Frequently Asked Questions (FAQ’s)
Question: Can an asphalt overlay be placed over a roadway with an existing chip seal?
Answer: Placing an overlay on a road with an existing chip seal surface is not unusual and for some standard practice. The tack coat is the most important issue. Get it even, apply it at the correct rate, use the proper materials, make sure it is set and make sure the surface is clean and dry before you start. No problem.

Rising Oil Prices,
Highway Funding Lapses
Underscore Pavement
Preservation’s Advantage
(From the Pavement Preservation Journal, Spring 2008)
The price of crude is at record highs,
highway budgets are signifi cantly
down, and there are concerns that the U.S. economy
is slipping into a recession.
I am asked all the time how that will affect the
paving industry.
In the past, when we have been faced with
this situation, many highway agencies would
cut maintenance budgets to protect funding for
capacity projects.
