My driveway is 1/4 mile long and I have these estimates, on average: Tar & Chip - $15,000 Asphalt 2" - $21,000 Asphalt 3" - $30,000 My parents had 2" asphalt for 25yrs+ and we used to have logging trucks coming in and out of the farm for a while but mostly residential vehicle traffic and held up well. Tar and Chip is how most of the back roads were but then again, its got layer after layer and not a fair comparison. Me? I'll be running an International, loaded at 26k, over it about twice a week and empty at 17k the rest of the week. The rest will be cars, pickups etc and not usually more than 10k. On occasion I tow 14k behind my truck but that's just moving the Bobcat on/off the property for jobs.......not often. So, I'm stuck with what to do. My 21A base is solid, wet, but solid.........dang rain and snow. Once things dry up, I'm ready to go. Asphalt at 2" I didn't think was enough but it held up great for my parents and 3" is too much $. Should I be considering tar & chip?
