AN EXPERIMENTAL GLARE SCREEN INSTALLATION ON U.S. 101 IV-MRN-1-C BETWEEN TAMALPAIS ROAD AND CORTE MADERA CREEK

THE REPORT SUMMARIZES THE EFFECTIVENESS OF SIX DIFFERENT TYPES OF SCREEN MATERIAL EXPOSED UNDER EXPERIMENTAL FIELD CONDITIONS. THE TYPES INCLUDED CHLOROSULFONATED POLYETHYLENE COATED NYLON WEBBING WOVEN INTO TWO INCH GALVANIZED STEEL CHAIN LINK MESH, POLYPROPYLENE WEBBING WOVEN INTO CHAIN LINK MESH, PREPAINTED ALUMINUM SLATS, AMORPHOUS PHOSPHATE-CHROMATE COLOR TREATED ALUMINUM SLATS, EXPANDED GALVANIZED STEEL AND EXPANDED PREPAINTED ALUMINUM. THE OBJECTIVES WERE TO TEST THE EFFECTIVENESS OF EACH TYPE AS A HEADLIGHT GLARE SCREEN AND TO TEST DURABILITY AND RELATIVE MAINTENANCE COSTS AND EASE OF REPLACEMENT. THE RESULTS OF OBSERVATIONS AND TESTS WERE THE BASIS FOR RECOMMENDING PREPAINTED EXPANDED ALUMINUM MESH FOR GLARE SCREENS ON CABLE TYPE MEDIAN BARRIERS. /BPR/
