Which compactive effort to use for stabilised layer?
(OP)
Dear Sir,
I'm carrying out a stabilised layer of subbase materials(C1),the general specification states that it should be compacted at 95%,other books state that it is 97% and the revised one corresponding to the project staes that compaction shall be 98%.Please which compaction between the three is proper and correct without affecting the streght of the stabilised layer?Also what is the expected compaction of stabilised subbase materials compacted with a light hammer 2.5kg/62blows/5layer,Intermediate compaction 4.5kg/30blows/5layers and Heavy compaction 4.5kg/62blows/5layers.And which copmaction is appropriate for stabilised subbase layer C1?
Please assist.

RE: Which compactive effort to use for stabilised layer?
My first suggestion is to talk to the project geotechnical engineer. If there is no project geotechnical engineer, you should consider hiring one. Lacking that, the project specifications require 98% of some standard compaction value; that is what you should use.
