Abstract
Within The Pavement Management System, transversal roughness - the rut depth of pavement
surfaces is one of the indicators for assessing the condition of the roads which determines their driving
performance. Since the rut collects and retains water (instead drainage), the depth or amount of
retained water on the pavement surface has a crucial influence on the creation of aquaplaning and
disorder of traffic safety.
The measurements of roughness were made on the motorway A-4 that passes though Republic
of Macedonia which is part of the international road E-65 (length 14,2 km) with the measuring
apparatus high-speed inertial profiler (The Dynatest Road Surface Profilometer). The evaluation of the
condition of the pavement surface in terms of transversal roughness – rut depth was conducted by
Slovenian criteria for rut depth (TSC 06.610:2003).
The results from the evaluation of the measurements showed that the pavement surface is
heterogeneous represented in all three states: good, satisfactory and poor, which means that certain
sections of the motorway require repairmen of pavement surface.
Rut depths and possibility of creating aquaplaning are in proportional dependence; the greater
the rut depth, the greater the amount of water that is retained in them, because the amount of water on
the pavement surface is creating conditions for the appearance of aquaplaning. Measures for reducing
the risk of aquaplaning are: regular measurement and evaluation of the condition of transversal
roughness, taking measures for their rehabilitation, improvement of drainage capability of pavement
surfaces and improved coefficient of resistance against sliding.
