I've had an asphalt driveway for about 12 years (New Jersey). Several years ago several cracks started appearing, and in winter you can see dirt come up through the drive when wet. I pulled up and replaced one
10 square foot cracked section (there are several others); in places it was only 3/4 inch thick. I'm guessing that this is the cause of the cracks and that the base is good. The original drive was supposed to be 2 inches thick.I'm planning on having it paved over with an additional 2 inch finish coat of asphalt. Here are my questions:
- Should I have contractor pull up remaining cracked sections and make sure base there is sound?
- Should I ask for the end at driveway entrance and end at garage be pulled up so new layer is at the proper height?
- Is 2 inches a good thickness to request? How can you tell if they deliver the correct thickness?
- Any other recommendations? Thanks... Tom
