Construction of Green Field Expressway

By Accommodation Times (

The choice of cement concrete pavement over bituminous pavement depend upon various factors, such as sub-grade soil, rainfall, traffic volume, availability of construction materials, besides costs, etc. Accordingly, the choice of pavement type for development of green field expressways may vary from project to project.
Cement concrete roads have more life span compared to bituminous pavement; but the same could not be quantified. However, the concrete roads also have their inherent limitations, such as higher initial cost, poorer riding quality at joints and more noise due to traffic as compared to bituminous pavements. Further, stage construction is not possible in case of concrete roads.
The Government has approved construction of 1,000 km of Expressways under the National Highways Development Project (NHDP) Phase-VI. The following stretches have been identified under NHDP-Phase-VI:-

. Section Length (km)
1 Vadodara—Mumbai 400
2 Bangalore—Chennai 334
3 Delhi—Meerut 66
4 Kolkata—Dhanbad 277

This information was given by the Minister of State of Road Transportand Highways, Shri Jitin Prasada, in a written reply in Rajya Sabha today.
