EXPLOSIVE EXCAVATION RESEARCH
RESEARCH TO DEVELOP EXPLOSIVE EXCAVATION AS AN ACCEPTED COST-COMPETITIVE CONSTRUCTION TECHNIQUE IS BEING CONDUCTED BY THE U. S. ARMY ENGINEER WATERWAYS EXPERIMENT STATION EXPLOSIVE EXCAVATION RESEARCH OFFICE. TWO EXPLOSIVES, AMMONIUM NITRATE-FUEL OIL (ANFO) AND THE ALUMINIZED AMMONIUM NITRATE SLURRIES, APPEAR TO OFFER THE BEST CHARACTERISTICS AND COST ADVANTAGES. PROJECTS PRESENTLY IN PROGRESS OR UNDER STUDY INCLUDE A HIGHWAY CUT, SPILLWAY APPLICATIONS, HARBOR EXCAVATION, AND SEVERAL MILITARY APPLICATIONS. LARGE REDUCTIONS IN EMPLACEMENT AND EXPLOSIVES COSTS HAVE BEEN EXPERIENCED IN THE PAST TWO YEARS IN THE PROCESS OF DEVELOPING EXPLOSIVE EXCATION, AND FURTHER SIGNIFICANT REDUCTIONS APPEAR FEASIBLE. THESE REDUCTIONS, WHEN COMBINED WITH MORE EFFICIENT DESIGNS AND EXECUTION TECHNIQUES, SHOULD CONTINUE THE DOWNWARD COST TREND OF EXPLOSIVE EXCAVATION. /BJ/
