Default Drive dump truck over lawn?

I am getting 5 tons of modified (crushed) stone delivered via dump
truck for a patio. I already have the area excavated, so most
convenient would be for the truck to dump right in the hole...but
would require driving over the rest of the lawn to get there. It's a
small(er) truck, but I still wonder if it is going to destroy the
lawn, especially since it rained hard last night. Any suggestions? I
really don't feel like transporting 5 tons of stone by myself if I
don't have to.

Thanks,

You're looking at somewheres in the neighborhood of 20,000 lbs of
weight, (and that's with a real small truck) on 6 tire with a contact
area of approx 50 sq inches per tire. *So that's about 66 lbs per square
inch. *And remember, the back is probably carrying more than the front,
so the number may be closer to 100 lbs per square inch. *You're gonna
have some nice ruts unless the ground is just rock hard dried out.

I agree that the you will probably be around 100 lb/inch^2, but I
think your area calc are off a bit.

I think the inflate tires on trucks to about 90 lbs/i^2 (unladen). If
so, 20,000 lbs on 6 tires would be 37 i^2 per tire, not 50.

50 i^2 at 100 lb/i^2 with 6 tires is 30,000 lbs.

If the inflate to 120 lbs/i^2, then of course your weight per square
inch will well be somewhere above that number.

I was just visualizing a 6x8 inch patch of contact. I've been around
truck tires all my life and don't need a bunch of technical jargon to
know how much tire is on the ground at a given time. Thanks for the input.

Technical jargon? The only term Pat used that you didn't is unladen.

Anyhoo, were you serious about being surprised that driving over tree
roots can damage the tree?

I for one don't understand what Pat was saying either. Aside from
dragging tire pressure into the picture, I don't see how tire pressure
actually got factored into contact area of the tires on the ground to
give any more realistic an estimate of the effects. Pat just made
another guess as to the exact area. Like Steve, I can tell you a
truck with 5 tons of load on a wet lawn isn't a good idea.

Good chance for a couple of tire ruts. I'd rather fix that than move 5
tones of stone by hand.

It's only three and half yards of gravel. If OP buys a wheelbarrow, only
loads it halfway, and spreads the work out over a week, it's not that big of
a deal.

If it is too much for the OP to handle on his own, school is almost out, and
there are a lot of young guys and burley girls running around who would LOVE
to make fifty bucks for a half day's work. Tell them they make ten bucks an
hour, and if it takes them less than five hours they get the whole fifty.

Thanks,


Generally speaking truckers take no responsibility for your lawn. I once
paid more for cleanup than for the cement that was delivered. I live in
the Princeton NJ area, and it looks like you might too. Due to the
recent rain the ground here will be wet here for at least another month.
I'd put off the delivery until the ground was dry. Failing that I'd have
the truck only enter my yard on temporary roadway...something like large
boards (to distribute the load).

If you can't do either then perhaps you could hire a small lawn
maintenance/landscaping company to move the stone by wheelbarrow (on
boards) across your lawn. It should be only about 75 wheelbarrow trips.

Because of their smaller tires, small trucks can actually do more damage
than larger trucks.

HTH,

EJ in NJ


Yes ruts. But filling them in and letting the grass grow back over
next couple of months may be a small price to pay!

It's only a bit of soil and some grass after all! Grass is expendable
and regrowable; in fact some horticulturists suggest that grass is a
waste of time, effort etc. and recommend seeding with clover instead.
Clover puts nutrients back into the soil and needs less cutting.

Trying to move tons of crushed stone by hand/wheelbbarrow etc. is
heavy work!

Putting down some old pieces of plywood etc. might help spread the
weght of truck tyres.

Buying crushed stone to be delived by a 'Stone Slinger' truck would
presumably be more costly?

Thanks for the replies. Yep, i'm in the princeton area and we did get
quite a bit of rain recently. I have several 16" wide plywood boards,
taht I think are actually OSB, 1/2" thick. I have enough to lay out
probably 50 feet at a time in parallel tracks for each tire, so might
need to move them once during the dump. Do you think they would be
sturdy enough to distribute the weight and avoid ruts? The big
problem is that they would need to cross my neighbor's lawn too - and
while they've said it would be okay, I don't want to be fixing their
lawn for the next 2 months as that might annoy them just a bit.
thanks again.

All I can say is that using the plywood will help. Unfortunately there
are just too many unknowns to make a firm statement. Most likely it will
be OK. The only acid test I know is to watch carefully as the truck
moves over the boards. If problems develop send the truck back and dump
the load for moving manually.

If your soil is like my "Princeton Shale" it is like soup when wet, but
it sets up like concrete when dry. When it is dry you can bounce bowling
balls off it. This is why I think you may be wise to wait till the soil
drys out.

I'd be very careful about the neighbors lawn..these things have habit of
becoming nasty when things go wrong.

HTH...Good luck.

Another thought..I think 1 inch of plywood would certainly do the job.
You could double it up in 25 ft runs, and I think you would be OK.

YMMV,

Thank you again for all the replies. The neighbor said that she
doesn't really care too much about her lawn (if you can believe
that). And I said that I would work my best to fix any damage, should
any occur. Perhaps I will double up the plywood to 1" thick and see
what happens. Moving the plywood several times is going to be a hell
of a lot easier than moving 5 tons of crushed stone via wheelbarrow.
And afterwards, I don't care about the plywood at all - I bought it
pretty much to sacrifice. Another bonus is that I have 2 pallets of
concrete pavers coming in before the stone - and they use a heavy duty
forklift - so I can see how that fares before increasing the weight to
a full truck. thx...I'll let you know how it turns out. Jus curious
- anyone know approx how many wheelbarrow trips it would take to move
5 tons of crushed stone anyway?

They covered this on This Old House recently where someone had to bring in a
rig to drill a new well. Yes, you should expect ruts. The soil will be
compacted enough that just shoveling dirt into the ruts and raking in grass
seed might not work as the grass roots will be fighting to get through the
compacted soil, plus the new grass might be visibly different from the old
grass so you'll end up with a striped lawn. Roger on TOH used a walk-behind
cutter to lift the sod, they roto-tilled the soil in the ruts and topped-off
with more soil, and then replaced the original sod.

I wouldn't expect 1/2" OSB to survive a loaded dump-truck's weight, but if
it prevents the tires from making ruts it's a cheap sacrifice. Paying a
day-labor crew to bring in the stone from the street with a couple of
wheelbarrows seems like a reasonable alternative if you want to avoid fixing
your neighbor's lawn, it would probably be cheaper than fixing ruts.

*In addition to what others said, I would be concerned about underground
utilities and sprinkler systems if those are in the designated path of the
dump truck.

Well i don't drive the trucks on the lawn often. AND i could really
care less if i damage a damn tree root. JEEEEzeee.. Hell we put a new
foundation under a house and cut several 4" roots CLEAN OFF and the tree
is just fine. Not high on my priority list to worry about.

Follow some of the ideas posted here that seem apropos to your area.
Overall, don't sweat the damage. Nature has a way of healing things,
if you just ignore it. Freeze-thaw cycles, wet-dry cycles, all have
the effect of leveling out irregularities. Right now I can see out my
window the pristine lawn my neighbor has in the area where a couple of
fully loaded ready-mix trucks delivered the concrete for his new
garage floor. Give Nature a little help and let her do the rest.

Joe
