Abstract


This paper deals with the use of different road vehicle combinations for abnormal transports up to gross combination mass of 120 tonnes based on the definition of the most critical vehicle combination for the assessment of load rating of bridges in Slovakia. Possibilities of using different road vehicle combinations are examined by verifying the axle loads and axle distances.
The paper analyses four different vehicle combinations to define the most critical vehicle combination which shall be used for the assessment of load rating of bridges in Slovakia for defined route.
The aim is to develop the procedure which can be used to simplify issuing of abnormal transport permission in Slovakia. In this paper are not described load models of bridges in Slovakia because of its complexity. They are described in Technical regulations TP 104 - The load rating of road bridges and footbridges.
