Our Asphalt Modifiers

Strong chemical expertise for sustainable road construction 


With comprehensive chemical, industrial and application knowledge, we develop and market ingredients and additives to increase the performance of hot, warm and cold mix asphalt. 

We offer a wide range of modifiers for asphalt performance enhancement that are all designed to improve the mechanical properties of pavements. This results in greater durability, increased driving comfort, reduced road maintenance costs and less impact on the environment. 

BASF is the world leader in the supply of styrene-butadiene rubber (SBR) for the modification of bitumen emulsions for cold mix applications.

Modifiers for Cold Mix Asphalt

Our Solution for crack sealing or slurry seals

Butonal® NS 175

✓ Improvements in conventional binder properties like increased softening point or decreased penetration

✓ In more complex rheological properties, it improves more stability and elasticity at upper use temperature range.

✓ Flexible at low service temperatures caused on polymer formulation with low Tg -53°C

Our Solution for chip seal, spray and sprinkle, or pothole repair

Butonal® NS 198

✓ The performance properties of applied binder from bitumen emulsions will be improved dramatically (vialit-pendulum-test, tension-force-test)

✓ Enhances cohesion and adhesion properties with aggregate and residue properties, e.g. forced ductility, elastic recovery and softening point.

✓ Flexible at low service temperatures caused on polymer formulation with low Tg -53°C.
