for A4 Soil % compaction - hingorjo - 09-25-2010 Any one tell me about A4 soil minimum % compaction recommended by AASHTO, I think it would be 85%. m i correct or not??? kindly correct me, if you can. RE: for A4 Soil % compaction - daywalker - 09-25-2010 A4 icontains some fine grained soil patrticles but still it is considered course grained soil and vibro-roller compaction equipment should be used to compact A4 kind soils-landfiil. However, It does not matter that you have A1 or A4 soils to compact, all compacted fill should be required at least %90 or more percentange for Relative Compaction Ratio (RC). My answer is 85% is not enough value.. RE: for A4 Soil % compaction - gelbert - 09-25-2010 Dear hingorjo, AASHTO M-145: Classification of Soils and Soil Aggregates for Highway Construction Purposes Section 7.1.1 : Materials falling within groups A-1a/1b; A2, A3, A4 and A5 are satisfactory as subgrade when properly drained and compacted under moderate thickness pavement (base/ surface course) of a type suitable for the traffic to be carried or can be made satisfactory by additions of small amounts of natural fillers or binders. For Subgrade (top of embankment ) - 95% of MDD( Max. Dry Density) Subbase/Base - 100% of MDD. Surface - 100% of MDD. Hope will answer your queries.
