摘要：	The performances of 13 proprietary cold-mix patching materials, 4 of which are currently approved under the Virginia Department of Transportation's Special Provision for High Quality Cold Patching Materials, were evaluated. Cold-mix patching materials are regularly submitted to the Materials Division for approval. The purpose of the evaluations was to determine which of the submitted materials were of the same caliber as the approved materials. The addition of materials of equal quality will promote competition in the competitive bid system. Three test sections were placed to evaluate the materials' performance. A standardized evaluation form and performance model were developed to rank the materials. The field performance results were compared with laboratory test results in an effort to develop a laboratory screening test. Design and quality control procedures were identified. These procedures were used to design a material that has performed well.
