I posted here a couple of weeks ago asking about the feasibility of
installing a driveway in two phases. Phase one would be the excavation
and laying of a suitable base for a property which borders wetlands to
be done in the fall. Phase two would be laying the asphalt in the
spring after the winter thaw and after adding more base to re-level
any low spots caused by thawing and soft ground.
After doing more reading on the subject, I have some follow up
- Is it better to remove more soft topsoil and increase the
size of the base. Note the water table under part of the driveway is
only about 4-5 feet below ground level and may even be less during
- Is installing drain tile an option? Knowing that water can
move in both directions, will this serve to increase water under the
driveway rather than take in away.
- Should some type of edging be used to protect the sides of the
- Should geo-textile fabric be used? Some contractors have said
it's a waste of money and they don't recommend it. Some say it may
- Is an asphalt base rather than a crushed stone base a better
way to go? If so, how many inches deep should it be. I was planning to
use about 12" of crushed stone.
- One contractor spoke of "process material" which he described
as a concrete-like material which hardened when wetted. Is this in
addition to a gravel base or instead of a gravel base?
Thanks again for any responses.
