EVALUATING FACTORS IN SUSTAINABLE ROAD CONSTRUCTION AND MANAGEMENT ± A LIFE CYCLE APPROACH

摘要: Roads perform an important connecting function for the community. At same time their design, construction and operation are not always easy from point of view sustainability. Achieving sustainability in this process requires undertaking initiatives such as sound environmental management, water sensitive urban use advanced recycled materials, environmentally responsible project management construction. The contribution factors to a particular road can be different alternative options constructing managing road. This issue comparing these options. A methodology is proposed address through calculating weighted score related economic, social each option, using life cycle approach that considers stakeholder requirements. As variables tend measured range units may either quantitative or qualitative, variable given option both weight also assigned suitable comparative obtained though calculation variables, utility qualitative variables. calculated total scores various then compared when assessing most sustainable option. An example compares two provided. described flexible used conjunction with other methodologies, capable being developed into computer based modelling tool.
