2) It removes a thin layer of aged hard rubber,
and reveals fresh soft sticky rubber.
If it removes a layer of rubber wouldn't that also remove the TrackBite?Â
They spray the track with TrackBite, not
the tire. You do a burnout principally to remove
this aged layer of rubber, particularly on the
first run of the day. On subsequent runs, you can
do a smaller burnout to just heat the tire surface.
For a national event, they spray the
entire 1/4 mile length of the track. For a local
bracket race, they just spray the launch area.
Maybe 100 ft. Whole different procedure.
Track surface preparation is an art.
They first clean the track surface with a rotary
sweeper. Then they spray the track with a layer
of TrackBite. Then they apply a thin coating of
rubber dust. Next, they burnish the surface with
a set of counter-rotating drag racing slicks.
Finally, they apply a very light final spray of TrackBite.
When the track is prepared optimally,
the traction (adhesion) is so great that you will
actually spall off little pieces of the
underlying concrete. Basically, the you exceed
the shear strength of the pavement material itself.
