RAILROAD-HIGHWAY GRADE-CROSSING ANALYSIS AND DESIGN. Academic Article

abstract

• This paper presents a computerized design system for a highway-railroad grade-crossing foundation. The design criterion used is the permanent differential deformation between the railroad track and the adjacent highway pavement. This design criterion is related to two performance criteria: dynamic-load profile and roughness index. The effect of the permanent differential deformation on increasing highway dynamic load is included in the computer program, as is the increase in dynamic railroad wheel loads. Characteristic properties of materials, including the effects of environmental factors (such as temperature and suction), on subgrade material properties are considered.
