This article is just plain wrong and kinetics explains why there is no reaction between the rubber and the bitumen pavement. To further illustrate this point, old tire rubber is used as a viscosity modifying agent in a number of bitumen related products like rubber bitumen binder.
To produce rubber bitumen binder, the bitumen is heated to approximately 190°C to 210°C, at which the tire rubber is added via a hopper system into a pre-mix tank. This bitumen-rubber blend is then transferred into a curing (usually called reaction tank, but there is no real chemical reaction between the rubber and bitumen on the above mentioned process circumstances) vessel where it absorbs the lighter fractions of bitumen.
When you make an alloy of 2 metals you have a physical change in the crystalline arrangement of the atoms not a chemical one, bitumen and rubber interact the same way. Oh and with kinetics the ways to speed up a reaction are pressure and heat, so the chances of a reaction happening at the low temperatures and external pressures of our tires is almost non existent if there is no chemical reaction at 200 dec C.
