ADVANTAGES OF RCCADVANTAGES OF RCC

•CostMaterials, placement methods, speed and durability 

•Speed of construction Higher strengths earlier then typical conventional concrete 

•DurabilityLife cycle of conventional concrete > longer lasting then asphalt  

•Sustainability Life cycle, heat island effect, lower lighting costs, emissions from 

i lraw materials 

ALL THESE ADVANTAGES ARE IMPORTANT TO RSI CLIENTS. ONE OR MORE OF THESE REASONS WILL SALE RCC OVER ASPHALTMORE OF THESE REASONS WILL SALE RCC OVER ASPHALT
