BITUMINOUS BASE COATING USED ON HIGHWAY GUARD RAILS INCLUDES COLORED CERAMIC GRANULES

THIS ARTICLE DISCUSSES THE USE OF A BITUMINOUS BASE COATING WITH COLORED CERAMIC GRANULES FOR THE PROTECTION OF GUARD RAILS ALONG HIGHWAYS. ON THE INDIANA TOLL ROAD, THE BITUMINOUS SYSTEM PROVED TO BE PARTICULARLY RESISTANT TO THE EFFECTS OF SALT. IT IS HOPED THAT THIS BITUMINOUS BASE COATING WILL GIVE PROTECTION FOR FIFTEEN YEARS. ALTHOUGH THE INITIAL EXPENSE IS HIGHER THAN PAINT, THE LONGER LIFE EXPECTANCY OFFSETS THIS. APPLICATION IS A TWO-STEP METHOD' AFTER THOROUGH PREPARATION, THE BITUMINOUS BASE COATING IS SPRAYED DIRECTLY ON THE RAILS. BEFORE THIS IS COMPLETELY DRY, THE SELF-CLEANING CERAMIC GRANULES ARE SANDBLASTED ON TO IT. STANDARD EQUIPMENT CAN BE USED. THE COATING SYSTEM WAS FIRST USED LAST YEAR ALONG THE INDIANA TOLL ROAD, THE EAST HUDSON PARKWAY AUTHORITY ON THE SAW MILL RIVER PARKWAY IN NEW YORK'S WESTCHESTER COUNTY, THE PENNSYLVANIA TURNPIKE NEAR HARRISBURG, THE CONNECTICUT INTERSTATE HIGHWAY NEAR HARTFORD, AND THE OHIO TURNPIKE.
