Environmental Assessment of Rural Road Construction in India
Construction of road pavement consumes significant quantities of raw materials and energy and involves use of heavy machineries. In India, total length of road network is 6.38 million km, out of which highest share (71%) is that of the rural roads. The main aim of this chapter is to present the development of detailed life cycle inventory for material phase and construction phase of rural road pavement, followed by evaluation of their environmental impacts. The scope of the study included the raw material extraction, the transportation of raw materials to the site and the construction of rural road using heavy machineries for a typical rural road section in Bihar, India, using GaBi software version 10.5. Maintenance and end-of-life phases were beyond the scope. The functional unit adopted was 1 km of road pavement constructed. A total of seven impact categories were considered. The pavement was constructed in three layers viz. granular sub-base layer, water-bound macadam layer and top bituminous layer. It was found that the granular sub-base layer construction had the highest contribution towards the impact on environment for all impact categories due to the high consumption of aggerates.
