Reclaimed Asphalt Compaction
Reclaimed Asphalt Compaction
(OP)
We will be using reclaimed/recycled asphalt base in a parking lot. The question was asked if ASTM D698 would be appropriate for testing the compaction. If not, can someone tell what the appropriate specification would be?
Thanks in advance.
Thanks in advance.

Also, determining the actual moisture content of milled asphalt is a bit tricky. You can use a nuclear moisture gage or a Speedy Moisture Meter (calcium carbide type), but both should be correlated to a laboratory method...that's where there's a problem. Oven drying doesn't work well with asphalt materials, even weathered ones. It drives off volatiles and gives an erroneously high moisture content.
Use one of the asphalt material moisture determination methods, but typical testing labs don't have the equipment or the expertise to do these tests. Hopefully your local lab can do them or can work through an equivalence by doing several extractions to determine the asphalt content and then applying a correction after drying.
