Hot Melt Traffic Marking Materials

摘要

Extraordinary durability and quick-setting characteristics have firmly established hot thermoplastic as a preferred material for urban ccross-walk delineation. However, its highway use for center striping has been hampered by high application costs and somewhat variable performance experience. 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. The effectiveness of bonding agents for attaining durable adhesion to portland cement concrete was also demonstrated. Concurrent laboratory researches on the field-tested materials and numerous variations provided indications of the interrelationships of composition, physical properties, application, and performance.
