Roller-Compacted Concrete (RCC) Case Histories
In the fourth quarter of 2012, the Georgia Port Authority elected to expand the capabilities of its Ocean Terminal off the banks of the Savannah River in Savannah, Georgia, and provide more storage for the loading and offloading of medium duty cargo.
In 1974, when the South Carolina Department of Transportation (SCDOT) built the J.A. Cochran Bypass in an undeveloped area around Chester, South Carolina, minimal traffic used the route. Today, the bypass serves as a major truck route shortcut between two interstates and connects to Chester’s main shopping area, all making it the second busiest road in Chester County.
Local NRMCA member Sequatiche Concrete Services provided roller‐compacted concrete (RCC) paving material for the new Marion County Regional Institute of Technical Excellence in Kimball, Tennessee.
Automakers have used roller-compacted cement (RCC) for its low cost, high construction speed, high strength and low maintenance in parking areas and access roads. The latest example is the use RCC is Volkswagen at a plant in Chattanooga, Tennessee.
The job called for a pavement that could economically cover large areas of at least 10 acres, and hold up to heavy-duty abuse from large equipment.
Roller-compacted concrete is often the material of choice for this type of application because of its high strength and durability, and large areas can be constructed with significant cost savings.
The City of Columbus, Ohio, and nearby municipalities, have experienced a rapid growth in recent years in the use of roller-compacted concrete for their city streets.
Fort Carson, the army’s mountain post located outside Colorado Springs, Colorado, is the latest military facility to utilize rolled-compacted concrete pavements at its facilities. As part of an expansion program at the post, RCC is being used to pave the tank hardstands of several new maintenance facilities, as well as a 1.6 mile tank trail.
The speed of construction, durability, and economy offered by roller-compacted concrete pavement are attributes that made it a long-term solution for GDOT pavement management.
The South Carolina Department of Transportation (SCDOT) recently witnessed the versatility of roller-compacted concrete along US-78 near Charleston. To repair a heavily rutted five-lane section, the SCDOT decided to use a semi-rigid pavement system composed of two inches asphalt surface and10 inches of RCC as a base to repair the roadway and eliminate any future rutting.
The use of RCC for pavements at industrial facilities such as port and intermodal container terminals is particularly appropriate because of its ability to construct low-cost concrete pavements over large areas, allowing flexibility in terminal operations over time.
Owners of a paper mill in coastal Maine decided in September 2006 that a hard surface was needed in a yard area where new process improvements were being installed.
For the DIA Concourse C RON Project, 20,862 square yards (17,443 square meters) of 8-inch (200 mm) roller-compacted concrete (RCC) was selected for the pavement adjacent to the concourse apron areas.
RCC’s combination of strength, durability, speed of construction, and economy continues to meet the growing need for value added pavements in the industrial sector.
Roller-compacted concrete (RCC) was the material of choice to buttress Loch Raven Dam, almost a century old cyclopean concrete structure. The RCC rehabilitation, project initiated in 2002, brought the dam into compliance with current safety requirements and significantly increased its spillway capacity.
It was determined that construction of a new RCC dam downstream of the old dam and raising the permanent lake elevation 7 ft (2.1 m) to increase water supply was the preferred alternative to stabilizing and raising the existing dam.
Based on the results of the geotechnical investigation and hydrologic/ hydraulic analyses, an RCC dam with a conventional concrete spillway was selected as the preferred alternative.
The new dam is a roller-compacted concrete (RCC) gravity structure approximately 86-feet-high (26.2 m) at its maximum section with a crest length of approximately 560 feet (170.7 m).
Hickory Log Creek Dam is a 180-ft (55-m) high, 956-ft (291-m) long RCC gravity dam. The dam will impound a 411-acre (166-hectare) reservoir with a supply capacity of 44 mgd (167 mld).
Elkwater Fork Dam is a new roller-compacted concrete gravity dam located in Randolph County, West Virginia. The Elkwater Fork Dam site was identified as part of a county-wide water resources study completed in the late 1990s by the Natural Resources Conservation Service in Morgantown, W.V
