Abstract:
Members of ACI Committee 330 have questioned the applicability of ACI 117-10(15) tolerances for concrete slabs-on-ground (typically interior slabs with horizontal top and bottom surfaces) for sloped slabs-on-ground. The article discusses thickness variations evaluated for 32 slab-on-ground parking lot pavement placements. Based on the data, the authors propose thickness tolerances for adoption by Joint ACI-ASCC Committee 117 and ACI Committee 330.
