builds up in the crushed salt with increasing compaction slows down the creeping of the salt. Major influencing factors are the temperature (with higher temperatures accelerating the salt creeping) and the moisture of the salt, which – due to the related decrease in the resistance of the crushed salt – facilitates its compaction.

And you will spend less time compacting each layer anyway. If you do it in layers, it will be clear how much you need to lay down to get your desired depth. Show activity on this post. I looked at the gravel you are using. I would suspect you might see 1/2 to 3/4 inch of compaction…

But in terms of compaction, it is an advantage if the maximum size of the blocks does not exceed one-third of the layer thickness. This reduces the risk of rock cracks during compaction. Part-2.

4.0 FACTORS AFFECTING COMPACTION IN THE FIELD: Compaction of a particular soil is affected by following given factors – (i) COMPACTIVE EFFORT ... Smooth wheel rollers are most suitable for compacting gravels, sand and crushed rock where some crushing action is required. A speed of 3-6 kmph is considered appropriate for smooth wheel rollers. 7:

What is the compaction factor for gravel? You may ask, What type of gravel is used under concrete? Because concrete is a very porous material, it will absorb any moisture that it contacts. This can cause pooling. Without crushed stone, pooling water will settle under it and erode your slab.Adding a layer of crushed stone will add proper drainage, as well as create a barrier between your slab ...

Soil or rock from the borrow expands when dropped on the lorry or the landfill - or stockpiled. One cubic from the borrow does not translate to one cubic dump. Bulking or swell factors for some materials: Material. Density at the Borrow. 103. (kg/m3) Bulking (Swell) Factor.

Bulking factor is a ratio comparing the volume of a quantity of moist granular material to the volume of the same quantity when dry. There are many ways of classifying the soil in terms of it's ease of excavation including seismic techniques. The most common in the United Kingdom at present however is the Ease of Digging scale…

Cement Treated Crushed Rock is a mixture of natural or recycled crushed rock, fines, cement and water which is blended under controlled conditions of grading... Unspecified Crushed Rock A graded material consisting of course and fine aggregates to maximise compaction.

Compaction itself is basically the action of applying a downward force for consolidation, taking larger and smaller materials and letting them fall and work their way into place. There is a risk of over compaction as you could, especially with larger gravel, break the granules down into smaller pieces and destroying the composition of that gravel.

Compaction degree is a key factor to ensure that the mechanical properties of the crushed rock mixtures meet the requirements. So, the compaction degree should be selected as the main quality control index for the red-bed roadbed construction in practice.

@Mazura -- Seattle's major rock and topsoil vendor sells crushed rock in increments from 5 gallons to the truckload. The bulk price (for picking up material at the vendor's yard) is available in quarter of a cubic yard increments. A quarter of a cubic yard is enough to fill 10 5-gallon buckets. –

The crushed rock I was referring to, is, in my area, like a red quartzite, and it is still sorted and washed according to size and to remove fines. The larger the rock, the more reservoir capacity as far as drainage, because of more opens in the aggregate. 3/8 pea rock is the product of choice around here for AWWF footings, and 50% backfill.

It is basically a crushed blue/grey rock around 20mm in size with smaller sized rock particles right down to "fines" mixed in. This blend of sizes enables the product to be compacted down hard. So for a boggy driveway that needs stabilizing or for preparing a hard surface …

Aggregate subbase is typically composed of crushed rock, comprised of ... Excessive compaction can alter the gradation and create additional fines that may ... Accumulated water in the subbase is a key contributing factor to subbase instability and pavement distress. Thus it is important to understand how water becomes trapped in the subbase layer.

Crushed granite has a finer texture than gravel. Often called "decomposed granite," the small pieces compact more smoothly than coarse gravel, although both materials are packed the same way.
