Environmental data of cold mix using emulsified bitumen for a better selection of road materials

This paper reports the result of a study on the environmental impact of road construction techniques with bitumen emulsion. It describes the methodology used for data gathering in quarries for aggregates manufacturing, in emulsion plant, and in mixing plant during grave-emulsion manufacturing. Then calculations are performed with the IFSTTAR software ECORCE to compare a cold mix (grave-emulsion) with conventional techniques as Hot Mixes Asphalts. These calculations was limited to overall indicators (GreenHouse Gas emissions, energy and natural resources consumption) and validate favorable considerations on cold road construction techniques. Finally a sensitivity study shows the great influence of parameters as binder content, void content and transportation distances on environmental assessment of grave treated with bituminous emulsion.
