Objectives: The long-term goal of this effort is to develop a device that will measure, at highway speeds, pavement structural condition which is known to impact the performance of PCC and composite pavements. Such a system needs to be able to process the collected measurements into an immediately usable form in near real-time. It is believed that the recent improvements in computers, laser measuring devices, and similar technologies will make the development of such a system possible. The goal of the work specifically described herein is to, in fact, determine if the required technologies exist and to what extent a market exists for such a device. Scope: The proposed research project will investigate the feasibility and practicality of developing a device for measuring the structural condition of PCC and composite pavements.
