAIN CASES ENCOUNTERED SHOWS THAT IT IS ADVISABLE TO ADAPT COMPACTION EQUIPMENT (VIBRATING OR STATIC) ACCORDING TO THE GEOMETRY OF THE TRENCH AND THE PRESENCE OF PIPES. GUIDELINES ARE PROPOSED FOR THE DESIGN AND CONSTRUCTION STAGES WITH EMPHASIS ON A SUITABLE QUALITY/COST RELATION.
