Bearing Capacity of Roads, Railways and Airfields focuses on issues pertaining to the bearing capacity of highway and airfield pavements and railroad track structures and provided a forum to promote efficient design, construction and maintenance of the transportation infrastructure. The collection of papers from the Eighth International Conference on the Bearing Capacity of Roads, Railways and Airfields (BCR2A09) includes contributions on a variety of topics and will be of particular interest to academics, researchers, and practitioners involved in geotechnical, pavement, and railroad engineering disciplines. It is primarily concerned with the many issues pertaining to the bearing capacity and mechanistic based design of highway and airfield pavements and railroad track structures.
