A control arrangement co-ordinates movement of the impact point of the jet member and said indexing for treating a surface of said layer having said geometrical shape by said jet member.Type: GrantFiled: October 27, 2008Date of Patent: September 3, 2013Assignee: Aquajet Systems Holding ABInventor: Ronnie Hilmersson

Publication number: 20130223929Abstract: The apparatus and method comprise a concrete float with a vibratory additive broadcaster assembly attached therewith. The broadcaster assembly is suspended above the plane of the finishing tool with a vibratory source attached. The broadcaster assembly is filled with an additive and the apparatus is placed on a wet, concrete surface that is to be treated and finished, by a user. Actuation of a power switch by the user activates the vibratory source resulting in the substantial broadcast of additive on to the concrete surface at the desired location(s) on the slab as determined by the user. Vibration damper devices are utilized to minimize the vibrations experienced by the float. The additive is integrated into the concrete or other wet surface by passage of the float over the surface being treated.Type: ApplicationFiled: May 1, 2012Publication date: August 29, 2013Inventor: John Scott Stephens

Publication number: 20130223930Abstract: A method for compacting a surface of granular materials is disclosed. The method is applicable to wheeled compaction equipment such as pneumatic-tire compactors, drum-type compactors and asphalt compactors. The propel system includes a controller programmed to send a first at least substantially constant propel command that propels the compaction equipment in a forward direction. The controller then changes the speed of the compaction equipment by providing a second varying propel command that may increase or decrease the speed resulting from the first command. As a result, the speed of the compaction equipment oscillates, and the compaction process is improved.Type: ApplicationFiled: April 5, 2013Publication date: August 29, 2013Applicant: CATERPILLAR INC.Inventor: CATERPILLAR INC.

Publication number: 20130216308Abstract: Provided herein are roadways containing polyurethane materials. A roadway includes a base layer of a compacted in situ material and/or a wear layer disposed on the base layer. One or both of these layers may include the polyurethane material to bind other components in the layers and to form more robust and durable roadway structures capable of withstanding operating loads of the roadway. In some embodiments, the polyurethane material is added to the wear layer by mixing in situ soil and/or foreign aggregate with polyurethane material or by dispensing the polyurethane material over the existing partially formed wear layer. The base layer may or may not include a polyurethane material. The type, concentration, distribution, and processing of the polyurethane material in the wear layer may be the same or different than that in the base layer.Type: ApplicationFiled: April 3, 2013Publication date: August 22, 2013Inventor: Sean Somers Weaver

Publication number: 20130216307Abstract: A method of forming a roadway is provided comprising providing a reclaimer-stabilizer machine, providing in-situ soil materials, forming a base layer using the reclaimer-stabilizer machine, forming a wear layer over the base layer, and wherein the wear layer comprises a polyurethane composition in addition to the in-situ materials. In some embodiments the roadway is comprised of a single layer comprising a polyurethane material. In other embodiments a method of forming a roadway comprising cured asphalt composite is provided.Type: ApplicationFiled: February 20, 2013Publication date: August 22, 2013Inventor: Sean Somers Weaver
