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 in-depth 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.
