BCRRA Conference Background and History
BCRRA 26 will be the 12th conference in a series held at four-year intervals, which began in Trondheim, Norway, in 1982. Originally established as the “Bearing Capacity of Roads and Airfields (BCRA),” the conference initially focused on the design, construction, and maintenance challenges associated with roads and airfield pavements. In 1997, during the sixth conference held in Lisbon, Portugal, the scope of BCRA was expanded to include railway tracks, recognizing the vital role of railway infrastructure in global transportation networks. This expansion led to the conference being rebranded as BCRRA, reflecting its comprehensive focus on roads, railways, and airfields.
BCRRA is known for its rigorous academic discussions, technical presentations, and the dissemination of research that has often led to the development of new standards and best practices. Topics typically covered include advancements in materials science, pavement design, geotechnical engineering, environmental considerations, and the integration of new technologies. As bearing capacity issues evolve due to increasing traffic volumes and weights, there is a growing need for stronger and more durable pavements and railroad track structures. New materials and methods are being introduced, along with innovative approaches to design and material utilization.
BCRRA attracts a diverse international audience, including researchers, engineers, consultants, and representatives from government agencies and international organizations. The conference’s collaborative environment fosters cross-border partnerships and the global sharing of knowledge, further enhancing its influence on infrastructure development worldwide.
The 12th BCRRA conference in 2026 will introduce new concepts and innovative solutions in several areas, including subgrade soils, granular materials, asphalt mixtures, concrete materials, recycled materials and technologies, in situ measurements, results evaluation, performance prediction, climate change resilience, frost-affected design, geotechnical considerations, intelligent construction technologies, and the application of big data and AI.

Venue
Cankarjev dom is the largest cultural and congress centre in Slovenia, located in the heart of Ljubljana. It is a prominent venue for a wide range of cultural, artistic, and professional events, including concerts, theatre performances, film screenings, exhibitions, conferences, and congresses.
Designed by architect Edvard Ravnikar, Cankarjev dom is an architectural landmark in Ljubljana, reflecting modernist design principles. The building, completed in 1982, is known for its functional design and use of space, making it one of the most iconic cultural venues in Slovenia.
Cankarjev dom hosts over 1,200 events annually, attracting around half a million visitors. It is the main venue for cultural events in Ljubljana, including music festivals, film festivals (such as the Ljubljana International Film Festival), and theatre performances. With its state-of-the-art facilities, Cankarjev dom is a leading venue for international congresses and conferences in Slovenia.
Cankarjev dom is part of various international networks, collaborating with global cultural and congress organizations. This enhances its reputation as a prime location for both cultural exchange and international business events.
An administrative centre of Ljubljana, where Cankarjev dom is located, is easily accessible on foot, by car or by public transport. Under the Square of the Republic there is a large parking garage, and the latest one is just a stone’s throw away under the Congress Square. Both are sufficient to cover the needs of conference guests with cars. A great advantage of the location is that all the city’s attractions, and especially the key hotels are within walking distance. In these terms Cankarjev dom is a very friendly and nice location to conference guests.
