The study reported was initiated to evaluate available new patching materials for both flexible and rigid pavements. An infrared heater also was used for cold-weather flexible-pavement patching. The Department's cold mix and a proprietary mix were used to fill potholes in flexible pavements during two winters; the more expensive proprietary mix proved to be a durable repair material for winter patching. Summer patching was not investigated on flexible pavements because the Department's standard top-course mix is used and presents no problems. Fourteen cement-base and two asphalt-base materials were used to repair rigid pavement. Six cement- and one asphalt-base materials were used in winter, with only the latter providing good service. The other asphalt and ten cement-base materials were used for summer patching. One asphalt and five cement-base materials provided good enough service to warrant routine use; the others may be used but the reported shortcomings should be considered. A brief comparison of laboratory test results and field performance showed that the former can be used for screening purposed to eliminate unsatisfactory materials, but cannot be used as acceptance criteria.
