Concrete Historical Timeline • 3000 BC -476 AD
Performance • Long service life - 40 years or more • Resists oil, chemicals and weather • Withstands heavy axle loads without rutting • Unaffected by high temperatures
Safety and the Environment • Built-in skid resistance and traction • Can be grooved for water run-off • preventing aquaplaning in wet conditions • Even-riding, smooth texture • Integral rumble strips can be installed • Can be recycled
Construction • Fast-track techniques enable early completion • Ie: One-pass completion • Hot and cold weather placement
VERSATILITY • Aesthetic appeal • stamping/finishing options • Cost-effectiveness • structure elements can be architectural also • Cost-effectiveness & availability
Other Structural Benefits • Reduced sound transmission • Fire resistance • Lower Energy Costs
