Asphalt

[Gizmo36]

I can get some Asphalt for free. But they will bring it out and dump it.if I spread it and don't pack it will it work ok. has any one ever tried this. I put this in the wrong place can some one move it to Projects.

 

[SkyPup]

Nope, you'll need to roll it.

 

[Gizmo36]

How much weight would it take to work ok.

In the absence of a roller, I'd roll it with my car/truck after attempting to mash it while spreading it. Bald overinflated tires would be good. Um, is this "hot" mix or "cold" mix (aka road mix, patch mix)? Cold mix is good, for your situation, hot mix could be a nightmare.

I agree.. 450-300' hot asphalt is going to be a pain to work. if it was a small area you could loop and tamp it.. on a large area.. a roller is needed. Trying to roll with a tire is going to make an ugly rutted mess that will setup black and hard...

I too had explored this option, however after researching several web sites it became apparent that there is a potential health hazard if it is not installed and sealed properly. In that the fines can be blown in the wind, or be introduced into the water table.

It is cold mix,Would 450p roller be good.

I just sat my Mother-in-Law on a toyota hood and dragged her her back & forth. If you're interested she'll work for several buckets of KFC.

 

[Gizmo36]

With mine and your's that should work ok. because my Mother-in-Law is big.

Man, I have got to hear the rest of that story!

Anything would be better than nothing. Just get a feel for the material before you get too involved. The roller will have to overcome the footprint of your tractor, obviously. Pick a time of day that you feel the material will work for you. I like the car and ballast! Modifying my previous post, if it's too mooshy, drop tire pressure to 10 psi to minimize ground pressure. When smooth, raise tire pressure and ballast and/or speed to compact more.

Cheers!

For "Cold mix"

Rent a vibrator roller packer that will fit in the back of a pickup.

Lay out the cold mix as best you can. A backblade would help. Then pack it. Spraying a little water over the rollers while packing would be a good idea. A little diesel fuel will help clean the equipment when you are finished.

Note: There will be asphalt on everything you touch as it magically adheres to boots, clothing , skin etc.

Hmm funny.. I've laid asphalt for ... 18 years.. never heard that one.....

Not many fines in asphalt.. at least none that aren't entrained by the bituminous mix.

Cold pack will be thick .. thicker than stuff from the cooker... Cold pack will have a longer work time, and is a little more forgiving when tamping down.

Most asphalt products become realitively environmentally inert once cured..

Depends on contact surface area.

I'd try renting a small sod roller...

I've rolled small driveways with one... not the best.. but works.. Keep water on the drum.. prevents sticking. A pump up garden sprayer works for this pretty good..

You are correct, asphalt contains about 95% crystalline silica, the causative agent of human pneumonoccal silicosis. Normal limestone, cement, concrete, etc. only contains <1% crystalline silica. Inhalation of the crystalline silica causes irreversible silicosis of the lungs, a major hazardous danger for asphalt plant workers, which is strictly regulated my OSHA.

The maximum air concentration of cyrstalline silica is 0.05mg/cubic meter of air, while other allowable inhalable particulates are generally at the 10mg/meter of air level, showing how seriously dangerous crystalline silica is.


Sound, you've been working with asphalt for 18 years and did not know about silicosis? That is about the normal incubation time before the disease develops, you may want to go see a pulmonary specialist and get your lungs checked.

Also, it is the fines you cannot see that kill you, just because you cannot see them doesn't mean they are not there.

Is he talking about making the asphalt.. or having it delivered pre-made.. I've seen it dumped out of the back of trucks for 18 years.. already cooked and hot.. I'm not involved with plant operations where it is made.

I don't see how the hazards associated with making it have any bearing on the guy standing by his driveway waiting for the finish product to be dumped out.

The owner of the largest cement and asphalt plant in our town has emphysema.. but then.. he has owned and worked at his plant for 50 years... His health problems are not a surprise. The guys ont he job laying the cooked product.. I just havn't seen any issues with it.

So.. to clarify.. Are we talking about finish product? or is the guy getting the cold patch delivered having a mobile plant show up.. and refine the stuff right there at his driveway and then dump it.. or is he going to the plant.. helping to make it.. then bringing it home to dump out?

( lets be reasonable here... I think we all know that the guy is getting the finish product delivered )

( on another note.. about the vast differentc in dangers of finished products vs component chemicals... Google popcorn butter, and find out how bad the fake popcorn butter in microwave popcorn is for the workes that make it.. yet virtually harmless to the person eating the finished product... unless you count the salt and fat.. etc. )

There are at least a dozen mixes for asphalt.. .. Everything from surface coarse to traction coarse.. different dot grades.. asphalt with terra cotta.. asphalt with reclaimed tire..e tc.. Low iron asphalt... I think you need to be a tad more specific before making that blanket statement that asphalt contains 95% of anything.

As for my lungs.. they are fine.. i get my checkup 2x a year... thanks for the concern.

Silicosis is 100% irreversible.

Better try a search on Medline or the National Institues of Health's Library of Medicine instead of Goggle.

Here's an MSDS on Asphalt for you to ponder.....

Did you read it.??????. perhaps the part where the inhalation hazards are from the incomplete constituant components.. not the final product. Or.. if you are reclaiming the asphalt ( grinding, crushig or cutting ) you can release some of the silica into the air.. .. that's it... Tamping hot or cold asphalt dosn't produce a silica hazard.. take the red herring some place else.

Without the proper engineering controls, safe work practices, training, and respiratory protection, the asphalt worker becomes the red herring.
