Previous BTCE work (Report 94) has established that reductions in pavement roughness reduce fuel consumption, greenhouse gas emissions (end-use only) and vehicle operating costs. This Paper evaluates the effects on greenhouse gas emissions and vehicle operating costs of reducing the roughness of the National Highway System and the Pacific Highway over the period 1996–2015. The analysis takes account of the emissions involved in the production, transport and application of road rehabilitation materials. Some results of case studies of recently completed highway rehabilitation projects are included in the Paper.
