Abstract
Traffic safety depends on many factors, but primarily on
the quality of the designed and constructed roads, as well
as their maintenance during the period of exploatation. In
the phase of road design and, certainly, in the period of exploatation,
one of the key elements of traffic safety is well
designed and constructed roads in accordance with the applicable
norms for road design. One of the stages of road
design that has a major impact on the quality of roads and
the degree of traffic safety is drainage.
Drainage includes several segments: (1) quick and smooth
drainage of the pavement surface from atmospheric precipitation
in order to ensure traffic on dry roads, (2) drainage of
surface waters from the surrounding basin areas that gravitate
towards the carriageway in order to prevent flooding
and/or damage to the roads under the influence of surface
waters; and (3) drainage of underground waters from the
road foundation zone in order to prevent unwanted damage
to the carriageway under the influence of underground waters.
These drainage systems, their proper design and dimensioning
according to hydrological-hydraulic calculations as
well as their maintenance in the exploitation stage are the
subject of this paper.
