    Abstract: Asphalt binders and methods and systems to produce an asphalt binder that has an increased resistance to fatigue cracking and thermal cracking. In embodiments, a method includes, operating a distillation tower to produce an asphalt binder and transporting the asphalt binder to storage. The method may include determining a phase angle of the asphalt binder. The method may include, in response to the phase angle of the asphalt binder being less than a selected threshold, adding one or more amounts of tower bottoms or gas oil to the asphalt binder to adjust the phase angle of the asphalt binder to and produce a fatigue and thermal cracking resistant asphalt binder and then releasing the asphalt binder from the storage. The method may include testing a sample of the asphalt binder aged for a selected number of hours in a pressure aging vessel to confirm the asphalt binder meets specification requirements.
