Township is first in Pennsylvania to use RCC| Public ,
The savings add up Using RCC instead of conventional pavement saved the township 30% on initial cost due to: The overall pavement depth is 10 ½ inches, compared to the 16 ½ inches it would have been with traditional asphalt pavement
CN102659355A - High frost resistance roller compacted ,
The invention relates to a high frost resistance roller compacted concrete mortar wrapped stone mixing method which is suitable for the field of construction of high frost resistance roller compacted concrete in a cold region The high frost resistance roller compacted concrete mortar wrapped stone mixing method comprises the steps of: ,
Roller compacted concrete (RCC) is a concrete mixture with a low cementitious material and water content and a dry consistency It is placed using an asphalt paver and consolidated using roller compaction This zero-slump concrete does not require slip-form conventional concrete paving equipment for .

Then there’s cellular, cork, roller-compacted, glass, asphalt concrete types—endless possibilities to choose from Talk to a concrete specialist to see which is best for your project Concrete Calculation
Determining optimal combination of roller compacted ,
The present study investigates the effectiveness of evolutionary algorithms such as genetic algorithm (GA) evolved neural network in estimating roller compacted concrete pavement (RCCP) characteristics including flexural and compressive strength of RCC and also energy absorbency of mixes with different compositions
Roller Compacted Concrete (RCC) is a relatively stiff, zero-slump concrete mixture with the consistency of damp gravel and compressive strengths greater than 4,000 psi RCC can be made using local materials, aggregates or crushed recycled concrete, Portland cement and/or fly ash, and water

3 Roller compacted concrete (RCC) is a relatively stiff mixture of aggregate, cementitious 4 materials and water that is placed using asphalt pavers, compacted by vibratory rollers and 5 hardens into concrete ( 1 )
ROLLER EFFICIENCY and CONTACT PRESSURES , compaction In this example , compacted in 6 to 8 inch lifts, so can settle noticeably The diesel powered Ramex P/33 Trench Compactor is hand-operated and used in trenches and difficult access areas These walk-behind and remote controlled compactors weigh about 3000 lbs and were ,
Low Fines Content Roller-Compacted Concrete | Airfield ,
Roller-compacted concrete (RCC) is re-emerging as an alternative pavement type to asphalt concrete and even slip-form concrete pavements because of its rapid construction, early opening to traffic, and its economic benefit The lower cement content of RCC requires careful selection of the aggregate .
Typically, fly ash is added to structural concrete at 15-35 percent by weight of the cement, but up to 70 percent is added for mass concrete used in dams, roller-compacted concrete pavements, and parking areas Special care must be taken in selecting fly ash to ensure improved properties in concrete
