Abstract: A method of manufacturing a wood product including using a water and wax mixture with wood particles in a production process of wood products, wherein the wax mixture includes a hydrocarbon wax, and a water-repellant material selected from the group consisting of (a) an asphaltite, (b) a polyolefin copolymer, (c) a polyolefin synthetic wax, and (d) combinations thereof, and forming a wood product.

Abstract: The present invention relates to emulsions comprising a (1?3)-?-D-glucan, a cationic emulsifier and a bituminous binder having a low penetration. The emulsion is storage stable whilst fast breaking, even under unfavourable environmental conditions such as high humidity and low temperature.

Abstract: Cellulose fibers are treated with a surfactant package to improve their use in the formation of viscosity enhancing gel structures in asphalt compositions. In a particular embodiment, the cellulose fibers are obtained from recycling magazines, newspapers and similar such materials, and are used in asphalt compositions that incorporate the use of other viscosity modifiers, such as mineral aggregates and fillers like attapulgite clay. The use of surfactant-treated cellulose fibers improves the formation, strength and durability of the gel structure and reduces the number of manufacturing steps normally required in the process for producing the asphalt compositions. Use of these fibers can eliminate or reduce the need to maintain and handle stocks of potentially harmful and corrosive liquid surfactants.

Abstract: A process for manufacturing fiberboard by preparing a fiber slurry mixture including containing cellulose fibers and water then atomizing a liquid bituminous material, such as asphalt. The liquid bituminous material is atomized by mixing it with a pressurized gas, such as compressed air, forming a mist comprising droplets of bituminous material having a diameter between 20 microns and 50 microns. A water spray solidifies the bituminous material droplets thereby forming bituminous particles which fall into the fiber slurry within the spray chamber. From there the slurry is sheared, dewatered, and dried, forming a finished fiberboard.

Abstract: The present invention relates to stone mastic asphalt compounds which are produced using a new technique and process. The process utilizes a specific aggregate gradation and matrix for high stability. Specially formulated fiber mastic asphalt is used to hold the aggregate in place while providing extended durability. This formulation is able to handle heavy loading from commercial vehicles and thus minimize pavement surface distresses. The use of the present invention is expected to reduce the cost of materials by about 15 to 20 percent.

Abstract: A method is described for the modification of asphaltic compositions such that cellulosic fibers are not degraded by the asphalt at elevated temperatures. This is achieved by the addition of addition of certain inorganic or organic alkaline materials to the composition. As a further embodiment of the invention, a method is also described for the dispersion of cellulosic fibers in liquid asphalt in such a way as to obtain a thermally stable product with defined viscoelastic properties. This comprises blending the fibers with asphalt, fibers and alkaline additives under controlled mixing conditions such that the required viscometric specification is attained.
