Abstract

A structural system is provided that includes at least two pavers partially defining a paved surface, the pavers partially defining a void between them. The system also includes a permeable joint located in the void between the pavers, where the permeable joint also partially defines the paved surface. The permeable joint includes a base layer formed of aggregate and bonded together with a non-cement binder, and a membrane layer formed of aggregate that is sized smaller than the aggregate of the base layer, where the aggregate of the membrane is also bonded together with a non-cement binder. The membrane is less permeable than the base layer and is located above the base layer.

Claims

1. A paver structural system having a permeable joint, the system comprising:

at least two pavers partially defining a paved surface of the paver structural system, the at least two pavers partially defining a void therebetween;

a permeable joint located in the void between the at least two pavers, wherein the permeable joint also partially defines the paved surface, the permeable joint comprising;

a base layer formed of aggregate and bonded together with a non-cement binder; and

a membrane layer formed of aggregate that is sized smaller than the aggregate of the base layer, wherein the aggregate of the membrane is also bonded together with a non-cement binder, wherein the membrane layer is less permeable than the base layer, and wherein the membrane layer is located above the base layer.

2. The paving system of claim 1, wherein the non-cement binder of the base layer is the same non-cement binder of the membrane layer.

3. The paving system of claim 1, wherein the aggregate size of the base layer is in the range of #4 to #20 ASTM.

4. The paving system of claim 1, wherein the aggregate size of the membrane layer is in the range of #20 to #50 ASTM

5. The paving system of claim 1, wherein the membrane layer is disposed in the void between the at least two pavers and is not disposed on a top surface of the at least two pavers.

6. The paving system of claim 1, wherein the base layer has a compressive strength in the range of 2300 to 2800 psi for a 7-day cure.

7. The paving system of claim 1, wherein the system has a permeability in the range of 0.45 to 6.0 gal/sqft/min.

8. The paving system of claim 7, wherein the system has a permeability in the range of 0.50 to 1.0 gal/sqft/min.

9. The paving system of claim 1, wherein the membrane layer has a thickness in the range greater-than 0 to ¼

-inch to fill the void between the base layer and a top surface defined by the at least two pavers.

10. A method of placing the paver structural system having a permeable joint, the system comprising:

laying at least two pavers on a substrate layer;

spacing the at least two pavers from each other in a spaced arrangement forming joint voids therebetween;

forming a first slurry containing aggregate, water and a non-cement binder to form the base layer;

applying the base layer of the permeable joint over the paver structural system, and placing the base layer into the joint voids;

curing the base layer for at least 30-minutes;

forming a second slurry containing aggregate, water and a non-cement binder to form the membrane layer, wherein the aggregate of the second slurry is smaller than the aggregate of the first slurry; and

applying the membrane layer of the permeable joint over the paver structural system, and placing the membrane layer into the joint voids and on top of the base layer.

11. The method of claim 10, wherein the spacers are preferably spaced from about ⅜

-inch to ⅝

-inch apart from each other.

12. The method of claim 10, wherein the pavers are placed into the substrate layer from about ¼

-inch to ⅜

-inch depth.

13. The method of claim 10, wherein the base layer is squeegeed into the joint voids.

14. The method of claim 10, wherein the base layer fills the joint void up in the range of about ¼

-inch below a top surface of the pavers to 1/32-inch from the top surface of the pavers.

15. The method of claim 10, wherein the membrane layer is squeegeed into the joint voids.

16. The method of claim 10, wherein the non-cement binder of the base layer is a two-part permeable epoxy binder having a foaming agent.

17. The method of claim 10, wherein the non-cement binder of the membrane layer is a two-part permeable epoxy binder having a foaming agent.

18. The method of claim 17, wherein the non-cement binder of the membrane layer is the same non-cement binder of the base layer.

19. A permeable joint for a paver structural system having individual pavers that form a paved surface, the permeable joint comprising:

a base layer comprising aggregate sized in the range of #4 to #20 ASTM and a two-part permeable epoxy binder having a foaming agent; and

a membrane layer comprising aggregate sized in the range of #20 to #50 ASTM and the two-part permeable epoxy binder having the foaming agent;

wherein the base layer is mixed into a slurry with water and deposited between the individual pavers; and

wherein the membrane layer is mixed into a second slurry with water and deposited between the individual pavers and above the base layer.

20. The permeable joint of claim 19, wherein the permeable joint has a permeability in the range of 0.45 to 6.0 gal/sqft/min where the permeable joint constitute in the range of 10% to 15% of the paved surface.
