Abstract:

The U. S. Army Corps of Engineers has begun using roller compacted concrete for construction of heavy-duty pavements and low volume streets and roads which are exposed to low-speed tracked and rubber-tired vehicular traffic. The pavements must withstand numerous application of fuels, oil, deicing solutions, washwater, and other chemicals which accompany the routine operation and maintenance of military equipment. The U. S. Army Engineer Waterways Experiment Station (WES) has proportioned the RCC mixtures used or to be used in five pavements at various U. S. Army installations. Aggregates used in the mixtures included crushed stone and uncrushed gravel, and manufactured and natural fine aggregate. The water-cement ratios (w/c) of the mixtures ranged from 0. 21 to 0. 39 by mass, and all but one of the mixtures contained either Class C or F fly ash.
