The technique provides a coarse, sandpaper-like surface designed to improve friction and reduce the likelihood of traffic running off the road.
The process will begin with cleaning the road surface. An epoxy will then be applied followed by the application of small, coarse gravel to the road's surface.
The road will remain open to traffic, and flaggers will direct motorists through the work zones. Motorists can expect delays. The contractor uses an epoxy, so traffic accessing from adjacent roads and driveways can expect up to a 15 minutes delay.
Work is weather-dependent.
