PAINTING OF HIGHWAY STEEL
EXPERIENCES OF THE AUTHOR IN 18 YEARS OF 'TROUBLE- SHOOTING' PREMATURE PAINT FAILURES ON HIGHWAY STEEL ARE PRESENTED. CAUSES OF SUCH FAILURE, AND RECOMMENDATIONS FOR THEIR PREVENTION ARE FULLY DISCUSSED. BY FAR THE GREATEST FACTORS CAUSING PREMATURE FAILURE OF HIGHWAY PAINTING JOBS ARE SUBSTANDARD SURFACE PREPARATION AND DEFICIENT PAINT THICKNESSES. IN GENERAL, PRESENT SPECIFICATIONS AND MATERIALS ARE ADEQUATE, BUT INSPECTION SHOULD BE IMPROVED. GREATER BENEFITS WILL ACCRUE FROM GREATER ATTENTION TO INSPECTION PROCEDURES THAN FROM CURRENT ACTIVITIES OF PAINT TESTING.MATERIAL TESTING AND PAINTING ADVISORY SERVICES. COULD BE MOST ECONOMICALLY AND EFFECTIVELY PERFORMED BY A CENTRAL AGENCY, SUPPORTED BY, AND SERVING ALL STATES AND AUTHORITIES. ZINC-FORTIFIED PROTECTIVE SYSTEMS HAVE AN ADVANTAGE OVER CURRENTLY USED BARRIER PAINT SYSTEMS. TRADITIONAL PAINTING PROCEDURES SHOULD BE DISCONTINUED, AND PAINTING CONDUCTED AT CENTRALIZED LOCATIONS PRIOR TO ERECTION. /AUTHOR/
