Bear in mind coarser soils have a lower void ratio than finer soils. So, just because you can see the voids of a large aggregate material, does not mean the void ratio is greater than a fine grained soil. Given a void ratio of 0.3 and a specific gravity of 2.7, the dry density would be: GammaD=0.7*62.4*2.7=118 pcf.

You asked, "Are compaction tests of #610 crushed stone reliable?". The answer is yes. If a proctor, either D698 or D1557, can be performed on the material then in-place density tests can be performed on it. so a method C (and possibly method B) of either D698 or D1557 can be performed.

templeton - suggest you ask your local agency who will review your grading and drainage plan for the C-values they will approve. It could be a lot more than 5%. Approved values around here vary depending on the return interval for the design storm. 10-year and 100-year storms gravel road 0.60 - 0.88 asphalt 0.75 - 0.95 (rational method)

The table is the existing grade. Each layer of cake represents one foot of fill. The area of each layer, times one foot, gives the volume of that layer. Add up the volume of each layer to get the total volume of fill. Now look at your grading plan. The existing contours are the "table", of course they are never flat.

Find out what the compaction energy required is. Usually though we only specify a compaction requirement for 3 inch minus portion (the matrix material), (ie. 75mm and less). For larger sizes then you want to specify a method spec, or a target density, or be prepared to take ring tests or something like that.

Yes, fill in the pot holes first either by grading the entire width of the drive or just fill the holes with well graded crushed stone from 3/4" to 1-1/2" in size. Lay the geotextile fabric and place 6"-8" of crushed stone base course on top of it. It can be compacted by driving the delivery trucks or the loader over it as it is placed.

Make sure the Saran wrap is loose so that the sand conforms to the particle surfaces. If the 3/4" crushed stone has sufficient fines in it, a proctor curve can be obtained. We see it used extensively on projects. Ron is correct that nuclear density testing on clean rock is inaccurate at best.

Crusher Run gravel -- also known as 'Crush and Run', 'Crush N Run', 'Graded Aggregate Base' (GAB), or 'Aggregate Base Coarse' (ABC Stone) -- has perhaps even more useful applications than it does names it goes by.

I'd recomend a 4" layer of 1 1/2" and minus crushed rock compacted and overlaid with a 2" layer of 3/4" crushed rock. If this is properly graded,compacted,and drained, you should have a good looking lane that will perform for years and years. As far as hand work, with a good blademan in the seat there shouldn't be much if any.

In construction, earthwork is the term the refers to the activities related to moving rock and soil between cut and fill areas to create the final terrain upon which buildings and road will be placed. There are different kinds of earthwork depending on whether soil is being removed to bring grade to a lower elevation or placed to raise it.

The slab will be 5"-6" thick and be reinforced to account for loads and the eventual settling of the fill below. The crushed concrete pieces are roughly golf ball to tennis ball in size and VERY VERY irregular in shape. Side wall pressures will be about the same with the angular aggregate, (crushed concrete) as with the soil.
