Abstract
The most well-known and used evaluation system to determine the life cycle of a product, is the life cycle assessment (LCA). In Europe, the use of the life cycle assessment (LCA) to assess the environmental performance of products is becoming commonplace, which is why substantial efforts have been made in the last two decades to develop new life cycle assessment (LCA) methodologies and software. This paper evaluates the life cycle assessment (LCA) for the rehabilitation of a national road sector in Romania. The biggest ecological problem facing mankind is the effect of global warming and climate change associated with this phenomenon, due to the increase of the concentration of pollutants to the atmosphere, and this paper presents the results of the life cycle assessment (LCA) based on a cradle-to-gate approach. For this case study, were used three rehabilitation alternatives. These alternatives and the existing pavement structure were analysed using the GaBi software, Ganzheitlichen Bilanzierung (German for holistic balancing), to assess the environmental impact of global warming, the stratospheric impact of ozone, and the impact on human health. The results obtained in this study illustrate the importance of a life cycle assessment approach for evaluating the sustainability for different designs and for the construction of road rehabilitation options.
Highlights
Academic Editors: Diego Gino andThe life cycle analysis of a product or service is a process with high applicability, making it possible to assess the flows of the materials, energy, and waste of a product over the entire life cycle of the product or service, and its impact on the environment.The analysis covers the complete life cycle of a product, process, or activity, including the production of raw materials, manufacturing, transport and distribution, use, reuse, maintenance, recycling of materials, and final disposal or destruction
The environmental impact assessment has become a key factor in the design and the construction of infrastructure works [2,3,4]
The purpose of the study is to outline an overview of the life cycle analysis of a road sector that is part of the Romanian national road DN73, between km 111 + 000 and km 120
Summary
The analysis covers the complete life cycle of a product, process, or activity, including the production of raw materials, manufacturing, transport and distribution, use, reuse, maintenance, recycling of materials, and final disposal or destruction. The life cycle analysis for construction evaluates the impact of a structure over its lifetime. The environmental impact assessment has become a key factor in the design and the construction of infrastructure works [2,3,4]. The materials may be reused whole or in part, if appropriate disposal techniques are applied. This procedure is one of the keys to sustainability. A road is different from many other products in that production methods, material consumption, etc., vary significantly
