Permeable joint for paver and structural system therefor
First Claim
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 substantially only 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;
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.

Abstract
A structural system 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.

9. 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 substantially only 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, placing the membrane layer into the joint voids and on top of the base layer, and depositing the membrane layer to have 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. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17)

18. 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 substantially only 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, wherein the membrane member 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. - View Dependent Claims (19)
