Özet:

 


Polymer modified asphalts (PMA) became of great
interest over the last years because there are closely related to industrial
and constructional fields. To increase the elasticity of asphalt,
styrene-butadiene-styrene (SBS) type polymers are used which are elastomeric
block copolymers. Although the addition of SBS type block copolymers has
economic limits and can show serious technical limitations, it is probably the
most appropriate polymer for asphalt modification. The present work seeks to
identify the changes on the rheological and physical properties of SBS modified
with Dora asphalt. So it is the first study using Iraqi asphalt with styrene-butadiene-styrene.
In this paper polyphosphoric acid PPA and sulfur were used to improve the high
temperature property and storage stability of SBS modified asphalt.PPA can
improve the high temperature performance of the SBS modified Dura asphalt evidently
but declain the storage stability. Owing to the gelation of PPA, the phase
separation of SBS becomes more serious.
