DYNAMIC TESTS OF AN ENERGY-ABSORBING BARRIER EMPLOYING SAND-FILLED PLASTIC BARRELS

THE RESULTS OF THREE FULL-SCALE TESTS OF VEHICLES IMPACTING ENERGY-ABSORBING BARRIERS EMPLOYING SAND-FILLED FRANGIBLE PLASTIC BARRELS ARE REPORTED. THE BARRIERS WERE DESIGNED FOR PLACEMENT IN FRONT OF FIXED OBJECTS LOCATED IN FREEWAY GORES. THEY WERE COMPOSED OF AN ARRAY OF 15 TO 17 BARRELS 36 IN. IN DIAMETER BY 30 AND 36 IN. HIGH. THE BARRIERS WERE 21 AND 25 FT LONG AND TAPERED FROM A 9-FT WIDTH AT THE REAR TO A 3-FT WIDTH AT THE NOSE. THE BARRELS WERE NOT ATTACHED TO THE GROUND. SEDANS WEIGHING APPROXIMATELY 4,700 LB IMPACTED THE NOSE OF THE BARRIER HEAD ON AT A SPEED OF APPROXIMATELY 60 MPH AND AT A 15-DEG ANGLE. A SMALL SEDAN WEIGHING ABOUT 1,900 LB ALSO IMPACTED THE NOSE OF THE BARRIER HEAD ON AT 59 MPH. THE BARRIER WAS JUDGED ACCEPTABLE IN THE AREAS OF COST, EASE OF CONSTRUCTION AND MAINTENANCE, AESTHETICS, SIMPLICITY, AND VERSATILITY AND IS RECOMMENDED FOR USE IN OPERATIONAL TRIAL INSTALLATIONS. /AUTHOR/
