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.
A hard surface would be necessary to keep the new equipment in a clean environment to improve the operating efficiency and lower maintenance costs.
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.
The Denver International Airport (DIA) Concourse C RON Project used 20,862 square yards of eight-inch roller-compacted concrete for pavement adjacent to the concourse apron areas. These are areas excess snow from around the DIA concourses is piled during heavy snow events.
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.
