Construction of infrastructures such as highways generates huge volume of various by-products. In the present study, an estimation system of the emissions, including those from other related economic activities, for a life cycle of an infrastructure project has. been developed. The main part of the system is an extended Input-Output model, which deals processes of construction material production and by-product recycling. The system was applied to alternative route plans of a highway development, and it was revealed that the amount of final wastes are strongly depend upon the types of road structure.Reusable aggregates collected from the road works has been estimated by asystematic method based on statistical data. It suggests that in the near future the quantity of aggregates collected will supply a demand for road works.
