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 on the hydraulic behavior of stormwater runoff from pavement surfaces. A diffusion wave numerical model was developed to simulate stormwater runoff at superelevation transitions. The model was applied to evaluate the influence of longitudinal grade on maximum ponding depth. Conclusions from the modeling program are that maximum ponding depth does not depend significantly on longitudinal grade, but the location of maximum ponding depth is very sensitive to longitudinal grade, moving from the outside pavement edge for small longitudinal slope, to the center of the roadway for moderate slope, and to the inside pavement edge for large longitudinal grade.
