Tire Rubber Modified Slurry Seal
Is a new type of cationic rubberized slurry seal that provides the durability of a conventional slurry seal along with the uniform black appearance and environmental benefits of a tire rubber modified emulsion. In addition TRMSS can be applied year round.
Save the Environment and the Pavement
Over 40 million waste tires are generated in california each year. Using TRMSS will divert approximately 80 tires per lane mile from the landfill. Your pavement preservation program is can now be your recycling program as well.
Digested Tire Rubber
TRMSS begins with a terminal blend of asphalt and tire rubber. This process combines the asphalt and tire rubber under high temperatures and pressures allowing the asphalt to digest the tire rubber completely, acquiring all the benefits of the tire rubber before it is emulsified.
More material, less money.
TRMSS used with a Type II aggregate has an application rate of 13.5 lbs/yd2, that's over 50% more aggregate per square yard than other rubberized slurry seals. When using a type I aggregate TRMSS has an application rate of 9 lbs/yd2, over 85% more aggregate per square yard than other rubberized slurry seals.

Cationic Quick Set Emulsion
TRMSS is set apart from other rubberized slurry seals because it is based upon a cationic quick set emulsion. Cationic (positively charged) emulsions cure chemically, not through evaporation like anionic (negatively charged) emulsions. This allows cationic emulsions to be used in cooler temperatures and still cure successfully. By their nature, cationic emulsions set quickly and create a natural bond to Southern California's negatively charged rock sources.

"Anionic emulsion were
first developed in the early
1900s. They found their applications
but the growth in use was
relatively slow. An
anionic emulsion does not
break chemically. The water
evaporates and causes the
emulsion to break. This is
a much slower process and
the adhesion is very poor. In the mid 1940s cationic
emulsion were introduced,
which meant a major technical
improvement. The emulsion
should be stable during storage
and transport but should break
quickly when applied. This
quality is most easily achievable
with cationic emulsions since
such emulsions react and break
chemically in contact with

The City of Thousand Oaks, Roy Allan Slurry Seal, Inc. and Paramount Petroleum were recently awarded the Excellence in Contracting award by the California Chip Seal Association for their 2010 TRMSS project. The project included both day and night work throughout the city, and recycled over 63,000 lbs of recycled tire rubber. For a short video on the project by Thousand Oaks TV click here -
