Abstract:

Proper drainage of the roadway is essential to highway safety. Drainage systems for roadways with curb and gutters are designed to limit spread of water on the pavement. Excess water must be captured by curb and gutter inlets. To locate and size these inlets properly, designers need reliable information on their hydraulic performance. This report provides complete information on the hydraulic performance characteristics of KDOT's standard curb and gutter inlets on grade and in sag locations. It also provides design charts for the spread of water on roadways with curbs and gutters. The design charts for inlets on grade were developed from hydraulic model tests. The inlets, curbs and gutters were modeled at one-quarter scale. The model roadway was 15 m long with adjustable grade and cross-slope. The depth-discharge relationships for the inlets in sag locations were computed from fundamental hydraulic principals of orifice flow and weir flow. Relationships for the spread of water on streets with the standard gutter and the Type I combination curb and gutter were also developed from standard hydraulic formulas. The design aids in this report provide a sound basis for the selection and sizing of curb and gutter inlets. References, appendices, tables, figures. 61p.
