A core-ring strain gage (CRSG) test procedure has been devised for measuring the
residual stress in a concrete pavement. Initially cantilevered concrete beams were
selected for instrumentation to determine if beam stresses could be released and measured by drilling a core-ring. The known load induced stresses for a cantilever beam, before a core-ring is drilled, have a theoretical solut…
