Abstract

A method of making a membrane assembly by forming at least a pair of bottom sheet membranes and at least one top sheet membrane, wherein the bottom sheet membranes are adapted to attach to and cover respective pavement sections of a roadway, and constructing each top sheet membrane with a track, wherein each track receives edges of a corresponding pair of the bottom sheet membranes.

Claims (12)

1. A method of making a membrane assembly for embedding in road surfacing material, comprising:

forming at least a pair of bottom sheet membranes and at least one top sheet membrane as respective plates having interlaced high strength fibers consolidated in a polymeric matrix, wherein the polymeric matrix has a melting temperature higher than a temperature of hot asphalt mix, and wherein the bottom sheet membranes are adapted to attach and cover respective pavement sections of a roadway, and wherein the top sheet membrane is adapted to support a road surfacing material thereon; and

constructing each top sheet membrane with a track, wherein each track receives edges of a corresponding pair of the bottom sheet membranes.

2. The method of claim 1 , further comprising:

forming a roughened surface on each top sheet membrane, wherein the roughened surface supports the road surfacing material.

3. The method of claim 1 , further comprising:

forming a smooth bottom surface on each top sheet membrane, wherein the smooth bottom surface slidably engages a corresponding pair of the bottom sheet membranes.

4. The method of claim 1 , further comprising:

adding one or more additional top sheet membranes to the membrane assembly.

5. The method of claim 1 , further comprising:

adding one or more additional bottom sheet membranes to the membrane assembly; and

adding one or more additional top sheet membranes to the membrane assembly, wherein each additional top sheet membrane has at least one track receiving a corresponding edge of an additional bottom sheet membrane.
