摘要

Many actions are being undertaken by Norwegian road owners to reduce the environmental impact of construction and maintenance of pavements. Thanks to the collaboration with the local contractors association, a new procurement system, based not only on the financial cost of maintenance operations but also on CO2eq emission, has been introduced. In three years, it has already led to a 30% reduction of CO2eq emissions in maintenance projects. In addition, an analytical pavement design and analysis system, built to consider the local conditions (available materials, traffic loads, climate), will soon juxtaposed to today’s guidelines based on empirical methods. It will facilitate not only the use of customized solutions but also the prediction of the pavement service life. Through the introduction of more flexible and performance-oriented procurement and design systems, the aim is to increase the consultants and contractors’ freedom in choosing the right solution, as far as the environmental and economic impact are balanced with the expected service life; the final purpose being encouraging the technological advancement needed to achieve the common climatic goals. This paper intents therefore to evaluate the progress and consequences of the Norwegian pavement sector’s strategy for a more sustainable infrastructure.
