ITEM 421 MICROSURFACING
421.01 Description. This work consists of constructing a cold laid polymer
modified emulsified asphalt pavement course to fill ruts or provide a leveling
and/or surface course for existing pavements. The paving mixture is composed of
a polymer modified emulsified asphalt binder, crushed aggregate, mineral filler,
water, and other additives.
421.02 Materials. Use a polymer modified emulsified asphalt binder (Binder)
consisting of the following materials milled together:
A. One hundred percent natural latex modifier or a synthetic latex modifier
conforming to 702.14.
B. CSS-1h emulsified asphalt conforming to 702.04, except the cement-mixing
test is waived.
C. Other emulsifiers.
Ensure that the Binder has a minimum of 3 percent solids based on the weight
of the asphalt binder content of the Binder. Do not use port addition of the
polymer to the emulsified asphalt.
