Masonry dry wall constructions in the Swedish Transport Administration – a sustainable building technique
Short description
This pilot study is funded by the Swedish Transport Administration and will demonstrate the current state of knowledge on interventions in masonry dry wall constructions. The work involves identifying actors with both theoretical and practical experience of dry wall construction, followed by an assessment of the potential for developing this area of expertise. The results will form the basis for further research.
Background
In the Swedish infrastructural transportation system on railways and roads, there are thousands of constructions made of stone, such as bridges, drums, walls and retaining walls. Many of these structures have been reinforced or rebuilt over the years, which means that they are changing in terms of construction and strength. However, many objects are still in their original condition and as traditional drystone masonry constructions, built without mortar or concrete.
The knowledge is, however, limited regarding how to calculate the strength of these objects and how to carefully maintain them, whilst simultaneously meeting today's traffic safety and load requirements. There is currently no consolidated overview of existing interdisciplinary research, particularly in relation to bridges, drums, walls, and retaining walls.
Research on masonry dry wall constructions, regardless of type, age or function, has largely focused on buildings and structures other than those mentioned above. There is a substantial body of research on masonry structures, including churches, particularly load-bearing elements in Gothic and Romanesque architecture. However, relatively little has been published on bridge and wall constructions.
Aim and objectives
The aims of the pilot study are twofold. Firstly, it will demonstrate the possibilities for maintenance and care where the original static function of the constructions remains unchanged, as well as the historical, technical, and cultural values. Secondly, it will show the environmental benefits that can be achieved through proper maintenance, thereby reducing emissions from the construction, operation, and maintenance of infrastructure.
The pilot study will conclude in a final report that will be presented at a seminar in October 2026.
