ACI 117-10(15) provides tolerances for core test and impact-echo thickness measurements. These measurement techniques as well as laser scanning and ground-penetrating radar were used to collect thickness data from a slab-on-ground test panel. The data was then analyzed to determine appropriate average and individual thickness tolerances for all these test methods.
