Splitt calculation - is the result correct?

Hello,

I want to order gravel (grain size 2-5mm) and am now trying to calculate the correct amount. The gravel is intended to serve as a base for lawn edging stones (24cm long, 12cm wide). With the lawn edging stones, I plan to lay a total length of 40 meters. 40 meters would be 4000 cm.

Assuming I want to make the gravel layer 5cm deep/high everywhere. Then according to my calculation:

4000 cm (total length of lawn edging stones) x 5cm (gravel layer) x 12cm (width of the stones and thus also the gravel layer). This would result in 240,000 cm3 = 2.400 m3.

At the hardware store, among other things, 1,000kg (bulk density 1,500) gravel is available for purchase. How do I know how much gravel in kg I now need or have I calculated correctly at all? Math was never my strength anyway..

Well, you have to multiply your volume by the ratio of bulk density to weight (in this case 1.5). Then you have the mass that fills your desired volume. Be careful, if you compact, you lose volume again. I think with [Splitt] you then add another 6%.

Calculate 40m x 0.12m x 0.05m = 0.24m3
On the internet, you can find approximate values for the specific weight of gravel - they vary somewhat, but let’s assume it is 1.8t/m3.

Then it should be 432kg. :)

Edit after reading ’s post: 457.92 kg

At kiesdirekt there is a calculator for this, with specific weight and compaction for many types.



I would also rather go directly to the gravel plant instead of the hardware store. You can still fit 0.4 tons on a normal trailer.
