How will I prepare the asphalt sample to stimulate the effect of moisture, on which I have to perform a AFM analysis to find the F-D plot. I am told that the equipment may be damaged if wet sample are used..?
I had planned to keep the sample under wet conditioned for 24 hours and then, plot the F-d curve. But, the operators say that the moisture might be retained in the sample which would damage the tip and are therefore fearful of conducting the test.
