Recycled Concrete Road Base Compaction Soil testing

Dec 05, 2006· But the compaction keeps coming up in the low 90's with a modified proctor, moisture looks good. The contractors seem to be laying it in there and compacting it with a vibratory roller, I'm thinking they may need a larger one. I'm just curios if there is some reason with recycled concrete that it wouldn't meet compaction.

5 Things I Learned When Grinding Concrete for the First Time

Aug 21, 2017· My recommendation when starting your first few grinding jobs is to take diamond selection very seriously. This means properly understanding bonds and segment styles, as well as testing the concrete hardness if you have the ability to. Also take into account if you are removing something on top of the concrete and what you plan to do with it after.

What is Recycled Asphalt Millings? Benefits & Cost

What is Recycled Asphalt Millings? Basically R.A.M. is old asphalt that is ground into gravel, that hardens/binds together when compacted. The best gravel to leave exposed for a long time is R.A.M (Recycled Asphalt Millings), when covered with a sprayed on application of liquid asphalt the R.A.M.will begin to bind the asphalt back together .
