A small 8' wide x 20' long area on the bottom of my driveway has large ruts on both sides that fill with water and get worst every year. The asphalt in the ruts is getting thin, and I'm looking to have it fixed. A contractor came and gave me an estimate to fill in the ruts level to the center of the driveway (the top most part) with stone then asphalt, or just asphalt depending on what he has left over in the truck when he is in the area. Is this a proper fix for this type of problem? I was interested in getting it removed, new stone brought in and a fresh base but he gave me a cheap price of $500 to do it this way. Thoughts?
