MEASURING PAVEMENT STRAIN USING DIFFERENT STRAIN MEASURING DEVICES . THIRD INTERNATIONAL CONFERENCE ON BEARING CAPACITY OF ROADS AND AIRFIELDS. PROCEEDINGS, NORWEGIAN INSTITUTE OF TECHNOLOGY, TRONDHEIM, NORWAY, JULY 3-5 1990. VOLUMES 1-2

This paper discusses the statistical analysis of the strain data collected from three different types of asphalt concrete strain gauges; each type has its own design, operations and installation techniques. The gauges were installed at the test track at Pennsylvania State University, USA, in two newly constructed sections: (1) a thin section (6 inches of asphalt concrete over 8 inches of crushed aggregate); (2) a thick section (10 inches of asphalt concrete over 10 inches of crushed aggregate). The loading of the test sections was conducted with a single-axle tractor and a tandem-axle trailer combination. Linear regression analyses of the measurements were performed, to estimate the correlation between the responses of the individual gauges and the overall average of all the tested gauges. The following conclusions were drawn: (1) the Dynatest gauges performed very well under all conditions, except that two of them failed in the thick section; (2) the Kyowa gauges performed as well as the Dynatest gauges, even though they were ten times less expensive; (3) the core gauges performed satisfactorily but not as well as the other gauges, and they seem to require a better installation procedure. However, a very important advantage of the core gauges is that they can be retrofitted. (TRRL)
