STATE-OF-THE-ART IN ASPHALT PAVEMENT SPECIFICATIONS

The great increase in highway construction beginning in the 1950's made evident the need for better control of materials and construction. A comprehensive research and development program was begun to use statistical methods for quality assurance in highway construction. The effort since has resulted in quality control and acceptance plans which are used in specifications to somm degree by more than 30 states. The quality assurance specifications usually assign the responsibility for control of materials and construction to thee contractor. Acceptance and method for pay adjustment for non-compliance are highway agency responsibilities; surveys show a wide disparity in pay adjustment factors. Performance-related specifications based on distress modes and contributing factors are also described. Studies indicate that the most predominant forms of distress are cracking (load and non-load), distortion, disintegration, roughness and reduced skid resistance. Contributing material factors and evaluation methods are outlined for each of the performance-related distress modes. The report also summarizes the problem of reflection cracking, its contributing factors, and methods of overlay design and special treatments to prevent or minimize this form of distress condition. Recommendations are to encourage the effort to continue development of quality assurance specifications based on sound engineering judgment and to develop detailed performance-related specifications with optimum mix-design requirements to meet the need for structural capacity, rideability and skid resistance.
