State of the Art of Pavement Response Monitoring Systems for Roads and Airfields Symposium. Held in West Lebanon, New Hampshire on March 6-9, 1989.

摘要

Pavement Instrumentation, although proven to be of great benefit in understanding pavement response and in setting design criteria, has not been applied routinely. There may be several reasons for the infrequent use of instrumentation. For example, early instrumentation was difficult to install and sensitive to installation and use. The failure rate required, significant redundancy. Installation, maintenance, data collection and data reduction were expensive. Therefore, benefits compared to costs were considered marginal. Analytical methods were considered in many cases adequate to estimate pavement responses due to the effects of load, climate and materials, etc. In a number of cases the problems of data reduction and analysis overwhelmed researchers. As a result, manual techniques were often relied upon to obtain results. These data often have been filed without complete analysis. Starting in about 1985 several U.S. Highways agencies initiated research projects with pavement instrumentation.
