Samenvatting
This paper describes the design and testing of an improved bridge parapet which was subsequently incorporated in two bridge structures at the general Motors Proving Ground. These parapets are designed to provide maximum safe to the occupants of vehicles which might strike them. Testing involved running full-scale remotely controlled vehicles into test sections constructed especially for this purpose. These vehicles included passenger cars of various sizes and a loaded 2-112-ton truck. Performance of the final design is satisfactory in all respects and costs are not excessive.
