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.
