Determining the Environmental Benefits of Ultra High Performance Concrete as a Bridge Construction Material.
Vis sammendrag
Ultra High Performance Concrete (UHPC) is a material that is attracting attention in the construction industry due to the high mechanical strength and durability, leading to structures having low maintenance requirements. The production of UHPC, however, has generally higher environmental impact than normal strength concrete due to the increased demand of cement required in the concrete mix. What is still not sufficiently investigated, is if the longer lifetime, slimmer construction and lower maintenance requirements lead to a net environmental benefit compared to standard concrete bridge design. This study utilizes life cycle assessment (LCA) to determine the lifetime impacts of two comparable highway crossing footbridges spanning 40 meters, designed respectively with UHPC and normal strength concrete. The results of the study show that UHPC is an effective material for reducing lifetime emissions from construction and maintenance of long lasting infrastructure, as the UHPC design outperforms the normal strength concrete bridge in most impact categories.

Modelling solutions for implementing life cycle environmental impacts in road construction in the procurement process: A case study in Norway.
Vis sammendrag
The current public road network in Norway is being upgraded with new ambitious road projects to meet today’s standards. At the same time, the Norwegian National Public Roads Administration (NPRA) has committed to reducing the life cycle GHG emissions of new built infrastructure by 40% by the year 2030. As the main road planning organization in Norway, NPRA set the conditions and manage the procurement process for new roads and ensure that they meet the current standards. Norwegian investment in road infrastructure is set to increase above current record levels therefore NPRA has an important role to play in deciding which roads will be built and who will build them. NPRA will be able to use this influence to help road builders reduce environmental impacts in the roads they construct through their newly launched “Demands for Climate Emissions in Contracts” (KRAKK) project.
In Norway, roads are built per national handbooks that detail the guidelines and construction norms to be used by the road builders. The national handbooks are organized in a coding system where each code describes the process or material used in road construction presented in either physical quantities or monetary values. NPRA designs and chooses the routes for roads and then release a tender for these projects in which different contractors can bid following the process code system. This system is well organized and has the potential to be adapted into a streamlined LCA framework. This framework will be able to give detailed emissions information for NPRA in the bid process and will be easy to implement for road builders, who have knowledge of the process code system.
The current tool that NPRA uses for analyzing emissions road projects, called RoadLCA, is based on process codes and utilizes relatively basic calculation parameters among 5 impact categories. If RoadLCA is to be used on a broader scale for the tender process, it must be updated and expanded with more emissions information that are relevant to Norwegian conditions. This can be done with use of both EPDs and full-scale LCA test studies to improve the accuracy of the results. Process codes that are described in monetary values are currently underrepresented in the RoadLCA model, which may also require implementing hybrid-LCA techniques if more detailed information is not available. The RoadLCA model will also need to be improved to make it easier for road builders to use, and should be designed to avoid any manipulation by road builders who use the model under the competitive tender process.
This paper will present the RoadLCA model and will discuss the technical solutions used to improve the model for broader use in the procurement process. This paper will do this by testing case studies and analyzing them with the RoadLCA model and traditional LCA techniques. This paper will also discuss the challenges of developing such models with use of EPDs and by constructing LCA inventories.

In response to increasing environmental pressure due to climate change, the global community and the Norwegian government have agreed to reduce emissions of greenhouse gases. The government-run Norwegian Public Roads Administration (NPRA) have been tasked with finding ways to drastically reduce their carbon dioxide emissions from road construction and maintenance by the year 2030. In response, NPRA has invested in research and begun the process of developing policy to promote the uptake of cleaner technologies, fuels, materials and processes. This thesis will discuss the solutions and strategies that NPRA can follow to reduce their emissions by presenting a series of articles that focus on the use of life cycle assessment models to calculate emissions of road infrastructure in the early planning phases and by discussing the implementation of emissions reductions policies. The results of this study have shown the use of models can be helpful for calculating emissions but that these models must be sufficiently robust and simple to use in order to be useful during road planning.
