Roller compacted concrete (RCC) for pavements combines the technologies of cement treated aggregate base, (soil cement), and portland cement concrete, to produce a rigid slab of moderately high strength capable of carrying heavy wheel loads. Aggregate should be well graded gravel or crushed rock, 100% passing the 7/8 in. (22 mm) sieve. Fine aggregate up to 14% passing the #ZOO (75 ym) sieve is acceptable. Roller compacted concrete for heavy duty pavement has been used in British Columbia since 1976. The first installation was a 4 acre (1.6 hectare) log sorting yard on Vancouver Island. Since that time ten other RCC heavy duty pavements have been built. In 1983 a coal storage area using RCC was the first project in a severe winter climate. In 1985 RCC was used for container storage areas in Houston, Texas and Tacoma, Washington. The U.S. Army Corps of Engineers built heavy duty RCC pavements to carry military vehi-cles at Fort Hood, Texas and Fort Lewis, Washington. An aircraft parking area was built at Portland, Oregon - the first use at an airport. This paper will review some of the most significant projects that have been built since 1976 and describe the construction proce ss.
