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. 1. A bitumen-impregnated material comprising:from about 10% to about 40% by weight bituminous material, cellulose fibers,one or more filler materials,a sufficient amount of at least one dye to color the cellulose fibers and/or filler materials, andoptionally, an outer coating disposed on both major sides of the bitumen-impregnated material.2.

Some natural asphalts deposits, like those in Trinidad, Venezuela and Iraq, are thermoplastic in nature. After removing the water content, the resulting refined asphalt flows, coalesces, and its mineral matter sediments when blended with refinery bitumen. Packaged in 250 kg coated kegs and barrels, specialized road-paving plants are required for use. On the other hand, gilsonites, also a natural asphalts, are used-friendly, but performs unsatisfactorily compared with refined asphalts as a modifier of refinery bitumen for road-paving. Furthermore, refinery bitumen has been polymerized with polymers for decades. This polymerization of bitumen is used in this patent—the bitumen in these natural asphalts are polymerized with polymers to produce PMNAs which are user-friendly (discrete elements do not flow or coalesce), could be packaged in powders or pellets, could be used with conventional road-paving equipment so there is no need for specialized equipment, and saving costs to the end-user. 16-.

SEQUESTERING POLYCYCLIC AROMATIC HYDROCARBONS IN ASPHALT

Номер: US20150020711A1
Принадлежит: FLOW POLYMERS LLC

This invention is based upon the discovery that activated carbon can be used to sequester polycyclic aromatic hydrocarbons that may be present in asphalt and creosote compositions. The treatment of asphalt and creosote compositions with activated carbon accordingly reduces the level of free polycyclic aromatic hydrocarbons in such compositions by sequestering them therein or removing them from the composition. After being sequestered the polycyclic aromatic hydrocarbons remain trapped in the asphalt or creosote composition, and are not available to the environment during normal processing into useful industrial products. This sequestration reduces the risk of exposing humans and the environment to the polycyclic aromatic hydrocarbons which would otherwise be free to migrate from the asphalt or creosote product during manufacturing and the service life of the product. In other words, the polycyclic aromatic hydrocarbons are absorbed onto the activated carbon and are not available for bioaccumulation from the environment. 1. An asphalt composition having a low level of free polycylic aromatic hydrocarbons which is comprised of an asphalt and activated carbon having polycylic aromatic hydrocarbons sequestered thereon.2.
