Emulsified
asphalt
Emulsified
asphalt is an energy-saving environment-friendly material
for road construction. FRIPP has developed two kinds of
asphalt emulsifiers, anion type and cation type.
Emulsified asphalt produced with cation type emulsifier
can mix well with aggregates and fits for road pavement,
maintenance, and slurry seal coat. The technology was
commercialized in Guangzhou Petrochemical Company in 1993
and the produced asphalt was used in road construction in
Heyuan Guangdong, Dandong Liaoning, and etc.
FRIPP
developed two kinds of anion type emulsifier, L-1 and L-2.
The former, used for producing slow-cracking emulsified
asphalt in slurry seal coat and for agitation
construction, has been applied in Liaoning, Hebei and
other places with good results. The latter is for
producing fast-cracking emulsified asphalt and rubber
modified asphalt, whose application in Fushun Asphalt Felt
Factory showed that using L-10 to produce waterproof
material has strengths such as energy saving, no
pollution, easy operation and long durability. The asphalt
latex, produced with L-10, was granted Chinese patent in
1994.
