CRASH TESTS OF AN ARTICULATED ENERGY-ABSORBING GORE BARRIER EMPLOYING LIGHTWEIGHT CONCRETE CARTRIDGES
THE CONCEPT OF VERMICULITE CONCRETE ENERGY ABSORPTION HAS BEEN FURTHER TESTED BY INCORPORATING CARTRIDGES INTO THE HI-DRO CELL SANDWICH UNIT DESIGNED FOR WATER-CELL USE. REPEATED TESTS WERE PERFORMED WITH GRADUALLY INCREASED USE OF THE CARTRIDGES IN PLACE OF WATER CELLS. TESTS UP TO 55 MPH WITH MEDIUM-WEIGHT AUTOMOBILES INDICATE IMPROVED RESPONSE, ESPECIALLY WITH REGARD TO THE APPROACH TO SQUARE- WAVE DECELERATION PULSE. HARNESS-RESTRAINED DRIVERS REPORTED NO DISCOMFORT IN THREE SEPARATE IMPACTS AT SPEEDS ABOVE 50 MPH. /AUTHOR/
