Polymer Modified Binders for use in Asphalt Mixes

SAMIfalt Range of binders are used as an alternative to C170, C320, C450 or C600 bitumen in the manufacture of asphalt. SAMI Bitumen Technologies manufactures this range of binders in purpose built manufacturing plants that includes facilities for thermodynamic, mechanical and chemical modification. These binders, when incorporated in to asphalt, impart increased performance levels to the asphalt when compared to that of asphalt manufactured using standard grade bitumens.

The SAMIfalt asphalt range of binders are manufactured to Austroads Asphalt PMB grade specification and include SAMIfalt A10E, SAMIfalt A15E, SAMIfalt A20E and SAMIfalt A35P binders.

Features and benefits

SAMIfalt Range of binders offer the engineer the advantage of an aspahlt mix with vastly improved properties in terms of service and performance over conventional asphalt mixes.

These include improvements in:

• Resistance to deformation (shoving and rutting)
• Fatigue resistance
• Resistance to crack propagation (reflective cracking)
• Temperature susceptibility (improved performance in higher and lower temperature regions/extremes)
• Stripping resistance
