Equipment Used, & the Process Explained
to Restore a Driveway Using Existing Gravel.
The first step involves the use of a piece of equipment we've invented that is similar to a “Box Grader”.
Currently we are in the works of securing a patent on a much improved version.
The 6 teeth (scarifiers) are dropped down & begin to score & ultimately pulverize the hard packed driveway back to loose gravel that had sunken, moved, & been unevenly packed after years of traffic & weather.
As the work progresses, the gravel begins to build up in the box immediately behind the scarifiers.
Behind the teeth is a leveling blade. After the surface is sufficiently broken apart,
the teeth are raised, & the blade lowered. Making several passes,
the holes are filled, the ruts removed, & a final grade is applied;
Thus evening out the newly recovered rock & finer particles needed to hold a driveway together.
The final step involves the use of a 4000 lb steel roller, which sets the gravel in place,
allowing very little movement until the rains come, settling the finer particles & cementing the gravel back where it is intended.
