Engineers call the existing ground where the pavement goes the subgrade. On top of the subgrade goes a new layer of unbound soil and stone, where the aggregates aren’t glued together.

In addition, these voids lower the aggregate density, meaning should a patch of pavement be kicked up the force it would inflict on windshields and headlights is much lower than conventional ...

Pavement can be opened to traffic immediately. Spray patching is done via a low-pressure system, which delivers the necessary air, aggregate and emulsion at a rate of just three to four PSI.
