Determine the relative oxygen absorption and volatility characteristics of asphalt using submicron thin films on a quartz crystal microbalance.
Deposited submicron-thickness asphalt films directly onto quartz crystal microbalance sensors.
Tracked high-resolution gravimetric shifts to monitor real-time oxygen uptake and volatile mass loss.
Demonstrated that quartz crystal microbalances can detect microgram-scale mass changes from oxidation and evaporation in thin asphalt coatings.
Provided qualitative differentiation between mass gain caused by oxygen absorption and mass loss resulting from volatile constituent escape.

King et al. (1969) studied this question.
