The Pavement Management System (PMS) is an important instrument for a road management, aimed at the serviceability of pavements, with an important objective - to maintain the service level with respect to road users. The experience with the implementation and application of PMS is, that it is necessary to differentiate between the use of diagnostic devices for measuring parameters of serviceability on pavements, for evaluation of road network condition, or measurements dedicated to become the inputs of the pavement rehabilitation design for a particular road section. The measuring of quality parameters on pavement is possible by means of quite a wide variety of efficient measuring devices and equipment. The criteria for the assessment of meeting needs were derived, with the priority put to a traffic safety. Comparing the evaluation of asphalt pavement condition on motorways and 1st class roads gives the results that rutting and longitudinal unevenness occur on motorways in a small proportion, only 0.5 % of the motorway length is in an emergency condition, whereas for the 1st class roads this extent is up to 1.9 % of their length. The results of theoretical designs as well as the calculations of permanent deformations on asphalt pavements became the basis for the rehabilitation planning for asphalt pavements. The asphalt pavements, based on its mechanics, can be divided into flexible and semi-rigid pavements. The depth of rutting is derived from the permanent deformation. The PMS requires a permanent development of diagnostic technology, as well as the accuracy verifications of criteria for a condition evaluation. The highest importance is given to aggregated evaluations of measured parameters. For the covering abstract see ITRD E135448.
