Permeable paving material and method of installation

Abstract

A permeable paving structure that includes a stabilizer, a base course layer, and a wearing course layer. The stabilizer is adapted to be engaged with a ground surface in at least two planes. The base course layer operably engages with the stabilizer, and the wearing course layer operably engages with the base course layer and with the stabilizer. The stabilizer is configured to stabilize the base course layer and the wearing course layer in the at least two planes.

 a drainage pipe positioned inside of at least the base course layer.   
     
     
         5 . The permeable paving structure of  claim 3 , wherein the at least one stabilizer is a geomembrane to prevent complete infiltration of the fluid into the subgrade of the ground surface. 
     
     
         6 . The permeable paving structure of  claim 1 , wherein the at least one stabilizer further comprises:
 a first stabilizer adapted to be engaged with a support structure in a first plane of the at least two planes; and   a second stabilizer operably engaged with the base course layer and the wearing course layer in a second plane of the at least two planes that is non-parallel to the first plane;   wherein the second stabilizer is separate from the first stabilizer.

         10 . The permeable paving structure of  claim 9 , wherein the wearing course layer further defines a third thickness that is less than the first thickness and the second thickness. 
     
     
         11 . The permeable paving structure of  claim 1 , wherein the base course layer further comprises:
 a first aggregate having a first plurality of stone, wherein each stone of the first plurality of stone defines a first length; and   a second aggregate having a second plurality of stone, wherein each stone of the second plurality of stone defines a second length that is less than the first length.   
     
     
         12 . The permeable paving structure of  claim 1 , wherein the wearing course layer further comprises:
 a binder for binding an aggregate of the wearing course layer together to form the wearing course layer as a unitary member.   
     
     
         13 . A method of installing a permeable paving structure, comprising:
 compacting a subgrade of a ground surface;   installing at least one stabilizer with the subgrade; wherein the at least one stabilizer provides structural support in at least one plane;   installing a base course layer with the at least one stabilizer and the subgrade;   expanding the at least one stabilizer subsequent to the base course layer being installed with the at least one stabilizer; wherein the at least one stabilizer provides structural support in a second plane; and   installing a wearing course layer with the base course layer and the at least one stabilizer.   
     
     
         14 . The method of  claim 13 , wherein fluid permeates through each of the at least one stabilizer, the base course layer, and the wearing course layer for complete infiltration of fluid in the subgrade of the ground surface. 
     
     
         15 . The method of  claim 13 , further comprising:
 positioning an underdrain system in at least the base course layer and the subgrade of the ground surface;   capturing fluid permeating through the base course layer; and   directing said fluid away from the permeable paving structure and the subgrade.   
     
     
         16 . The method of  claim 15 , wherein the step of positioning the underdrain system further comprises:
 positioning a drainage pipe of the underdrain system inside of at least the base course layer.
