Abstract:

An investigation of a family of thermoplastic asphalt compositions for allweather permanent street patching applications was conducted by Public Technology, Inc., and Products Research and Chemical Corporation under contract to the National Aeronautics and Space Administration. Ten ethylene-vinyl acetate copolymers were laboratory-tested in different ratio combinations with various penetration-grade asphalts. The physical properties of these compositions were related to the functional requirements for a street patching material established by Public Technology's User Requirements Committee composed of street superintendents, public works directors, city administrators, and others. Two formulations were selected for preliminary field-testing at 3 sites: Burbank, California; South Lake Tahoe, California; and Anchorage, Alaska. The field-test results (after 2 months) indicate considerable promise for the material for emergency patching. A cost-effectiveness analysis indicates that if the new material has a road life twice that of current emergency patching materials then it is as cost-effective as current materials. This is calculated on the basis of total costs (materials, equipment, and labor) averaged from data for 12 cities.
