Sealoflex® PMB for heavy duty asphalt

Climate changes, higher traffic volumes, heavier wheel loads. Today, many different factors limit the durability of asphalt pavements. The Sealoflex® SFB5 range of polymer modified binders has been specially designed to cope with such extreme loading cases. Sealoflex® SFB5 binders provide quality and durability unrivalled by any other kind of asphalt binder.

Sealoflex® SFB5 is an SBS polymer modified binder with relatively high polymer content. With the specially developed Sealoflex® processing technique the polymer is cross-linked and stabilised. Sealoflex® SFB5 binders have premium properties with respect to:

  • Temperature susceptibility
  • Elasticity and resistance to deformation
  • Ductility and resistance to fatigue
  • Ageing
  • Adhesion promotion

Accordingly asphalt mixtures with Sealoflex® SFB5 are rut resistant, crack resistant and almost impossible to fatigue even in extreme load cases which is confirmed by results in laboratories and in practice.
