Polyram® Cationic Quick and Slow-Setting (CQS and CSS) Bitumen Emulsifiers
Slurry Seal and Micro Surfacing
Slurry seal and micro surfacing applications are preventive pavement maintenance and pavement preservation techniques that provide an aesthetically pleasing, skid-resistant surface to restore the pavement profile and seal the underlying pavement. They protect the pavement from further deterioration and extend the life cycle of the road.
Polyram® cationic bitumen emulsifiers create slurry seal and micro surfacing applications that are longer-lasting, have better constructability characteristics and facilitate faster return to traffic. The Polyram® line of cationic emulsifiers for micro surfacing and slurry seal goes beyond typical specifications to deliver the following performance advantages:
- Strong adhesion properties that result in less early construction and long-term raveling or aggregate loss.
- Increased mixing time with hot pavement and hot aggregate, allowing for paving in hot conditions without struggle.
- Easy control of chemical break allowing for fast traffic return times when paving in cooler conditions and at night.
Polyram® cationic emulsifiers are compatible with all asphalt / bitumen types, including paraffinic and those modified with styrene-butadiene-styrene (SBS), styrene-butadiene rubber (SBR)and natural latexes. They can be formulated to perform with both reactive and unreactive aggregates of various types including granite, diabase, basalt, chert, limestone and sandstone.
Grave Emulsion
Grave emulsion is a coating technique wherein coarse aggregates are coated to a greater or lesser degree in a binder-rich mastic. In construction, the grave emulsion is used as a base course and a binder course for low to medium traffic. It can be laid using a finisher or a grader. In this case, the aggregate emulsion can be used for reprofiling, reshaping and widening.
When a grave emulsion is formulated with Polyram® cationic bitumen emulsifiers, it provides the aggregate with greater cohesion which it naturally lacks without a binder to create a longer-lasting road.
Storable Cold Mix
Storable open-graded cold mix is used in road maintenance to patch potholes and similar localized damage from weathering and traffic. When manufacturing cold mix, aggregates are often mixed with a bituminous emulsion. Bitumen emulsions formulated with Polyram® cationic bitumen emulsifiers are especially effective in producing cold mixes that can be stored for several weeks.
