Rain has done a number on our home driveway. Nucor steel plant has slag that is available. Washed rocks are available. Part of the drive is fairly flat and some is on a slight grade. I am not sure what is best to use. Large gravel is also available. Any advise appreciated. Need to repair abou 150 ft. Thanks

as long as it doesn't get really muddy get some road base (3/4-1" with finer mixed in) and some portland cement.

spread the base 2" or more thick, spread portland on top, rake in (just needs to be mixed a little) and sprinkle with water lightly. drive over it to compress while damp.

this is a crude adaptation of how we used to do roadbeds for hiways etc. works extremely well and won't wash out easily. 150' x 12' should take about 20 bags of portland. just use a shovel to spread like you would sand.

Thanks hop. I�m on a post oak hill with hardpan iron ore. It�s not muddy But has wash down to red clay in running water spots.

I spread roadbed here, 4 loads I think, to build our driveway 25 years ago. No Portland Cement, and it is now like concrete.

I just built a temp drive that I plan on building on later. I will pave it later but I used wash out on it. It s like road base but cheaper. Road base for 5 tons was right at $125, 5 tons wash out was $10. Wash out is where cement trucks clean out the hopper at the end on the job or day. I cant tell the difference in it and road base.

Fill the potholes once they start showing up. Each time you hit a pothole it splashes out a small amount of your road. After a few weeks it has taken away several inches of road. Stay on top of your potholes when you first see them by filling them in so they don't continually get worse.

hop has a great idea with the portland.

Limestone flex base around here should have enough fines in it to lock it in if it is properly compacted, and should be readily available from any quarry. I would recommend renting a vibratory plate from United Rentals or the like, Grade the flex base out dampen it, a pretty good dose of water but do not flood it, and run that plate over it until your hands wont stop vibrating on their own. Depending on the source of the rock you might have to slush it to get the fines up to the top. That's a whole different conversation and then portland might be your best bet like Hopalong said.

Medium Granite Gravel is a good road base

In my field, we use Crush and Run (some call it Crusher Run). It holds up well under fully loaded tractor-trailer use with semi-annual spot filling and grading. I have to assume you can get 3 to 5 years on a residential driveway.
