8. Roller Compacted Concrete – Placement Method
• RCC is transported by dump trucks from the pugmill
paver.
• It is placed in lifts between (100-250mm) thick and
wide.
• Compaction using steel drum vibratory rollers begins
immediately after placement and continues until the
pavement meets density requirements.
• RCC does not require the internal vibration
• Curing is an important step to protect from moisture
and to ensure adequate strength gain and durability.

10. Advantages of Roller Compacted Concrete (RCC) Concrete
• Reduced cement consumption as the leaner concrete mix can
used.
• Formwork costs are minimized or eliminated because of the
placement method.
• No concerns about high heat release while the concrete is
• The cost of transporting, placement, and compaction of
are minimized because concrete can be hauled by dump
• Spread by bulldozers and compacted by vibratory rollers.
• This concrete solution can be used to maintain traffic open
large volumes of RCC can be placed easily.

11. Roller Compacted Concrete (RCC ) Applications
• Port, rail and military facilities
• Distribution centers, parking and storage facilities
• Streets & highways, intersections, shoulders, turn lanes, bike
• Manufacturing facilities, heavy haul roads, scrap yards
• Power plants and other industrial facilities
• Other secondary RCC applications
• Over-topping protection
• Embankment dam raise
• Reservoir liners
• Industrial slab floors
• Airfield maintenance areas

12. Limitations of Roller Compacted Concrete (RCC)
•
The surface of RCC is rougher than other pavements and not
suitable for high-speed traffic.
• The construction of adjacent slabs and also multiple
in same layer shall be placed within an hour to make sure the
bonding between layers.
• It is very difficult to compact the pavement layer towards the
• The use of admixture on RCC may be higher than
concrete pavements because of the dryness and stiffness of
mixture.
• In hot weather concreting of RCC for paving requires
attention to decrease the possibility of water loss due to
evaporation.

13. • Typical surface texture before roller compaction

14. • Typical surface texture after roller compaction

16. Construction Process
• RCC discharged from a transit mixer truck to a dump truck
transportation.

21. • 10-ton roller in action, taking care of the compaction.

22. • Roller compacting the fresh joint.

30. Longitudinal joint construction in RCC pavement.
Vertical Cold Joint

31. Fresh Joint

32. Angular Cold Joint

37. • Method to improve RCC finished surface.

38. • Heavy duty RCC pavement constructions

39. Foundation of Shri Ram Janmabhoomi Mandir, has been
decided that foundation work will be done using Roller
Compacted Concrete technique.

43. • Total 40-45 layers of concrete will be put in
1,20,000 sq feet area.
• It takes 4-5 days to put one layer .
