About Highway Engineering I
Functional classification systems of highways Highway route selection: factors to be considered in highway route selection, steps in highway route surveys. Geometric design of highways: Design controls and criteria; Highway cross-section elements – lane and shoulders, sidewalks, medians, and pedestrian crossings; Elements of geometric design – sight distance, horizontal alignment: design of circular and transition curves; vertical alignment: grade selection and design of vertical curves; combinations of horizontal and vertical alignment; Intersections and interchanges. Drainage and drainage structures: surface and subsurface drainage facilities. Earthwork quantities and mass-haul diagram
