RCC offers unique qualitiesdifferent from traditional concrete or asphalt that make the pavement an economical, fast-construction candidate for many applications previously reserved for asphalt or conventionalconcrete.RCC has been traditionally been used for surfaces carrying heavy loads at low speeds because ofits relative coarse texture, but in recent years RCC has been selected as the pavement of choicefor a greater number of commercial and industrial applications. Cities such as Columbus Ohiohave begun using Roller Compacted Concrete for residential streets, and Atlanta Georgia hasused RCC for interstate shoulder construction. RCC is primarily used in the construction ofindustrial and commercial parking areas and low traffic road surfaces.Typical applications of RCC include:Industrial access roads and parking areasShipping yards and portsTruck and freight terminals and distribution centersBulk commodity storage and compost areasAircraft parking areasUrban, rural and park roadwaysLarge commercial parking lotsTemporary travel lanesRCC is also being used in pavement systems for higher traffic speeds serving as base fortraditional concrete or the lower lift in a two lift paving operation.There are many benefits to the use of roller compacted concrete, but the main factor is the RCCcan be constructed faster and cheaper than traditional concrete and multiple lift asphaltpavements. RCC can be constructed fast because it is typically placed with asphalt type paverequipped with a standard or high density screed, then compacted with rollers. Unlike conventionalconcrete the use of forms, dowels, reinforcing steel and vibration are not used. Additionallytransverse joints are not required, however when project specifies they must be present the jointsare spaced farther apart than conventional concrete.The cost savings associated with RCC is attributed not only to the ease of construction, but thematerial also uses less Portland Cement the most expensive ingredient in conventional concrete.
The specific savings associated with the use of roller compacted concrete is dependent on thecomplexity of the construction, size of the project and specified mix design.Additional benefits of RCC - Roller Compacted ConcreteDurability and resistance to chemical attackHigh freeze-thaw durability even without the use of air entrainmentHigh strength capable of supporting heavy repetitive loads without failureReduced cracking and shrinkingRigid surface eliminating rutting except in areas of heavy tire chain or studded tire useResists abrasion even under heavy traffic loads and volumeLight colored surface reduces the required lighting for parking and storage areasLight vehicles and cars can travel on RCC soon after completionWhile the benefits of RCC are numerous it is important to understand there are also somelimitations to the use of roller compacted concrete. For example the production of large quantitiesof RCC requires specialized equipment. While a transit mix truck can mix RCC the mixing time issignificantly longer than conventional concrete and the amount of RCC than can be mixed in thetruck is reduced because the dryness of the RCC mix. Also the surface of RCC may not besuitable for high speed traffic without diamond grinding.Other limitations of RCCAdjacent slabs and multiple horizontal lifts must be place within an hour to ensure good bondingunless a cold joint is plannedPavement edges are more difficult to compact causing most specification to require 96% modifiedproctor density on cold jointsAdmixture usage on RCC may be higher than traditional concrete because of the dryness of thematerialRCC paving in hot weather requires extra attention to reduce the possibility of water loss andevaporationWhen considering the versatility of RCC, its ease of application in comparison to conventionalconcrete and its durability as compared to asphalt it becomes clear the roller compacted concreteis a suitable paving substitute. When considering the rising cost of oil and petroleum basedproducts such as asphalt it becomes clear that RCC is likely the paving material of the future.Matthew Gladen is the managing partner of FESCO Direct LLC. FESCO Direct LLC offers themost comprehensive line of RCC production equipment of any capital equipment dealer currentlyoperating in the US.Equipment available for the production of Roller Compacted Concrete from FESCO Direct LLCinclude a conversion trailer that when placed under any existing dry mix or ready mix concreteplant allows the production of RCC at the maximum production capacity of the concrete plant or200 cubic yards per hour what ever is lowest.
