Hi Al:
I'm sure you have heard of "emulsions" - more formally known as "emulsified
asphalt" - which are a combination of liquid asphalt binder, water, and an
emulsifying agent. They are used for many purposes.
I would refer you to the Asphalt Institute publication MS-19.
A High Float Emulsion (HFE) is an asphalt emulsion that passes an additional
high float test. There are many potential grades. Again, I would refer you
to the MS-19 for more detailed information.
All Asphalt Institute publications may be ordered over the internet at:
