    • Roller Compacted Concrete
      What is Roller Compacted Concrete (RCC)
      Where has RCC been used
      RCC Construction Process
      50th Street & Grape Creek Bid Tab
      Street Life Cycle
    • 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
      Reynoldsburg, OH
    • RCC Construction Projects
      Street Projects
      Collector & Residential
      Several in S. Carolina
      100+ in Columbus, OH

      • RCC selected for fast
      construction process to
      complete by 1st football game
    • RCC Construction Process
      Central Mix
      • Mid size applications
      • 200 to 300 tons/hr
      • Available at some locations
      • Fixed locations
      • Capacity reduced due to low water content of mixture
    • RCC Construction Process
      Continuous Flow Pugmill
      • High-volume applications
      • Excellent mixing efficiency for dry materials
      • 250 to 900+ tons/hr
      • Mobile, erected on site
      • Mobilization costs
    • RCC Construction Process
      Asphalt 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 Process
      Asphalt 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
