Abstract: This research develops a model to solve for the three-dimensional alignment of a highway segment. Code requirements are taken into consideration, and mechanisms for maintaining heavy vehicle speeds are embedded in the ...

Abstract: In practice, the task of designing the vertical alignment of a highway is done manually by an experienced engineer. As a result, the work is both time and resource consuming and relies heavily on human expertise. This work ...

Abstract: This research presents an optimization heuristic to solve the horizontal alignment of a highway segment. The iterative heuristic works in two stages. The first stage uses a neighborhood search approach to find a good ...

Abstract: In this article, the influence of gluing-solution layout on the gluing-solution distribution at the final stage of solidification process in a realistic railway ballast is investigated. A unified Cauchy stress model, with ...
