Ravasol APA7 is a liquid antistrip composed of amine chemicals, designed to improve the passive adhesion between aggregate and bitumen.

It helps to grant an unbreakable binder/aggregate link during pavement service life.

Its tensioactive property modifies the bitumen polarity and enhances the chemical attraction in acid aggregates such as granite, silica, porphyry, basalt and quartzite gravel.

Improves Water Sensitivity in mixtures (EN 12697-12), Dynamic Modulus, Density, Particle Loss and Compaction ability.


RECOMMENDED DOSAGE: 0.20 to 0.75 % by weight of bitumen.
