Roller Compacted Concrete
RCC Pavement
• No Slump
• Consistency of damp gravel
• No forms
• No reinforcing steel
• No finishing
• Placed with asphalt pavers
• Compacted with vibratory rollers
• Normal cement hydration
• Low W/C ratio = limited shrinkage cracks

RCC Construction Process
•Mid size applications
•200 to 300 tons/hr
•Available at some locations
•Fixed locations
•Capacity reduced due to low
water content of mixture
Central Mix

RCC Construction ProcessAsphalt Paver Placement
• High density
• High initial density (85% to 95%)
• Smooth surface depends on initial density
• High-production (1900 LF/day)
• Max lift thick – 8 to 10 in. Lane Ave – Columbus, OH

RCC Construction ProcessAsphalt Paver Placement
• Proper compaction is critical for strength and durability
• Compact to 98% of modified proctor
• 10 to 12 Ton vibratory roller
• Eliminate long. cold joints through compaction process
