Surface drainage system
First Claim
1. A surface drainage structure formed above a subgrade, comprising:
- an elongate drain pipe defining a longitudinal axis, the pipe having a plurality of elongate drain slots wherein a lengthwise direction of the elongate drain slots is parallel to the longitudinal axis and extends through a wall of the pipe; and
a pavement layer with an exposed top surface and the elongate drain pipe being at least partially disposed in the pavement layer, the pavement layer defining a drainage channel extending from the top surface and being in fluid communication with the plurality of elongate drain slots of the elongate cylindrical drain pipe, wherein the drainage channel is defined by opposed side surfaces and a channel surface, the channel surface having a flat segment extending in a parallel relation to the top surface, and opposed inclined segments connecting the flat segment to a wall of the elongate drain pipe.

Abstract
A surface drainage structure formed above a subgrade may include an elongate drain conduit disposed partially within the subgrade. The elongate drain conduit may define at least one drain slot extending through a wall thereof. The structure may include a pavement layer with an exposed top surface and a drainage channel extending therefrom. The drainage channel may be in fluid communication with the drain slot of the elongate drain conduit. A method of forming the surface drainage structure includes placing the elongate drain conduit in the subgrade, forming the pavement layer, cutting an upper channel along the elongate drain conduit, and cutting a lower channel and the drain slot in the elongate conduit.
