I need info on a good way to repair cracks on an asphalt driveway. There are numerous 1/4" cracks and hairline cracks on the asphalt driveway in the area where the driveway meets the street. I have tried driveway patching material (comes in a bucket) and sealant (comes in a bottle or in a tube), and I have also put driveway sealing paint over the driveway. And I have done this twice during the past 5 years. Noon work. The cracks will come right back after a cold winter (I live in northern New Jersey). I need to find a good way to repair cracks that the cracked can stay fixed for at least two years or more. What's that wonder product?
If there is no DIY solution available, please tell me whether I should hire a contractor to do this, and what type of contractor I should hire. What kind of method or product should I expect him to use to have a good result?
Thanks in advance for any info.
