I've done a couple driveways and sidewalks in the past, so figured I could do this, prob didn't need my nice concrete contractor. And because I estimated 150 yards of concrete, the concrete plant was more than happy to give me contractor pricing.
I spec'd out the drive to trace the old one so it would be 12 feet wide and in the areas where I always over ran it with the truck and trailers, I widened it to 14 to 15 feet. I wanted to never have to deal with this again and I hate cracked concrete. I frequently have semis delivering stuff, so I had to have it so that it could handle those loads, as well as my own equipment.
So 5000 psi mix with fiber (the fiber, well , just because it was only 7 bucks and should add strength) and 1/2 in re-bar at 12 inch spacing. The drive has a number of hills so I couldn't have the mix too thin, or it all would run downhill before I could get it screeded. I decided on 6 in thick as the goal. What the heck, if I don't have to pay the labor, may as well spent on materials. Besides made it easy to use 2x6 lumber to do the framing.
I could only do one truckload at a time, which was the only downside. Between the weather being too hot or rain or difficulty getting a helper, this project would take all summer.
It worked out that I could tear out old asphalt, grade, set up forms and set rebar in about 3 days for each section. I could get about 20 to 24 linear feet of drive done in one truck load.
By the time I coordinated with my helpers, I was down to one pour a week...at that pace it would take more than the summer. Later we were able to get 2 a week, and once 3.
My help included my daughter, who always engendered pity from the truck drivers, every one of them jumped down and grabbed a shovel when she was helping.
My other help, believe it or not was my financial advisor. He has intermittently helped me on various projects over the years, and he seems to enjoy the change from the button-down white collar job he normally does. He would come over on his lunch hour and pull the screed board with the best of them. Bless his soul
Here was our first pour. It really turned out horribly. I had never worked with fiber before and it made the cement the consistency of oatmeal. It didn't help that it was 90 degrees and we were in the sun. It was disheartening to put in all that work and have it look so bad...
Problem was it wouldn't float, it just stuck to everything. Part of the problem was that I had ordered it so thick to keep it from running downhill the other problem was that because it was a 5000 pound mix it had a lot more cement in it that I was used to, so it stiffened up really fast. Even with retarder in it, you only got about 15 minutes to work with it before it became unworkable. We definitely needed a new plan of attack.
