Abstract:
Design criterea , calculations, construction procedures, stress measurements, and performance history are given for two, two-way prestressed overlay slabs installed on taxiway of San Antonio International Airport. 75 x 80-ft overlays, 4 in. thick, were placed on top of a damaged 6-in. slab. Pre-stressed levels were 425 psi and 175 psi; both overlays were in good condition after 3 1/2 years of service.
