The method comprises the steps of applying a binding material to the surface, applying an aggregate mixture within 15 seconds of applying the binding material to the surface, and allowing the binding material to fill some of the air voids in the aggregate mixture to form a substantially voidless layer with a height of at least 0.38 cm.Type: ApplicationFiled: February 22, 2011Publication date: June 16, 2011Applicant: ROAD SCIENCE, LLCInventors: Marvin Keller Exline, Jon Brett Wingo, James Joseph Cunningham, JR., James J.

Patent number: 7918624Abstract: A method for bonding together an existing substrate layer and a pavement layer, such that a strong adhesive bond is formed by using a tack coat, provided by an asphalt emulsion, in between the layers as the bond coat. The tack coat layer is a low-tracking coating which cures quickly such that the pavement layer may be applied to the substrate, hours to days after the emulsion is applied to the substrate. The asphalt emulsion comprises at least a first phase of from about 30% to about 70% of an asphalt composition, about 30% to about 70% water, and about 0.1% to about 3.0% emulsifying agent, stabilizer and/or additives, or 0.1% to about 30% if polymeric or other additives are also included.Type: GrantFiled: March 12, 2009Date of Patent: April 5, 2011Assignee: Blacklidge Emulsions, Inc.Inventor: Roy B.

Publication number: 20110064517Abstract: A pavement such as a road, driveway, sidewalk, parking lot or the like, formed with pervious concrete material and one or more basalt reinforcing members embedded in or positioned below the pervious concrete material. The one or more basalt reinforcing members add structural rigidity to the pervious concrete, making the pervious concrete capable or supporting loads as normally experienced on pavements. The one or more basalt reinforcing members may be basalt rebar rods, or basalt rebar rods having a Figure-Eight shape, or a mesh made of basalt strands. In one example, the pavement may also include a layer of filtration fabric positioned below the basalt reinforcing members. Various methods are described for forming pavements, roads, driveways, sidewalks, parking lots or the like. Such a pavement allows water or moisture to pass through the surface of the pavement and be filtered. Such a pavement reduces flooding and the need for complex storm drainage systems adjacent to the pavement.Type: ApplicationFiled: March 25, 2010Publication date: March 17, 2011Inventor: Jon Dennis Sader

Publication number: 20110038668Abstract: The present invention relates to a method for applying a crack resistant coating on a surface, where the crack resistant coating increases resistance to high vertical and horizontal movements and high shear stresses on the surface. The method comprises the steps of applying a binding material to the surface and applying an aggregate mixture within 15 seconds of applying the binding material to the surface, where the aggregate mixture comprises aggregate particles and an asphalt solution and where the aggregate mixture has a plurality of air voids, and where the binding material fills at least 15% of the air voids in the aggregate mixture (AVFA).Type: ApplicationFiled: August 13, 2009Publication date: February 17, 2011Applicant: Road Science, LLC.Inventors: Marvin Keller Exline, Jon Brett Wingo, James Joseph Cunningham, JR., James J.

Publication number: 20100284740Abstract: A paving system for paving or flooring includes a top layer of a plurality of paving elements, and an underlayment support layer of a polymeric material configured into panels. The panels are suitable to support the paving elements, the panels having a generally planar support surface and a recovery characteristic such that a deformation from a concentrated compressive load applied for a short duration returns the support surface to a generally planar condition.Type: ApplicationFiled: July 6, 2010Publication date: November 11, 2010Applicant: BROCK USA, LLCInventors: Daniel C. Sawyer, Richard R. Runkles

Patent number: 7802941Abstract: The present invention is directed to a rut resistant coating and a method for applying the rut resistant coating on an existing surface for increasing resistance to high vertical and horizontal strains and high shear stresses. The method includes applying a binding material layer of the rut resistant coating on the existing surface to provide a substantially impermeable moisture barrier to the existing surface, the binding material layer containing less than about 11% of the total binding material of the rut resistant coating. After applying the binding material layer, an aggregate mixture layer is applied on the binding material layer to provide the wear surface of the rut resistant coating and support and structure to the rut resistant coating to resist rutting, the aggregate mixture layer containing an asphalt solution.Type: GrantFiled: April 28, 2008Date of Patent: September 28, 2010Assignee: Road Science, L.L.C.Inventors: Jon Brett Wingo, Marvin Keller Exline, James Joseph Cunningham, Jr.

Patent number: 7798744Abstract: This invention relates to a novel seal coat process and equipment for applying the seal coat to improve the reliability of seal coat aggregate retention to the surface of the pavement by increasing the surface area of aggregate covered with binder and interlocking the aggregate with finer gradation material such as choke stone. It also relates to the use of lower amounts of asphalt binder, lower amounts of aggregate application, lower quality of aggregates, use of softer binders, and faster release to traffic times.Type: GrantFiled: October 15, 2007Date of Patent: September 21, 2010Assignee: Road Science, L.L.C.Inventors: Larry Larson, John Domichel
