RAP already includes asphalt, albeit aged material that does not have the exact same homes of fresh asphalt.

As an example, the DSR enables item designers to produce toothpaste with the right uniformity to ensure that it can be squeezed from a tube yet not diminish the toothbrush. The DSR examinations binder placed between 2 parallel plates about the size of a quarter. Among the plates relocations and the machine determines the viscoelastic properties of the asphalt.
