Sustainable design and construction elements in green highway

Abstract

Sustainable development principles have been implemented in various sectors including construction. Proper development and operation of infrastructure projects such highways can contribute significantly to the mission of sustainable development. Previous studies shown that most of conventional highways are unsustainable in many ways. Highways are facing severe challenge such as deteriorating condition, congestion, energy supply, and shortfall of funding for maintenance and capacity expansion to meet increasing demand. However at the same time, they consume huge amount of natural minerals and energy and generate waste and emission which contributing to climate changes and global warming. Therefore, sustainable design, construction, operation and maintenance have become priority these day. The aim of this paper is to determine critical elements for sustainable design and construction based on ranking of the priority level of the weighted value of each criteria. The questionnaires survey were developed and distributed to related respondents in order to obtain the agreement level for the element. The data was analysed using SPSS with factor analysis method. Result from the analysis shown the criteria, weightage and score for main criteria for sustainable design and construction activities for green highway.
