摘要： Asphalt and elastomeric polymer compositions crosslinked with mixed polythiomorpholines or at least one alkyl polysulfide can give polymer modified asphalts (PMAs) with improved properties and/or reduced H2S evolution. When at least one alkyl polysulfide is used to completely or partially replace conventional crosslinkers such as S or MBT, mercaptobenzimidazole (MBI) may be optionally used as a co-crosslinker. The use of mixed polythiomorpholines as crosslinkers provide PMAs with better low temperature profiles (BBR m-values). The use of at least one alkyl polysulfide crosslinker gives PMAs with improved PAV-aged DSR results, and reduced H2S evolution. The use of at least one alkyl polysulfide crosslinker together with MBI may give PMAs with improved PAV DSR Fail Temperatures.
摘要翻译：用混合多硫代吗啉或至少一种烷基多硫化物交联的沥青和弹性聚合物组合物可以得到具有改进性能和/或降低的H 2 S进化的聚合物改性沥青（PMA）。当使用至少一种烷基多硫化物来完全或部分替代常规交联剂如S或MBT时，巯基苯并咪唑（MBI）可以任选地用作共交联剂。使用混合的聚硫代吗啉作为交联剂为PMA提供了更好的低温谱（BBR m值）。使用至少一种烷基多硫化物交联剂使PMA具有改进的PAV老化的DSR结果，并降低了H2S进化。使用至少一种烷基多硫化物交联剂与MBI一起可以使PMA具有改进的PAV DSR失败温度。

摘要： In methods of preparing asphalt and elastomeric polymer compositions such as polymer modified asphalt (PMA), it has been discovered that the compatibility can be improved by adding excess amounts of certain organic and inorganic metal salts beyond the proportions normally used. Suitable metal salts may be metal oxides that include, but are not necessarily limited to, zinc oxide, calcium oxide, and the like. The method of the invention also permits asphalt modified with other polymers such as ground tire rubber (GTR) to have improved compatibility. Additionally, the use of excess amounts of these metal salts helps control gel formation.

摘要： An asphalt/aggregate composition having enhanced adhesion characteristics and its preparation. An asphalt base material is heated to a molten state in order to permit mixing of the asphalt with added components. A heavy metal soap is incorporated into the asphalt base material to enhance the adhesion of the asphalt base material with an aggregate component which is mixed with the asphalt base material to provide an asphalt/aggregate blend. The asphalt and aggregate can be blended together in a mixing chamber to provide a fluid asphalt/aggregate concrete which is then dispensed on a substrate surface or the asphalt base material and aggregate components can be separately applied to the substrate surface to provide the ultimate asphalt/aggregate concrete. The heavy metal soap is a C14-C18 heavy metal soap such as zinc stearate. Zinc oxide may also be added to the asphalt base material in an amount which is less than the amount of zinc stearate. The asphalt base material may be polymer-modified asphalt and may incorporate a crumb rubber component to provide a rubber-modified asphalt.

摘要： A method for preparing a homogeneous blend of asphalt and ground tire rubber. An asphalt base material is heated to a temperature sufficient to permit the stirring of the asphalt base material within a mixing vessel. A particulate crumb rubber component having a designated average particle size is added to the asphalt base material. The crumb rubber material can be partially devulcanized or partially depolymerized and may be accompanied by the incorporation of another rubber component, such as a ground styrene butadiene rubber. Zinc oxide is added to the asphalt base material. The mixture incorporating the zinc oxide is stirred for a period sufficient to provide for substantial solubilization of the crumb rubber within the asphalt base material to provide a blend which has a higher homogeneity than a corresponding blend of the same asphalt and particulate rubber components which is heated and stirred under the identical conditions, but without the addition of the zinc oxide.
