Cement Concrete

Concrete is a very durable material for the construction of roads and highways. Cement concrete has been used for the construction of new roads, highways and also for the rehabilitation of existing distressed bituminous pavements. Several highways, expressways and city roads have been constructed with cement concrete in the recent past in India. Cement concrete roads offer long life of more than 30 years with minimum maintenance requirement. Rutting of bituminous pavement is a real problem in hot climate like India, with heavy truck loads, operating under frequent start/stop conditions. It is commonly applied where rutting of bituminous pavements is a recurring problem. Concrete overlays offer the potential for extended service life, increased structural and functional capacity, reduced maintenance requirements, and lower life-cycle costs when compared with bituminous overlay alternative.
