摘要： Asphalt compositions comprising reclaimed asphalt and an ester-functional rejuvenating agent derived from tall oil are disclosed. Rejuvenated binder compositions are also included. The rejuvenating agents restore to reclaimed asphalt desirable properties of virgin asphalt. Reduced glass-transition onset temperatures and improved creep stiffness in the rejuvenated binders translate to improved low-temperature cracking resistance in the asphalt. The rejuvenating agents impart desirable softening at low dosage while also maintaining acceptable penetration values. Dynamic shear rheometry results demonstrate that criteria for asphalt compositions under low, intermediate, and high temperature conditions can be achieved, and the asphalt will have good fatigue cracking resistance and rutting avoidance. The rejuvenating agents reduce the temperature needed to compact or mix asphalt compositions, which conserves energy and reduces cost. The rejuvenated asphalt and binder compositions enable greater use of reclaimed asphalt, especially RAP, and help the road construction industry reduce its reliance on virgin, non-renewable materials.

摘要翻译：公开了包含回收沥青的沥青组合物和由妥尔油衍生的酯 - 功能性再生剂。还包括复原的粘合剂组合物。恢复原料恢复到再生沥青所需的原始沥青性能。在复原的粘合剂中降低的玻璃化转变起始温度和改善的蠕变刚度转化为改善沥青中的低温抗裂性。复原剂在低剂量下赋予理想的软化，同时还保持可接受的渗透值。动态剪切流变测试结果表明，可以实现低，中，高温条件下沥青组合物的标准，沥青具有良好的抗疲劳开裂性和抗车辙性。复原剂降低压实或混合沥青组合物所需的温度，这节省了能源并降低了成本。复原的沥青和粘合剂组合物可以更好地利用回收沥青，特别是RAP，并帮助道路建设行业减少对原始的，不可再生的材料的依赖。
