Most conventional polymers use a wet-mixing process, where the polymer is mixed through the bitumen in a high- shear mill. This ensures thorough distribution. However, some plastomeric polymers are also able to be effectively dry-mixed by controlled or manual feeding directly into the asphalt production plant.

In order to satisfactorily blend SBS polymer with bitumen, a three stage process is recommended (Shell Chemicals 1994) and includes: A predispersion step where the polymer is added to the stirred bitumen at around 180 °C. A disintegration stage to break down the polymer particles, normally with a high shear mill.

In the polymer-modified bitumen before emulsification the polymer is spread in variable droplet sizes and also contains areas of swollen polymer that has coalesced into large groups (Fig. 1(D)). This effect is consistent with that observed by Bouldin et al. (1990) and Whiteoak (1990) for incompatible polymer-modified bitumen. With the same
