PPA (polyphosphoric acid) is utilized as a modifier agent of asphalt and Polymer.

In conventional asphalts is utilized to increase viscosity without reducing penetration point, increasing resistance and working temperature, achieving a higher grade of performance on the SUPERPAVE specification.

Advantages.

• Better balance between softness point and penetration point for PMA, increasing the absorption of the polymer by the asphalt;
• PPA increases adhesion and water resistance.
