Hi all,
I´m facing the issue of trying to determine the permeability coefficient of -200mm rockfill!!?!? The gradation parameters are:
D100 = 200mm
D50 = 50mm
D10 = 7mm
This material is compacted with 16 metric tons vibratory compactors (6 passes). Does anybody have suggestions or knowledge...
The rockfill is blasted and crushed basalt. The gradation has approximately 30% passing the #4 sieve and approx. 2-3% passing the #200 sieve. The foundation will be around 2 m above the bedrock and are settlement sensitive.
The compactors are 15-19 (metric) tons so they actually compact to some...
Thanks for the input. Here are a bit more info to fill in the gap.
The water is not 2m deep. Maximum depth of around 600 mm meaning the compactor can easily operate on the layer in the water with vibration. The material that's being used is fixed and will not be altered, i.e. max size 75mm...
Hi all,
I´m looking for helpful tips or comments on the placement of rockfill (-75mm) ontop of clean bedrock, which is quite uneven (+/- 1 m or so). Due to site conditions, water is covering much of the bedrock. Draining the "pond" is not working effectively due to groundwater flow.
The...
Hi,
I have a small question with Gradation requirements. I´ve seen a few gradation requirements for roads and structural fills but I´m wondering how is the shape of these curves constructed? Obviously you want the GSD to be well graded to get a high density and, to me, the highest possible...
