AASHTO T99

[malidar1]

I have aquestion that we correct max dry density vs. moisture content curve for +4 material in ASTM D698-what is in AASHTO T-99? Do we also correct the curve in AASHTO T99 or not. I have seen a curve without correction even though the material had coarser fraction.

I haven't looked at T99 in a while, but it has always tracked D698. Find a recent copy of T99 and compare, but you'll likely find they are essentially the same.
