HOT MELT TRAFFIC MARKING MATERIALS

LABORATORY AND HIGHWAY TRANSVERSE-STRIPE TESTING HAS BEEN PERFORMED ON PROPRIETARY, SPECIFICATION-TYPE, AND EXPERIMENTAL COMPOSITIONS OF HOT MELTS. THE RESULTS OF TWO YEARS OF TRANSVERSE-STRIPE TESTS UNDER VERY HEAVY TRAFFIC CONDITIONS HAVE CLEARLY CONFIRMED EARLIER FINDINGS: HOT MELT SERVICE LIFE IS GREATLY SUPERIOR TO TRAFFIC PAINT. THE EFFECTIVENESS OF BONDING AGENTS FOR ATTAINING ADHESION TO PORTLAND CEMENT CONCRETE WAS ALSO DEMONSTRATED, CONCLUSIVELY. CONCURRENT LABORATORY RESEARCHES ON THE FIELD- TESTED MATERIALS AND NUMEROUS VARIATIONS PROVIDED INDICATIONS OF THE INTERRELATIONSHIPS OF COMPOSITION, PHYSICAL PROPERTIES, APPLICATION, AND PERFORMANCE. HOT MELT TRAFFIC STRIPE MATERIAL SPECIFICATIONS WERE DRAFTED BASED ON PHYSICAL PROPERTY AND LABORATORY PERFORMANCE TEST CRITERIA. THESE SPECIFICATIONS ARE BELIEVED TO DEFINE THE PRESENT STATE OF THE ART AND TO PROVIDE SUPPLIERS WITH YARDSTICKS FOR FURTHER DEVELOPMENTS. HIGHWAY USE OF THERMOPLASTIC LINES MIGHT REMAIN HIGHLY SELECTIVE AS LONG AS IT REPRESENTS MERELY A MORE DURABLE REPLACEMENT FOR TRAFFIC PAINTS. EXPLORATORY EXPERIMENTS HAVE SHOWN THE THERMOPLASTIC LINES CAN BE TEXTURED SO AS TO IMPACT EFFECTIVE DELINEATION UNDER NIGHTTIME CONDITIONS. A COST-EFFECTIVENESS ANALYSIS OF HOT THERMOPLASTIC AS COMPARED WITH TRAFFIC PAINTS INDICATED, AT BEST, ONLY MARGINAL EFFECTIVENESS FOR THE HOT THERMOPLASTIC. FOR MOST HIGHWAY USAGE, DEVELOPMENT OF THE WET NIGHT VISIBILITY POTENTIAL WOULD BE NECESSARY TO JUSTIFY ADOPTION OF HOT THERMOPLASTIC STRIPING. /AUTHOR/
