- an elongate drain conduit disposed partially within the subgrade, the elongate drain conduit defining a plurality of drain slots extending through a wall thereof, the plurality of drain slots further extending along a common axis; and
a pavement layer with an exposed top surface, the pavement layer defining a drainage channel extending from the top surface and being in fluid communication with the plurality of drain slots of the elongate drain conduit, the drainage channel being 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 an inclined segment connecting the flat segment to the wall of the elongate drain conduit.

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.
