| 524069000 | Solid polymer derived from ethylenic reactants only at least one of which contains a carboxylic acid or derivative | 14 |
| 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 |
| 20110009534 | PROCESS FOR DEWATERING A MINERAL SLURRY CONCENTRATE AND INCREASING THE PRODUCTION OF A FILTER CAKE - The present invention provides a process for dewatering a mineral slurry concentrate and increasing the production of the resulting filter cake consisting essentially of mixing an aqueous mineral slurry concentrate with an effective amount of a nonionic surfactant and an effective amount of a cationic polymer to form a nonionic surfactant and cationic polymer treated aqueous mineral slurry concentrate, and subjecting the treated aqueous mineral slurry concentrate to a liquid water removal process for dewatering the treated aqueous mineral slurry and for increasing the production of a resulting filter cake of the dewatered mineral slurry. An improved mineral slurry concentrate composition and an improved mineral concentrate filter cake is also disclosed. | 01-13-2011 |

The compositions of asphalt mixtures in accordance with the present invention provides a manufacturing, spreading and compaction lower temperatures up to 70° C. compared to the temperatures used in the production and application of conventional hot mix asphalt used in paving and road asphalt concrete overlays. | 08-01-2013 |
| 20140135431 | ASPHALT COMPOSITIONS WITH CRACKING RESISTANCE ADDITIVES - Methods are provided for upgrading the quality of an asphalt. The methods include mixing an asphalt feed with a cracking resistance additive that improves the low temperature properties of the asphalt while leaving the high temperature properties unchanged or minimally changed. The cracking resistance additive corresponds to a compound that is a liquid at both the low temperature performance grade for the asphalt and at mixing and/or storage temperature for the asphalt. Examples of compounds that, in an appropriate molecular weight range, are liquids across this broad temperature range include polyalphaolefins, alkylated naphthalenes, and organic esters. | 05-15-2014 |
