Pavement Evaluation: Phase I. Pavement Evaluation Equipment
The study determined the most promising kinds of equipment to develop for evaluating the structural condition of pavements. In order to decide what needed to be measured in determining the structural condition of a pavement, all 50 states, some Canadian provinces, and some city and county agencies were asked to name the factor they consider to be important in their assessment of pavement condition. Results of this survey of current pavement condition rating methods are included. The two most important variables were found to be stiffness and cracking. Highway equipment reviewed include static deflection, steady-state vibration, impulse, and wave propagation techniques. Non-highway equipment include acoustic holography, infrared microscope, vibroseis, photo diode scanners, microwave sensing, and the duomorph. Several types of measurement and analysis schemes were proposed. Ten pieces of equipment were recommended for future development, two of which were to be developed in Phase II of this study: the duomorph and the mobile acoustic crack detector.
