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
