Abstract

A mesh assembly for the formation of pervious pavement is disclosed. The mesh is defined by a plurality of elongated structural members. The mesh has a first side and a second side. A plurality of conduits are coupled to and extend through the mesh. Each conduit has a first end defining a first opening, a second end defining a second opening, and a passageway extending between the first opening and the second opening. The plurality of conduits each have at least one of the elongated structural members extending through a sidewall of the conduit such that the first opening is positioned on the first side of the mesh and the second opening is positioned on the second side of the mesh.

Claims

1. A mesh assembly for the formation of pervious pavement, the mesh assembly comprising:

a plurality of wires coupled together to form a mesh having a first side and a second side, the plurality of wires defining wire intersections; and

,

a plurality of conduits coupled to and formed separately from the mesh, each conduit including a first end defining a first opening on the first side of the mesh, and a second end defining a second opening on the second side of the mesh, each conduit surrounding one of the wire intersections such that the wire intersection is located within the conduit and is spaced a distance from each of the first end and the second end, wherein the second openings are adapted to be engageable with a subgrade surface, and wherein the plurality of conduits include sufficient rigidity to support and space the mesh above the subgrade surface.

2. The mesh assembly of claim 1, wherein each conduit extends substantially perpendicular to the mesh.

3. The mesh assembly of claim 1, further comprising a plurality of caps, each cap received by the first opening of a respective one of the plurality of conduits.

4. The mesh assembly of claim 3, wherein each cap includes a ferromagnetic insert for removing the cap from the first opening of the respective one of the plurality of conduits using a magnetic force.

5. The mesh assembly of claim 1, wherein at least some of the plurality of conduits define a longitudinal axis and include radially outwardly extending support walls.

6. The mesh assembly of claim 1, wherein the wire intersection located within each conduit divides the conduit into an upper portion and a lower portion and defines a support structure for supporting drainage material that is receivable within the upper portion.

7. The mesh assembly of claim 1, wherein each wire intersection is located a greater distance from the second end than from the first end of its respective conduit.

8. The mesh assembly of claim 1, wherein each conduit includes a sidewall defining openings, and wherein the plurality of wires extend through the openings in the sidewalls.

9. The mesh assembly of claim 8, wherein the plurality of wires are formed from a first material, and wherein the plurality of conduits are formed from a second material different from the first material.

10. Pervious pavement comprising:

a subgrade surface formed of subgrade material;

a mesh assembly supported by the subgrade material, the mesh assembly including a plurality of elongated structural members coupled together to form a mesh and defining intersections, the mesh assembly also including a plurality of conduits extending through and supporting the mesh a distance above the subgrade surface, each conduit having a first end defining a first opening on a first side of the mesh, and a second end defining a second opening on a second side of the mesh, the second end engaging the subgrade material, each conduit surrounding one of the intersections such that the intersection is located within the conduit and divides the conduit into an upper portion and a lower portion; and

,

substantially non-pervious paving material located in spaces between the plurality of conduits and extending between the subgrade surface and the first ends of the conduits, wherein the conduits provide an open flow path between a top surface of the non-pervious paving material and the subgrade material.

11. The pervious pavement of claim 10, wherein the second end of each conduit engages the subgrade surface.

12. The pervious pavement of claim 10, further comprising subbase material located in the spaces between the plurality of conduits and extending between the subgrade surface and the paving material.

13. The pervious pavement of claim 10, wherein each conduit extends substantially perpendicular to the mesh.

14. The pervious pavement of claim 10, wherein each intersection is located a greater distance from the second end than from the first end of its respective conduit.

15. The pervious pavement of claim 10, wherein each conduit includes a sidewall defining openings, and wherein the elongated structural members extend through the openings in the sidewalls.

16. The pervious pavement of claim 10, wherein the elongated structural members include wires formed from a first material, and wherein the plurality of conduits are formed from a second material different from the first material.

17. The pervious pavement of claim 10, further comprising previous drainage material located in the upper portion of each conduit and supported above the lower portion of each conduit by a respective one of the intersections.

18. A method of making pervious pavement, the method comprising:

preparing a subgrade surface formed of a subgrade material;

positioning a mesh assembly on the subgrade material, the mesh assembly including a plurality of elongated structural members coupled together to form a mesh and defining intersections, the mesh assembly also including a plurality of conduits extending through the mesh, each conduit having a first end defining a first opening on a first side of the mesh, and a second end defining a second opening on a second side of the mesh, each conduit surrounding one of the intersections such that the intersection is located within the conduit and divides the conduit into an upper portion and a lower portion, wherein positioning the mesh assembly on the subgrade material includes positioning the second end on the subgrade material such that the mesh is supported a distance above the subgrade surface; and

,

pouring a substantially non-pervious paving material into spaces between the plurality of conduits until a top surface of the paving material is substantially even with the first ends of the conduits, wherein the conduits provide an open flow path between a top surface of the non-pervious paving material and the subgrade material.

19. The method of claim 18, further comprising introducing a pervious drainage material into the upper portion of each conduit, wherein the drainage material is supported above the lower portion of each conduit by a respective one of the intersections.

20. The method of claim 18, wherein the conduits include sidewalls having openings formed therein, the method further comprising forming the mesh assembly by inserting the elongated structural members through the openings in the sidewalls.

21. The method of claim 18, wherein the conduits each include a cap received by the first opening, the method further comprising removing the caps from the first openings after pouring the substantially non-pervious paving material and before introducing the pervious drainage material.

22. The method of claim 18, wherein each cap includes a ferromagnetic member, and wherein removing the caps from the first openings includes passing a magnet over the caps.
