Features
|
Benefits
|
|
High flexural strength
(500 to 1,000 psi)
|
Supports heavy, repetitive loads without failure and spans localized soft subgrade areas, which reduces maintenance costs and down time.
|
|
High compressive strength (4,000 to 10,000 psi)
|
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.
