I don't think so. for example, roads that are 20 to 30 years old do not have the same amount of AC as they did when they were first laid. Weathering and other factors wash out the A.c., hence why the road falls apart. RAP is just used to save money because AC is so expensive so if your mix design calls for 4.8%, and depending on municipality spec, you can only use a certain amount of RAP (I work for contractor who does work mainly in GTA Regio, Toronto canada). Adding A.C. is banned from Top layer and mostly used in Base or Parking lot mixes. Adding RAP also makes your not A.C. stiffer which could lead to stiffer asphalt, which can cause thermal cracking during weather cycles, summer to winter to summer. 

Also due to refiners becoming more efficient in extracting fossil fuels, AC gas become mire dilueted compared to 15 years ago. Companies such as yellowline and mcapshalt add POLYMERS  that help give the A.C. better properties to acheieve the correct propties needed in certain mix designs, especially superpave mixes
