524062000 | With hydrocarbon DNRM additive which is nonresinous and which is nonbituminous, or noncoal derived, e.g., cutback asphalt, kerosene, paraffin wax, etc. | 10 |
20080255277 | Roofing Felt Composition - The invention is directed to a novel bitumen composition comprising a paraffin wax, wherein the wax has a congealing point of between 85 and 120° C. and a PEN at 43° C., expressed in 0.1 mm, as determined by IP 376 of more than 5. | 10-16-2008 |
20080281022 | Metallocene-catalyzed polyolefins in wax formulations and their use for the precision casting/lost wax process - The invention relates to a wax formulation comprising

20100292369 | BITUMEN MIXTURE AND USE THEREOF - Bitumen mixtures for high-quality overlayment roofing membranes have to meet particularly high requirements. Such bitumen mixtures are typically produced from polymer-modified bitumen having an SBS rubber content of at least 10% by weight and may also have just a comparatively low filler content. | 11-18-2010 |
20110257307 | METHODS AND SYSTEMS FOR CONVERTING WASTE INTO COMPLEX HYDROCARBONS - A method for receiving animal waste from animal confinements or other concentrated animal waste sources and for converting the waste into a complex hydrocarbon is described. The waste contains both liquids and solids. The method includes separating the liquids and solids into separate waste streams, controlling an amount of moisture in the solids waste stream such that the amount of moisture in the solid waste stream is compatible with a selected energy conversion process, and feeding the moisture controlled solid waste into the energy conversion process. The complex hydrocarbon may be suitable for use as a substitute or additive to petroleum-based asphalt binder. | 10-20-2011 |
20110269876 | POLYMER MODIFIED BINDER AND PLANT MIX MODIFIER FOR ASPHALT AND PROCESS OF MAKING - The invention provides a polymer modified binder using an asphalt plant mix modifier comprising a mixture of thermoplastic polymers, comprising both elastomers and plastomers, blended with oils and dispersed in a powder medium to facilitate flow. The use of polymers in dry form has provides for a means of incorporating additives into asphalt that can be successfully performed within the normal range of temperatures used for the mixing and compaction of hot mix asphalt. | 11-03-2011 |
20120016062 | Binder composition comprising a low viscosity naphthenic oil for coloured hot-mix asphalt applications - The present invention relates to an essential colourless binder composition comprising a naphthenic oil having a total content of naphthenics of 35%-80% by weight, based on the total weight of the naphthenic oil, and a petroleum or synthetic hydrocarbon resin, wherein the ratio of the naphthenic oil and the petroleum or synthetic hydrocarbon resin is between 10:90 to 90:10. The essential colourless binder composition is suitable for use in coloured asphalt compositions and emulsions. | 01-19-2012 |
20120220700 | USE OF WAXES IN A CROSS-LINKED BITUMEN/POLYMER COMPOSITION FOR IMPROVING ITS RESISTANCE TO CHEMICAL ATTACK AND CROSS-LINKED BITUMEN/ POLYMER COMPOSITION COMPRISING SAID WAXES - The present disclosure relates to the use of 2 to 6% by mass of Fischer-Tropsch waxes in a cross-linked bitumen/polymer composition for improving the cross-linked bitumen/polymer composition's resistance to aggressive chemical agents. | 08-30-2012 |
20120252938 | MODIFIED ASPHALT PRODUCT AND PROCESS - An asphalt modifying binder product, which is essentially a ‘cut-back’ bituminous binder, uniquely including a petroleum product, such as diesel fuel or alternatively an organic oil, including vegetable or animal derived fats or oils, or glycol, for use in the manufacture of cold mix asphalt “CMA” and asphalt treated base products. When mixed with an aggregate, the product blends within standard gradation ranges. The product may be employed as a patching/paving material or an asphalt treated base, either of which stays pliable for extended periods of time, and again meets the typical required specifications and standards, for stability, flow and voids, when tested as hot mix asphalt or asphalt treated base. | 10-04-2012 |
20150112001 | MICRONIZED ASPHALT MODIFIERS, METHODS OF MODIFYING ASPHALT, ASPHALT COMPOSITIONS AND METHODS OF MAKING - An asphalt additive comprising a primary rheology modifying component and a secondary rheology modifying component, and asphalt compositions and products having such additive incorporated therein. The primary rheology modifying component is generally a polymer, and the secondary rheology modifying component may comprise a petroleum micro-wax. | 04-23-2015 |
20150322263 | ASPHALT UPGRADING WITHOUT OXIDATION - Disclosed are asphalts that are suitable for making shingles and other roofing material, i.e., coating asphalts, from harder paving asphalts, without oxidation of the paving asphalts. This is achieved by using various additives, including polyethylene waxes, low density and high density polyethylene materials, hard paraffin polyethylene, Sasol waxes, that are made using the Fischer-Tropsch process, and thermoplastic polyolefins that reduce brittleness at cold temperatures. | 11-12-2015 |
