  • Patent number: 5366320
    Abstract: An improved screed for leveling abrasive paving material on a road surface. The improved screed is attachable to a typical road paving machine using standard mounting assembly and attachment components. The improved screed is highly abrasion-resistant and loses much less heat during shutdown periods than steel screeds because it is formed of a composite that includes a chromium-carbide alloy. The composite is formed of a relatively soft metal that is essentially completely fused to the chromium-carbide alloy. The highly abrasion-resistant alloy, which has a Brinell hardness in the range 550 to 600 and a low coefficient of friction, comes in direct contact with the abrasive paving material and its low thermal conductivity permits it to retain heat during shutdown.
