20080287570 | METHOD OF MAKING AND USE OF A HEAVY DUTY PAVEMENT STRUCTURE - The present invention is directed to a heavy duty pavement structure comprising an open-graded asphalt layer fortified with a non-segregating grout mixture. The heavy duty pavement structure is made through the steps including forming an open-graded asphalt layer and then fortifying the layer with a non-segregating grout mixture that includes a predetermined amount of portland cement, sand and cement binder system. | 11-20-2008 |
20090068348 | WARM ASPHALT BINDER COMPOSITIONS CONTAINING LUBRICATING AGENTS - The present invention provides a functionally dry warm mix asphalt binder composition modified with lubricating agents or additives that can be mixed with aggregate and compacted at temperatures substantially below asphalt binder compositions that do not contain the disclosed lubricating additives. | 03-12-2009 |
20090215931 | PROCESSING BITUMINOUS MIXTURES FOR PAVING AT REDUCED TEMPERATURES - Bituminous paving mixtures containing lubricating agents or additives may be prepared at hot mix temperatures and cooled, paved and compacted at temperatures 10-55 Celsius degrees lower than the hot mix temperatures. The increased temperature range between the hot mix temperatures and the paving and compacting temperatures is facilitated by the improved compacting properties of the paving mixture when it includes the lubricating agents or additives. | 08-27-2009 |
20100055304 | PROCESS FOR COLD-IN-PLACE RECYCLING USING FOAMED ASPHALT AND LUBRICATION ADDITIVE - Cold-in-place asphalt recycling is disclosed. A foamed asphalt may be produced by injecting water and optionally compressed air into a hot asphalt stream. A lubricating surfactant may be added to the hot asphalt stream to improve performance. The foamed asphalt may be mixed with reclaimed material to provide a uniformly coated paving material that can compacted to a desired density. | 03-04-2010 |
20110017096 | WARM MIX ASPHALT BINDER COMPOSITIONS CONTAINING LUBRICATING ADDITIVES - The present invention provides a functionally dry warm mix asphalt binder composition modified with lubricating agents or additives that can be mixed with aggregate and compacted at temperatures substantially below asphalt binder compositions that do not contain the disclosed lubricating additives. | 01-27-2011 |
20110020537 | WARM MIX ASPHALT BINDER COMPOSITIONS CONTAINING LUBRICATING ADDITIVES - The present invention provides a functionally dry warm mix asphalt binder composition modified with lubricating agents or additives that can be mixed with aggregate and compacted at temperatures substantially below asphalt binder compositions that do not contain the disclosed lubricating additives. | 01-27-2011 |
20110021673 | WARM MIX ASPHALT BINDER COMPOSITIONS CONTAINING LUBRICATING ADDITIVES - The present invention provides a functionally dry warm mix asphalt binder composition modified with lubricating agents or additives that can be mixed with aggregate and compacted at temperatures substantially below asphalt binder compositions that do not contain the disclosed lubricating additives. | 01-27-2011 |

20110243661 | STABLE EMULSIONS FOR PRODUCING POLYMER MODIFIED ASPHALT - An acid modified asphalt binder is combined with an emulsifier solution to produce an emulsified asphalt binder. The acid modified asphalt binder may be formed by combining an asphalt binder, a phosphorous-based acid, and, optionally, a polymer modifier. The emulsifier solution may be produced by forming an aqueous solution of an amine and a phosphorous-based acid, which forms an aqueous solution comprising an amine phosphate. The emulsified asphalt binder may be combined with an aggregate to form a paving material. In other examples, the emulsified asphalt binder may be used alone, for example in a chip seal application, or in a diluted form, for example in a fog seal application. | 10-06-2011 |
20120213584 | PROCESSING BITUMINOUS MIXTURES FOR PAVING AT REDUCED TEMPERATURES - Bituminous paving mixtures containing lubricating agents or additives may be prepared at hot mix temperatures and cooled, paved and compacted at temperatures 10-55° C. lower than the hot mix temperatures. The increased temperature range between the hot mix temperatures and the paving and compacting temperatures is facilitated by the improved compacting properties of the paving mixture when it includes the lubricating agents or additives. | 08-23-2012 |
