Rockfill unit weight
Webthe greatest proportion by weight (Table 2.4). Where two types are thought to be equal, two components may be given (for example, sand and gravel, boulders and cobbles). BS 5930:1981 rightly noted that the properties of very coarse soils (i.e. boulders and cobbles) cannot be reliably estimated from boreholes-trial pits or exposures must be used. Web1 Sep 2009 · Mathematical formulas are given to calculate the maximum dry density (or unit weight) of the rockfill. These formulas depend on the relative amounts of soil and rocks in the total sample. If the grain size distribution curve is shallower than that for the “maximum density grading curve,” which is often the case for rockfill, then the ...
