I am going to do my first gravel drive way, and I need some help.
The owners want the old gravel taken out and replaced with new red gravel something along those lines. They also have a couple of spots in the drive way that they say always sinks back down and holds water, a couple of weeks after they put more gravel in it. What would cause this. Would all I have to do, is take the old gravel off, grade it, and put the new gravel down??
The drive way is 28 ft wide by 55 ft long, and I was wondering how much gravel I would need to cover it.

As I said this is my first drive way and please tell me if I missed anything else that needs to be done. Thanks in Advance :)

I would get around 10/15 yds. What I've done in the past is dig out and add RCA and compact it then add the colored gravel on top for show

alldayrj: thanks, how much does 10-15 yards of gravel usual cost.
I don't mean to sound stupid, but what is RCA:hammerhead:

Recycled concrete aggregate. Some people will also tell you to use geo fabric.

Around here the colored stuff is around 65/yd but i would double check that locally. I can't see your location on my phone.

What is it that your business normally does?

alldayrj: I live in a small town in Utah called Beaver. I don't have a business as I'm 18, but I want to have my own landscapeing business in a couple of years:) I had a couple of fliers around town and somebody responded to it. This is the first thing that I will be doing, and I want to do it right. Is there anything else I should know about doing a drive way?? Thanks

you wont be able to do anything with the spot that settles. dont get involved with that. Call the place with the stone you want and get a price for a tri-axle load, 15-16 yards, 20-23 tons. Then add what you want for a day or so of wheel barrow, shovel, and rake work, $250-300 labor

Edit-i missed the part about taking the old gravel out. That really doesnt make sense.

oh boy.
18 years old and your excavating out an old driveway, filling in with new stone and grading?
Are you doing this all by hand, or do you have equipment?

big daddy b: I have a Cat 246 that I can use to take the old gravel out, and put new gravel in, and grade with.
4 seasons lawn&land: thanks for the information about the settles.

It turns out the people are my next door neighbors. :laugh:

Take the old gravel and or sub base down 6" or so, then tamp it, lay out geotextile fabric, then install 4" of ASTM 57 stone (which provides much better drainage than crusher run), compact, and top off with the red stone.

The geo fabric will help prevent settling, and using mostly 57 stone will help keep the cost down... I know around here the red stone costs almost $90/CY

Thanks for the information everyone, it has helped alot. I will check with how much it costs for red rock at the rock yard tomorrow.

Do you have a dump truck or somewhere on the property to toss the old stone with the cat?

alldayjr: Theyhave a spot in their back yard where they want the old gravel, if they decide they don't want it, the Greenhouses down the road said they would take it.

Make sure you give the driveway pitch so the water can run off and compaction is key rent a large plate compactor or a vibratory roller. The soft spot can be taken care of by removing the soft soil (most Likely clay ) and then replacing with structural fill I.e. 3/4" process and compacting. And to figure out the amount of material you need the formula is length* width* depth (in feet )/27 to get cubic yards and remember that because your compacting the material you need to get more I usually use a 10% or 15% compaction factor.

jdo150: thanks for all of the information, I will remeber to compact it. (which I never though about.):laugh: Thanks for the formula too.

The problem with the previous formula is we usually install inches not feet of material this is my formula accounts for compaction

Lengh x width = area x (inches) / 240

Convert inches to feet # of (inches/12) example 4" /12=.33 feet

Also how much of a factor is that formula it is way off aztlanlc. The problem is each soil compacts more or less and you need to figure that out your formula may work for common fill but not for a process or crusher run (whatever it's called in your area). There is too much of a factor. Also to the op if they sell in tons ask for the weight of the material it's probably close to 3000lbs a cubic yard.

Not to start a discussion but lets say we have 500sqf. Area we need to fill in with 5" aggregate (my formula is for aggregate not soils) so if I use your formula this is all the math I have to do
5 / 12 = 0.416666. Then 500 x 0.416666 = 208 / 7.71 x 1.15 = 8.87 cys or 13.305 tons

I can assure you you will run short

My way. 500 x 5= 2500 / 240 = 10.41 cyd or 15.62

I'm confident and know from experience this will be exactly what I need, I have done like this for the past 8 years.

Where did you come up with the 240 just curious. I was tought my way at college and it hasn't failed me yet
