Does this look like 5 yards?

[N1ST]

I took delivery today of 5 yards of 3/4" process and the pile is smaller than I expected. Does this look like 5 yards?

 

[tinkertoys]

Looks to me like it. I've hauled a lot of material. Should have been a single axle truck and one load.

I cannot answer directly but there is a way to estimate the pile. There is a number called the angle of repose (I think) which is the included angle between ground and the slope of the pile. It is different for different materials. You can probably find it on the net someplace. Then get the vertical height. It will be the volume of the cone but I thinks there are tables around also. I will look around myself and post if I find it.

If it helps, the pile is 10' x 15' x 3' at peak height.

I have a full sized loader backhoe with a 1 yard bucket and a single axle dump truck that is rated for 5 yards. From your picture, it looks like five yards to me. Might even be a little more when compared to what I move around on my land. Just looks a little "fuller" then my piles, but then the clay has a tendancy to stick to the bottom of my bed after a awhile and my piles tend to get smaller until I clean off the bed.

ahhh not going to work straight away. The angle of repose thing comes from gravel plant operations where a pile is created from a point source at the end of a conveyor .
For crushed gravel an average angle is 37 d
Vol of a cone is 1/3 ( base area) (height) Tangent of 37d is h/r
r would then allow calc of the base area.

However a cone is not a rectangular pyramid which is what you have.
But I still think it could be calculated
If 15 ' is the long dimension then 3 x 1/2(10) = 15 sq ft x 15 = 225 cf
divided by 27 cf per yard = 8.3 cy

If 10 ft is the width then 3 x 7.5 x 10 = 225 same.
Wow you got more than you paid for. course the pile is probably not even all a round but I would say you got 5 cy.
I buy by the ton and they weigh the truck I guess full fuel tank or empty would make a difference but then I usually get 22tons at a time and it really does not matter.
Hope I did this right .I am always worried I made some mistake and will look like a dummy.

Whoops looked at the pictures again the ends are tapered in. I would say you got 5 cy + a little
like Eddie said.

Kinda rough figuring. Take four piles like yours and put them together and they'll make a box type pile that would be 10'X15'X6' That would be 900 cubic feet. A fourth of that would be 225 cubic feet. Divide that by 27 (27 cubic feet = 1 cubic yard). That comes out to 8.333cubic yards. Allowing for some irregular slopes in your pile, I'd say that you have at least 5 yards.

Again, just rough figuring.

if your pile is 10' x 15' x average height of 1.5' then you've got 8 1/3 yds.
225/27

oops...i think tom and i posted at the same time

Well you guys have given me the good and bad news... Good is I got what I paid for. Bad is I may need to buy more and I'm not as good at math as the rest of you. Thanks.

the piles looks big but the sizing looks more like 1-1/4" minus... anyway i always get a truckload (14 ton) at a time which i think is equivalent to around 12yards. costs $220/load. a bit more for clean but not much. i wish i could find a cheaper source for rock and dirt, just seems silly to have to pay so much for it.. i dunno maybe it's just me..

 

[Tig]

I just had 6yds of the same material delivered. Looks about right to me.
Bigballer. My quarry sells the blasting scraps for $130 per load. For that I get a mix of shale (3"-) and clay. The dispatcher suggested it as cheap fill when I was asking for pit run (180 per load). It's just the mess they want to get rid of. Never hurts to ask.

What he didn't tell us was that there's a pit 27 feet deep and fifteen feet around that was filled before the gravel mounded up.

Evenin Cliff,
Thanks for saturday nights' chuckle !!!

You got a bargain! By my calculations, counting the number of rocks on the surface of the each of the three angles and multilpying by the square root of the total divided by 3.25, you actually have 5.125 yards.

 

[sandman2234]

Just looks like one yard to me, and it looks like it isn't going to be a yard much longer. Somebody has something in mind, dumping all that gravel in the yard??

No matter what it is, someone on here knows it. And then someone else on here knows it a different way to verify it.

Now I'm just waiting for someone to change a light bulb and see how many of us it takes.

It's a cone that has been split in half and a triangular section placed in the middle. The radius of the cone is 5 ft. We know that because the pile is 10 ft wide.

The volume of the cone is 1/3 base times height which is equal to 3.14159 x 5 x 5 x 3 or 78 cubic feet.

The center section is 5 ft long. We know that because the pile is 15 ft long minus the ten ft already allocated to the cone.

The volume of the center section is the triangle times the length or 1/2 base times height times length or 1/2 x 10 x 3 x 5 = 75 cubic feet.

The total is the cone plus the center triangular section or 75 + 78 = 153 cubic feet = 5.66 cubic yards.

I noticed that you live north of escondido. I lived in romona for about a year. Did the fire get up that way ?

I had fire within seven miles on three sides and was under mandatory evacuation but chose to stay. I had my escape routes planned and was well informed as to the status of the fires. I thought I would lose everything including the tractor. I moved my implements to an open area in the field but left the tractor in the garage.

To make matters even more complicated... Almost all fill material I have ever purchased was sold by weight, almost has to be to be legally transported and comply w/DOT regulations. I have purchased processed material w/weights anywhere from .86 to 1.25 ton per cubic yard.
And don't forget about compaction as I did early on in my career "DON'T FORGET COMPACTION, IT ADDS UP FAST" I was told by the boss! Usually somewhere between 8% and 12% for processed rock depending on percentage of fines in my experience.
