Instrumented couplers and Carlson strain meters are a satisfactory means of extracting data from the pavement. It would appear that after two years of life, however, and after many of the couplers are no longer providing data, that in future prestressed pavement work the trumpets or sheaths surrounding the instrumented couplers should be much longer than were used at NAS Lemoore to obviate the possibility of the coupler binding on a trumpet end when the prestressing tendons are stretched.
