  Broad absorption lines seen in some quasars prove the existence of ionized
plasma outflows from the accretion disk. Outflows together with powerful jets
are important feedback processes. Understanding physics behind BAL outflows
might be a key to comprehend Galaxy Evolution as a whole. First radio-loud BAL
quasar was discovered in 1997 and this discovery has opened new possibilities
for studies of the BAL phenomena, this time on the basis of radio emission.
However, information about the radio structures, orientation and age of BAL
quasars is still very limited due to weak radio emission and small sizes of
these objects. Our high-resolution radio survey of a sample of BAL quasars aims
to increase our knowledge about these objects. In this article, we present some
conclusions arising from our research.
