16. Life Cycle Impacts of Road Infrastructure : Assessment of energy use and greenhouse gas emissions
Sammanfattning : Road infrastructure is essential in the development of human society, but has both negative and positive impacts. Large amounts of money and natural resources are spent each year on its construction, operation and maintenance. Obviously, there is potentially significantenvironmental impact associated with these activities. LÄS MER
17. Towards Sustainable Construction: Life Cycle Assessment of Railway Bridges
Sammanfattning : Since last few decades, the increased pressure from the environmental issues of natural resource depletion, global warming and air pollution have posed a great challenge worldwide. Among all the industrial fields, bridge infrastructures and their belonged construction sector contribute to a wide range of energy and raw materials consumptions, which is responsible for the most significant pollutions.
