Whilst it may be fair to class tar & chip as a form of ‘bonded stone’, this would be akin to saying that high quality epoxy paint and whitewash are both surface coatings.
The main problem with tar & chip surfaces is that the process uses a cheap bituminous glue that, whilst having poor long term adhesion qualities, re-melts in warm temperatures causing black ‘tracking’ under vehicular and pedestrian traffic. You just have to look at the state of the country roads on hot days that have been covered with tar & chip to appreciate this.
A very popular offering with unaccountable and cold-calling driveway contractors, tar & chip coatings may look fine for a short period of time and generally these disreputable companies will leave a thick layer of loose stone on top of the completed surface in order to mask the inevitable problems.
