Typical applications
for PmB and special modified bitumen
∙
∙
•asphalt binder (especially for the construction class high traffic loads and asphalts for road surfaces with
particular stresses)
•SMA for very high stresses
•MA Mastic Asphalt (Bridge decks, motorways)
•porous asphalt layers (PA / ZWOPA)
•SAM / SAMI (Stress Absorbing Membrane / Stress
Absorbing Membrane Interlayer) stress-reducing layers
on damaged layers (including concrete-edification)
