Abstract:The Texas Department of Transportation (TxDOT) is presently using a quality control/quality assurance specification for hot-mix asphalt concrete pavement. There is a strong interest in determining if other construction items can be converted to this type of specification. The purpose of this report is to (1) review the experiences of a large number of key states believed to be using these types of specifications, (2) review the TxDOT standard specifications in order to recommend candidates for development, and (3) develop a recommended QC/QA specification for flexible base. Of the twenty-three states contacted, nineteen cooperated in the survey, the majority of which were willing to provide copies of their specifications. Fifteen specifications have been received. Based on the information obtained from these reviews, nine items have been recommended for consideration by TxDOT.
