Patent number: 6187428Abstract: A wheel rut-resistant carriageway and process for obtaining a wheel rut-resistant carriageway. The wheel rut-resistant carriageway includes at least one rigid base layer, at least one intermediate layer, and a rough upper layer. The at least one rigid base layer has a thickness in the range of approximately 6 cm to approximately 8 cm. The at least one intermediate layer is disposed over the at least one rigid base layer and has a thickness in the range of approximately 4 cm to approximately 5 cm. The at least one intermediate layer has a high void rate allowing for the evacuation of heat by ventilation. The rough upper layer is disposed over the intermediate layer and has a thickness in the range of approximately 2 cm to approximately 3 cm. The process includes applying the at least one rigid base layer having a thickness in the range of approximately 6 cm to approximately 8 cm to a surface.Type: GrantFiled: December 29, 1998Date of Patent: February 13, 2001Assignee: Colas S.A.Inventor: Alain Chambon

Patent number: 5893679Abstract: A process and a machine for forming a bonding layer for bonding a bituminous coated material layer on a support. The process includes application of a surface-active agent on the support, application of a bituminous emulsion on the surface-active agent on the support, and application of a breaking agent on the bituminous emulsion to form the bonding layer. A road-type coating made by the process and, therefore, including such a support layer, a bonding layer on the support, and a bituminous coated materials layer on the bonding layer. To perform the process, a machine includes a frame, a displacement mechanism on the frame, a bituminous-emulsion spreader on the frame, a surface-active agent applicator on the frame, and a breaking agent applicator on the frame.Type: GrantFiled: January 12, 1998Date of Patent: April 13, 1999Assignee: Colas S.A.Inventors: Graziella Durand, Pierre Montmory

Patent number: 5324136Abstract: The apparatus for spreading a fluid or similar substance, especially a bonding emulsion for road asphalt onto the surface of a road, comprising, on a movable vehicle (1), at least one spreading boom (18, 19), along which the spreading is carried out at least partially, said boom being associated with at least one ejection nozzle (23, 24) and with a feed circuit (8; 106) and being capable of being displaced relative to the movable vehicle (1) transversely to the direction of movement of the latter, and is associated with motor means (30) intended for driving it in displacement, during spreading, in a to-and-fro movement. The machine of the finisher type comprises such an apparatus.Type: GrantFiled: April 17, 1991Date of Patent: June 28, 1994Assignee: Colas S.A.Inventors: Jean-Pierre Reymonet, Michel Perrin, Clement Beatrix, Pierre Defontaine

Patent number: 5310118Abstract: Mechanical actuating device for opening or closing a valve of at least one nozzle, the nozzle moving along a path preset with respect to a support. The valve comprises a mobile control unit which is movable between an open position and a closed position, and elements for mechanically moving the control unit including at least one guide rail fitted with a flexure in the area of the open or closed position enabling the control unit to switch from one position to the other.Type: GrantFiled: August 7, 1992Date of Patent: May 10, 1994Assignee: Colas S.A.Inventor: Jean-Pierre Reymonet

Patent number: 5279500Abstract: Apparatus for spreading a fluid or like substance, for example, an emulsion for bonding bituminous coated material on the surface of a road including a mobile machine, at least one spreading bar along which the spreading is at least partially effected, and at least one ejection nozzle associated with the at least one spreading bar. A supply circuit supplying emulsion to the nozzle. The at least one nozzle is associated with a mechanism for controlling delivery of the emulsion and a mechanism for controlling positioning of the nozzle relative to the machine. Both of the mechanisms are operated simultaneously, in dependence on the movement of the mobile machine, in such a manner that the nozzle effects spraying by sequenced jets of the substance to continuously cover the surface which is to be spread. The machine provided with this apparatus is of the finisher type.Type: GrantFiled: August 5, 1991Date of Patent: January 18, 1994Assignee: Colas S.A.Inventors: Michel Perrin, Jean-Pierre Reymonet, Clement Beatrix, Pierre Defontaine, Philippe Brissonneau, Jean-Pierre Gravet

Patent number: 5190399Abstract: Vehicle including, mounted on a chassis, a device for receiving material to be spread, a device for transferring the material towards a spreading component, a tank for binding product, a distribution bar, and a motorization assembly. The chassis includes at a rear portion, after the component for spreading the material, and mounted on rollers or balls that are rotatable independent of rolling elements mounted on a front portion, at least one of the motorization assembly, the tank and a control and transmission mechanism providing weight to the rear portion to permit the rear portion to act as a compactor.Type: GrantFiled: September 6, 1991Date of Patent: March 2, 1993Assignee: Colas S.A.Inventors: Michel Chappat, Jean-Pierre Reymonet
