Nick Savko & Sons, Inc. has completed over 500 roller compacted concrete (RCC) jobs, since first introducing RCC pavement in 2001.

Roller compacted concrete pavement has many uses including the rebuilding of residential streets for municipalities, as well as commercial applications in paving parking areas, truck docks and structural sub flooring in warehouses and distribution centers, to name just a few.Savko continues to find new applications for RCC, and use this technology along with it portable pug mills to pave a 71-acre intermodal facility for Norfolk Southern Railroad at the Rickenbacker Airport, just south of Columbus, Ohio.The advantages of RCC are numerous. In addition to the benefits of 2-hour vehicle, higher flexural and compressive strengths, and major cost savings on material and labor, RCC pavements eliminate common and costly problems long associated with asphalt pavements.

| RCC Pavement Concrete Performance | |
| FEATURES: | BENEFITS: |
| Higher flexural strength (500 to 1,000 psi) (3.5 MPa to6.9 MPa) |
Supports repetitive heavy loads; concrete pavement can span localize soft subgrade areas reduces maintenance |
| Higher compressive strengths (4,000 to 10,000 psi)(28 MPa to 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, and Low absorption | Provides excellent durability, even under freeze-thaw conditions; eliminates seepage through pavement |
| Low water content, low water / cement ratio | Increase 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 and reduces cost |
| No forms or finishing | Speeds construction, reduces costs and minimizes labor |
| No formed or sawed joints | Speeds construction, reduces costs. To enhance appearance, joints can be sawn into RCC pavement |
| High durability light colored surface | Resists abrasion, eliminates need for surface course and reduces costs. The light color reduces lighting requirements for parking and storage areas |
