Patent number: 8297874Abstract: A traffic bearing structure with a permeable pavement includes a subgrade, a base positioned on top of the subgrade, and a wear surface positioned on top of the base. The base includes aggregate compacted in a single lift, where the aggregate in the base includes different sized particles mixed together. The wear surface includes a permeable pavement. The particle size distribution of the aggregate in the base is selected to provide adequate stability and permeability for the permeable pavement.Type: GrantFiled: February 26, 2010Date of Patent: October 30, 2012Assignee: Vulcan Materials CompanyInventor: Gerald Krzyzak

Patent number: 8297003Abstract: A gliding bed for a concrete slab comprises a first film and a second film wherein the first film can be brought into contact with a foundation of the concrete bottom slab and the second film can be brought into contact with a bottom side of the concrete slab by pouring concrete onto the second film and which films are tightly connected to each other at edges. In order to minimize friction between the concrete slab and the foundation, at least one gas- and liquid-permeable layer formed from a fleece and/or a textile fabric, a woven fabric or a knitted fabric is provided between the films.Type: GrantFiled: December 20, 2007Date of Patent: October 30, 2012Assignee: VSL International AGInventors: Johann Kollegger, Anton Schweighofer

Publication number: 20120263529Abstract: A process for hardening and rendering a roadbed water resistant by measuring and ensuring the clay content of the roadbed soil is a minimum of 12%, amending the soil to bring the clay content within this range. Treating the top six inches of the roadbed soil with an enzyme formulation and removing and setting aside the treated roadbed soil. Applying two mixtures of organo-silane solution to soil remaining in the roadbed in two separate steps, allowing the treated soil to cure between applications. Adding the enzyme treated soil back onto the roadbed, compacting and crowning the soil, then spraying the surface of the treated roadbed and its associated shoulders with the organo-silane mixture. Once again, the organo-silane mixture is applied in a two step process with two different dilutions of the organo-silane formulation to form a hardened and water resistant envelope of soil within the roadbed.Type: ApplicationFiled: April 12, 2011Publication date: October 18, 2012Inventors: John S. Quackenboss, Earl F. Lockwood, Thomas R. Lujan, Dennis K. Stone, James P. Sweeney
