Roller Compacted Concrete (RCC) is a durable, economical and sustainable pavement solution, which gets its name from the heavy vibratory and rubber-tired rollers used to compact its final form. RCC is a heavy-duty pavement, used when large paved areas must stand up to heavy vehicle loads, abrasive environments and sharp turning movements, as well as, hydraulic and oil spills and specialized equipment.
Below is a table entitled Roller-Compacted Concrete (RCC) Performance identifying the features and benefits of RCC.
Features | Benefits |
High flexural strength (500 psi (3.35 MPa) to 1,000 psi 6.9 MPa) | Supports heavy, repetitive loads without failure and spans localized soft subgrade areas, which reduces maintenance costs and down time. |
High compressive strength (4,000 psi (27.6 MPa)to 10,000 psi (69 MPa)) | Withstands high concentrated loads and impacts from heavy industrial, military, and mining applications. |
High shear strength | Eliminates rutting and subsequent repairs. |
High density, low absorption | Provides excellent durability, even under freeze-thaw conditions; eliminates seepage through pavement. |
Low water content, low water/cement ratio | Increases strength, reduces permeability, and enhances durability and resistance to chemical attack. |
Aggregate interlock | Provides high shear resistance at joints and uncontrolled cracks to prevent vertical displacement or faulting. |
No steel reinforcing or dowels | Speeds and simplifies construction, reduces costs. |
No forms or finishing | Speeds construction, reduces cost, minimizes labor. |
No formed or sawed joints | Speeds construction, reduces cost. (To enhance appearance, joints can be sawn into RCC pavement.) |
Hard, durable, light-colored surface | Resists abrasion, eliminates need for surface course and reduces cost. The light color reduces lighting requirements for parking and storage areas. |
Typical applications for RCC include industrial pavements and heavy-duty parking lots, in addition to several specialized uses in ports, intermodal yards, snow melt sites, scrap metal facilities, and dams.
