Abstract:

In October 1986, a 16,500-sq-yd roller-compacted concrete RCC pavement tank hardstand was constructed at Harvey Barracks in Kitzingen, West Germany. This report discusses the effects of the construction process, particularly the laydown and compaction, on the strength, density, smoothness, and surface texture of the RCC pavement hardstand at Kitzingen. The strength of the RCC was measured by conducting flexural and splitting tensile tests on beams and cylinders fabricated in the laboratory and extracted from the pavement. From the fabricated beams it was determined that the flexural strength decreases with decreasing density. The density of the RCC pavement was measured by conducting nuclear density gauge tests on the in situ RCC and by extracting cores from the pavement and determining the unit weight.
