084-‐LCA of concrete and a sphalt pavements: a case study in the province of Quebec (Canada)
§ Pavement construcGon and maintenance are crucial because of : • The increase of heavy traffic volume • Severe ambient environment
§ Two main alternaGves for paving the roads
Asphalt
Concrete
Scope of the phase I of the project: What are the contribuGons of the different life cycle stages on the final results? To find out which alternaGve has the least potenGal impacts in high level of traffic servicing in Quebec.
