Highway Drainage at Superelevation Transitions

摘要: This research has addressed issues associated with highway drainage at superelevation transitions. A physical modeling experimental program focused on the effects of surface roughness and rainfall intensity hydraulic behavior stormwater runoff from pavement surfaces. diffusion wave numerical model was developed to simulate The applied evaluate influence longitudinal grade maximum ponding depth. Conclusions are that depth does not depend significantly grade, but location is very sensitive moving outside edge for small slope, center roadway moderate inside large grade.
