Compaction Wet clay
Compaction Wet clay
(OP)
Hi to all, this is my first post.
Building an embankment, 3m avg height for a future motorway, with Stoney clay, with borderline levels of moisture. Would laying a starter layer of 200m of pebble-like material help dry the clay faster, and so achieve better CBR values?
Thanks

Likewise, after rain, compacting of the upper less moist material will bring moisture up also.
So using a starter layer of material less susceptible to moisture is a good idea.

I cannot stockpile because if I do it I run the risk of getting the material wetter if it rains (very often here).
The idea is first not to get moisture from the ground up into the first layers of embankment when we compact. Also what iandig says. So if I have a 8 meter embankment I am thinking of using a sandwich layer halfway up.
The ones we have done without this layer are giving us rutting problems in localised points. I want to avoid using lime...
We started today, I will tell you if it works..
