Abstract
Some results from tests carried out on the first in Poland continuous slab railroad viaduct made of post-tensioned prestressed concrete subjected to static, dynamic and service loads are presented. The spans are characterized by an atypical static scheme and the use of a new then constructional material, i.e. post-tensioned prestressed concrete. The tests on the prototype spans were carried out after 25 years of use in order to evaluate their usability and service life. The obtained results were analyzed and conclusions concerning the possibilities of the common use of these spans in railroad bridges and for running trains with increased axle loads (250 kN) and speeds (140-200 km/h) were drawn.
