A. We've got you covered on this one. Stabilization fabrics
are the answer. These products were developed to improve the
stability of the aggregate base.
The way they do this is by separating the layers of the aggregate,
confining the aggregate (not allowing it to move) and more
evenly distributing the load. By doing this, stabilization
fabrics minimize ruts and soft spots and increase the allowable
stress on the subgrade. Further, they save job costs by decreasing
aggregate requirements and eliminating the need for undercutting.
The way to sell this to the customer is that they will have
lower maintenance costs down the road - and less soft spots
to begin with.
They're easy to install. Basically, all you do is roll the
fabric over the prepared subgrade with overlaps of 1 1/2 to
3 feet depending on the condition of the subgrade. Then dump
the aggregate onto the fabric, spread it, and compact it using
regular techniques.
