Recycled concrete vs gravel

[tallyho8]

Do NOT use crushed asbestos shingles anywhere. They must be buried well underground to be safe. No city had more asbestos shingle roofs than New Orleans and no other place filled as many pot holes with them and no place else has as much lung cancer.

As you run over the shingles they turn into asbestos dust. Then on a dry day it looks like a dusty driveway as you drive over them except it is toxic asbestos dust spreading contamination far and wide.

Very, Very, Very unsafe!

We recently patch some areas of our community road using recycled concrete and asphalt. That resulted for three brand new sets of tires for me, all are caused by the new crush concrete my neighbors used. Somehow the edge you get from the crushed concrete are very sharp, not sure if this is inherit to the crusher. Be sure to compact them well. I never had this problem using the crush rocks.

Sometimes that recycled product contains rebar or wire that was once in the concrete... Some years back a contractor friend had a portable crusher to recycle concrete... As time went on some job specs started requiring the product to be Metal Free... He installed an electric magnet and I wired it for 10 loads of RCR6 (recycled crusher run) ... Great Product, I still have 4 loads stock piled...:thumbsup::thumbsup:

We have been using crushed concrete around here as well and it makes an excellent road bed.
Recycled asphalt is also very good over a decent base.
Problem now is that the concrete plant is buying all they can get as somehow they are also stockpiling for some future usage.

Never heard of it, but I'd avoid it for paving a driveway or walk. Asphalt shingles have too much fibrous material and not enough tar. I would think it wouldn't compact very well and would have a spongy feel to it.

What do they advertise it to be used for? I can't think of any.

anyone ever heard of crushed or ground shingles? A place around where I live sells them and wonder how they work. Tracking to the house etc. . Most contractors are all into the green of recycling and probably alot of federal funds involved for political reasons, but have never seen any human results from the crushing, fiberglass inhillasion,asbestos, or personal use of the product. Could I track asbestes or other into the house from my recycled shingle driveway? Alot of questions arise in my mind, and don't get me wrong about recyled products, most are good, but what is the risk to us or others in the production and use? Guess there could be another government task forse created and paid for by us, but it seems they should have already been on top of that. Are they?

Actually, asphalt shingles have a high percentage of reuseable tar (or asphalt content). Finely ground shingles, with EPA testing for asbestes are used in todays roads. Something alot of people are not aware of and the fiberglass dust and inhilation at the crushers production facility is never tested for that, or maybe never considered a human concern. Just the asbestes. I'm just saying alot of life threatening problems could be stopped if the agencys involved to protect us from this would see the realality of this. Someone working at a factory or manufacturering plant is not aware, and really has no choice other than quitting and hunting for another job. End process, the consumer is pointed in the wrong direction ( asbestes ) rather than the other problem of fiberglass inhillation. I may be wrong, if I am please correct me.

There is a place in my town that converts waste materials to road maintenance and landscaping products. For driveways, parking lots, etc, they sell a product called C&R, which is 3/4" and finer crushed concrete, asphalt shingles, and some brick mixed in. Its' pretty reasonable, about $8 cubic yard delivered. Between my mother's and my driveway, I've spread about 140 cubic yards of it. This place rejects asbestos shingles, so that should be a non issue.

Some foreign material has gotten in there, like pieces of ceramic and thick rounded pieces of glass, but the last couple loads were pretty clean and I have never seen any metal in it. It can be pretty smelly when its delivered, but the aroma dissipates.

My mother's driveway is shorter than mine and has thicker layers of the C&R material laid down presently. We are now entering Mud Season in Maine and my stepfather is thrilled at how there is no mud in their driveway. We have also noticed the cars stay cleaner and less dirt is tracked into the house with the C&R material down.

The C&R spreads on darker when its moist, but it does gray-out over time as it dries out. Here's a picture of my mother's driveway after the first load of C&R was put down and spread with a box blade. Once we thaw out a little more I plan on ordering another truck load to put down at my house.
