The article presents the stone pavement of the streets of Poznań's Chwaliszewo, a small district located between Ostrów Tumski and the Old Town. The text describes the current condition of the historic pavement and the historical constraints that have influenced its present condition. The historic surface of several streets in Chwaliszewo consists mainly of granite blocks and erratics.
The article describes stone pavements forming the surface of the Old Market Square in Poznań. In the context of postulates of replacement of a historical stone surface with modern paving, the authors took the position that the quality as well as the amount of existing rock material is fully sufficient to carry out its renovation. First and foremost, it should concern the existing granite-gneiss, and more rarely basalt, quartz and porphyry paving stones, as well as granite paving slabs and granite curb stones.
The article presents several examples of historical fragments of streets of Poznań in the so-called Upper City with preserved granite gutters, stone pavements with cube dimensions 18 X 20 cm and 10 X 20 cm. Attention was also paid to the presence of setts made of basalt basin, as well as to the roads paved with fieldstone. These increasingly rare fragments of metropolitan streets should be subject to historical and architectural protection. They should be treated as the historic fabric of every city with a long and significant tradition.
W pracy przedstawiono typowe nierówności nawierzchni dróg i ulic. Szczególną uwagę zwrócono na nierówności zdeterminowane: dziury w nawierzchni, krawężniki, koleiny, przejazdy kolejowe i tramwajowe. Przedstawiono wyniki własnych pomiarów nierówności zdeterminowanych wspomnianych typów. Będą one wykorzystane w symulacji ruchu samochodów.

The paper presents typical road and street roughness. Particular attention was paid to determined unevenness: road surface cavities, curbs, ruts, railway crossings and tramway crossings. Results of measurements are presented in graphical form. They will be apply in road vehicle motion and dynamics simulation.
