SBS latex is liquid SBS latex modifier that is prepared by using special technology, emulsification and using water as medium, is used for SBS modified emulsified asphalt, SBS modified asphalt, foamed SBS modified asphalt, simplifies production process, reduces equipment construction investment, saves energy and consumption, and decreases the cost greatly by comparing with solid SBS. 

1. Having good compatibility with normal emulsified asphalt and convenient use

SBS latex has completely same use method as SBR latex, improves high temperature performance of emulsified asphalt obviously by comparing with SBR latex, has good low temperature performance, and has wider application range. 

2. Using for producing modified asphalt directly, and modified asphalt production technology is simple and convenient.

Modified asphalt can be produced by using heated mixing tank, grinding and cutting aren’t necessary. Heat base asphalt to 160-165℃ and keep constant temperature, add SBS latex slowly under mixing, after finishing adding and mixing for 30 min, when there isn’t air bubble, add stabilizer to mix and develop for 2 hours. It reduces asphalt aging, and saves energy and consumption.

3. Realizing modification and foaming of asphalt at the same time when producing foamed modified asphalt. 

Use SBS latex as foaming agent, obtain asphalt foamed modified asphalt while foaming, saves energy, reduce emission, and improve road use performance of high foamed asphalt.

Performance Advantages

Improve high temperature stability, low temperature shrinkage crack resistance capacity, early strength, adhesive strength and water striping resistance of adhesive material, increase fatigue resistance of mixing material and prolong road surface.
