FEASIBILITY OF LIGHTWEIGHT CELLULAR CONCRETE FOR VEHICLE CRASH CUSHIONS
THREE VEHICLE CRASH TESTS OF LIGHTWEIGHT CELLULAR CONCRETE CRASH CUSHIONS ARE REPORTED, ALONG WITH PROPOSED PROCEDURES FOR CAST-IN-PLACE AND PRECAST CONSTRUCTION OF THESE DEVICES. THIS CRASH CUSHION, COMPOSED OF VERMICULITE CONCRETE, LIGHTWEIGHT WELDED WIRE FABRIC, AND CYLINDRICAL CARDBOARD FORMS, IS DESIGNED TO PROTECT MOTORISTS FROM COLLISIONS WITH RIGID OBSTACLES LOCATED ALONG THE ROADWAY. THE CRASH CUSHION HAS PROVED CRASH-WORTHY UNDER HEAD-ON TEST CONDITIONS. /AUTHOR/
