DURABLE PAVEMENT-MARKING MATERIALS

Work done by the Minnesota Department of Transportation during the past 10 years to develop and evaluate a durable yet economical road-striping material is described. The development of equipment capable of applying a two-component epoxy resin is discussed. Epoxy, polyester, and thermoplastic resins and their cost-effectiveness are evaluated. Field evaluation of the various materials consisted of visual observations, photographs, macrophotographs, and measurements of retroreflectivity. The available data suggest that epoxy can be placed on a high-volume bituminous or portland cement concrete roadway, at a thickness of 10 mils, and provide adequate delineation for 12 months or longer while remaining as economical as paint. The polyester material did not adhere well to portland cement concrete and the aggregate in the bituminous pavement. Thermoplastic was found to be generally unacceptable because it is to susceptible to removal by traffic and snowplows when placed at the manufacturer's recommended minimum thickness of 30 mils and it does not bond adequately to portland cement concrete.
