Energy Applied To Motorways

Abstract
The environmental impact of roadways is considered really important.
Nevertheless, to establish a field of comparison some measures and parameters
are needed. Those parameters allow, first, to establish sustainable criteria to
develop new civil works, and secondly, they can suggest the best choice and
options for any particular case.
Sustainability itself and proper civil works are very complex concepts. The
present methodology establishes criteria which allow unifying this complexity
from a general point of view. As an example, this methodology will be applied to
find out an indicator which measures the embodied energy along all the life cycle
in the motorway. This indicator is open to be extended to and joined to other
indicators, to reach the whole scope of sustainability.
What is new in this methodology is the consideration of the motorway as a
whole dimension and scope, to research its whole life cycle. This means that the
aim is to include, in one single index, the embodied energy in the cycle of its
whole useful life (project, construction, maintenance and demolition) and in the
multiple aspects in which this index, including traffic, is appropriate. This
considers the energetic consumption produced directly or indirectly by:
- The act of construction and the materials used in highways, including
tunnels and all structures, and extra services and toll facilities.
- The energy utilized through management, periodic maintenance of all the
previously mentioned elements and the energetic consumption of all
vehicles that use the highway.
- The energetic implication in the deconstruction or demolition of the
highway, and the hypothetic recuperation of the natural space affected.
