Driveway Surface

Could have been bulk cement or lime Ed but I bet it was fly ash most concrete plants have silo's full of the stuff it looks like cement with about the same texture

good luck

practice around my area is to use Kiln dust or lime for ground stabilization..the Kiln dust seems best:It is the by product of the cement production process...amazing results..usually overkill for our bus weight..some type of Geo mat or typar with stone will usually do job..My drive is 800ft long base is #2 limestone 5 inch thick and choked on top with fifty threes (mix of sizes and fines) about 3 inches thick.In some areas of country it is called compaction rock  or dense grade..     wind blown silt formed a yellow clay  area where the glacier's ended during the Ice age..

You must have a lot silt,high plasticity and clay soil in your area Bob that is about the only time we used kiln dust was to lower the PI of the soil


good luck

I know that it wasn't bulk cement or lime, and probably not fly ash. I am leaning more towards kiln dust, that is kind of ringing a bell. Oh wait! my ears have been ringing since 1970.   Hard to remember details from 11-12 years ago!

Ed,

Maybe you could have your lungs tested to see what you've stored up there.

Maybe Beninite s/p I used it in a arena once and it got hard as a rock . I did as you mentioned worked it into the dirt and watered it and rolled it . just a thought

A friend hauls road millings (road-a-mill in this area). He has to pay for it and has been storing it on his company lot. I had him deliver about 300 yards a few years ago. It eliminated all the mud and dust and has not settled at all. Spread it with my tractor with bucket and rake. It has been through 2 winters of snowplowing, freeze and thaw and gets harder every year. Even my leaky Detroit Diesels don't seem to bother it.

We love it!!!

Road a mill? That looks like asphault grindings.... at least that is what we call it, if it is the same stuff. The price sounds about the same too. But with ours it just stays a million little rocks... For the people with rock drives (or other organic), what do you do about weeds and rocks getting into the house and your vehicles?

I used crushed concrete as a base for my 400' driveway.

A little rain or watering and a plate compactor or roller makes for a very smooth and hard surface.

I see anytime around here that they tear down a large structure that they crush it on site.

Usually have a contact number posted.

They used to almost give millings away, until they started recycling it into new asphalt.

I think it was almost 400.00 for 18 Yds last time I checked, delivered.
