Abstract
Only those aggregate sources which have been sampled or tested within the last ten years are listed. This listing additionally ranks sources in accordance with a skid resistance classification as defined herein for aggregates used in asphalt construction. The rankings are based on the ledges used in the past for asphalt aggregates. Upon request, new sources or different combinations of beds within an existing source will be evaluated as to their skid resistance classification. This ranking refers only to the skid resistant properties and does not waive the normal quality requirements for the particular type of aggregate indicated in the contract documents.
