MODIFICATION OF ASPHALT OXIDATION AND BINDERS WITH POLYMER WAXES
Asphalt can be modified by polymers, oligomers, and waxes made from polymeric material. The addition of polymer, oligomer, or wax can increase the softening point of the asphalt, decrease the penetration of the asphalt, and/or shorten the oxidation of the asphalt. In some embodiments, polymer, oligomer, or wax is added to an oxidized asphalt. The polymer, oligomer, or wax can be made by catalyticdepolymerization and/or thermal degradation of polymeric material. The polymeric material can be polystyrene, polypropylene, polyethylene, a combination of polypropylene and polyethylene or recycled plastics. In some embodiments, addition of the polymer, oligomer, or wax improves the performance grade of a paving asphalt binder alone or in combination with other modifiers such as ground tire rubber and polymers. The addition of wax can increase the high service temperature of the asphalt binder.
沥青能够被聚合物、低聚物和由聚合物制成的蜡改性。聚合物、低聚物或蜡的添加能够提高沥青的软化点，降低沥青的渗透度和/或缩短沥青的氧化。在一些实施方案中，将聚合物、低聚物或蜡添加到氧化沥青中。聚合物、低聚物或蜡可以由聚合物材料的催化解聚作用和/或热降解制成。聚合物材料可以是聚苯乙烯、聚丙烯、聚乙烯、聚丙烯和聚乙烯的组合物或再生塑料。在一些实施方案中，单独或与其他改性剂如废旧、轮胎橡胶和聚合物结合添加聚合物、低聚物或蜡提高了铺砌沥青粘合剂的性能等级。添加蜡能够提高沥青粘合剂的高使用温度。
