Not enough testing in this
study for any conclusions
While there is probably an ideal emulsion viscosity for adequate film thickness and
infiltration into a pavement, the surface tension of the emulsion is a better indicator
of the ability of the emulsion to infiltrate the surface. Because this testing was
initiated very late in the study, there was insufficient data collected to reach
definitive conclusions about optimal surface tension. Similarly, the particle size of
the emulsion should equate with its ability to enter small pores in the pavement
surface. Emulsified rejuvenator oil particles should be easier to deform and enter
pores than higher viscosity asphalt droplets. However, only limited particle size
data was collected for this study.
