Performance

Long service life - 40 years or more
Strength increases with age
Resists oil, chemicals and weather
Withstands heavy axle loads without rutting
Resists subgrade failure - spreads wheel loads
Unaffected by high temperatures
Concrete inlays and overlays -ideal options for rehabilitating flexible pavements

Safety and the environment

Excellent light reflection providing greater visibility
Built-in skid resistance and improved traction, for safer driving
Can be grooved for improved run-off, preventing aquaplaning in wet conditions
Even-riding, smooth texture - no rutting or "shoving"
Integral rumble strips can be installed
"Whisper" concrete can control noise levels in urban areas
Locally available raw materials - cement, sand, stone and water
Can be recycled saving scarce resources

Construction

Fast-track techniques enable projects to be completed faster - opening to traffic in 12 hours is possible
Labour intensive methods can be applied, empowering local communities and creating employment
One-pass completion
Hot and cold weather placement
Concrete plants can operate all year round

Economy

Comparable initial costs for equal designs in other materials
Competitive life-cycle costs (costs for whole life of the road - including maintenance)
Low maintenance and low road-user disruption costs
Reduced lighting costs due to excellent surface reflectivity
Minimal wear and tear to vehicles
