This paper reports on the variability of concrete strength of four road structures in Thailand as measured using the rebound hammer during an in-situ investigation. Results from all four structures are first examined using basic descriptive statistics; then, for a selected structure, both comparative and spatial analyses are carried out to examine the variability within a single component.
