Asphalt Density Testing using ASTM D2922

[cwarf]

We recently had some asphalt installed and tested the density by ASTM D2922 (Nuclear Method). The sampling occurred while it was raining and the asphalt surface was wet. I was wondering if the surface water had any impact on the density results. Our results did not meet our spec.

Not likely. Why not retest it dry? Would be a good idea to correlate with cores anyway.

Was it wet when the asphalt was placed? If so this is why it failed!
