Two samples were produced by adding 4% SBS polymer to the same base binder but using different blending techniques. One sample was produced with a linear SBS, not the optimum forthe base asphalt, and it did not undergo high shear mixing. Theother binder was produced with a radial SBS polymer,optimum for the base binder and mixed in with high shear.

Production of modified bitumen

When SBS comes in contact with the bitumen, at a high temperature, the latter makes the polymer "swell" and is distributed in its inside. The interactions between bitumen and SBS take place initially, preferably involving the flexible phase of the polymer, as this represents its matrix and also due to its greater free volume.

Rheology of Polymer Modified Bitumen

performance, especially when high temperatures/low frequencies are considered. • The high temperature behaviour of SBS modified binders differs from normal penetration grade bitumen: the SBS exhibits shear thinning behaviour while the 60/70 exhibits normal Newtonian behaviour. Thus, the shear rate during mixing and compaction is very important
