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： The present invention provides a method for preparing an asphalt and thermoplastic elastomer composition. The process comprises heating an asphalt cut in a stirred tank to a temperature sufficient to allow the stirring of the asphalt in the tank. A thermoplastic elastomer or rubber is added to the asphalt while continuing to stir the asphalt. The mixture is stirred at a speed and for a period of time sufficient to increase the distribution of the elastomer into the asphalt. The stirring speed is reduced and the temperature is increased to add crosslinking agents to the tank. Stirring is continued for a period of time sufficient to improve the distribution of the crosslinking agent dispersion in the asphalt. Crosslinking agents include compositions of mercaptobenzothiazole, zinc oxide and elemental sulfur; compositions of mercaptobenzothiazole, zinc oxide, and mixed polythiomorpholine; and compositions of zinc 2-mercaptobenzothiazole and dithiodimorpholine.
摘要翻译：本发明提供一种制备沥青和热塑性弹性体组合物的方法。该方法包括将在搅拌槽中切割的沥青加热到足以允许在罐中搅拌沥青的温度。在沥青中继续搅拌沥青时，加入热塑性弹性体或橡胶。将混合物以足以增加弹性体分配到沥青中的速度搅拌一段时间。搅拌速度降低，温度升高，向罐中加入交联剂。搅拌持续一段时间，足以改善沥青中交联剂分散体的分布。交联剂包括巯基苯并噻唑，氧化锌和元素硫的组合物; 巯基苯并噻唑，氧化锌和混合多硫代吗啉的组成; 和2-巯基苯并噻唑锌和二硫代二吗啉的组合物。
