The aim of the investigation is the analysis of strengthening systems of road surfaces situated at the weak subgrade. The paper presents three systems of strengthening of road surface using geotextiles. The results of the analysis of road surface deformation moduli values are discussed. The value of deformation modulus on the basis of measurements of vertical displacements of loaded road surface was calculated. The investigations at the proof ground of road surface was executed. Particular efficiency of the use of GEOWEB cellular mattress as strengthening of road surface was confirmed.

The article presents the design and operation of selected types of physical simulation models of the railway track subgrade and transport earthen structures. These models include: - model section of railway track for testing vertical displacements, - test bench physical simulation models of reinforced railway track subgrade, - multiscale physical simulation model of the retaining wall made of reinforced ground stabilizing the transport embankment, The paper discusses the research of the displacement state of the models constructed. The results of research can be the foundation for designing subgrade reinforcements in modernised railway tracks.

The subject of the paper is the non-cohesive medium layer with geotextiles reinforced as foundation in communication building engineering. The influence of horizontal bidirectional reinforcement on the change of value of horizontal pressure in the laboratory physical models of ground medium layer is estimated. The most important effects reinforcement have been observed, regarding increasing model load capacity.

The proposal of introducing new technologies in the engineer academic teaching for the transport infrastructure engineering run at the International University of Logistics and Transport in Wrocław since 2012 is presented. The attention was given to the two main issues: − improvement of attraction and effectiveness of professional internships, − introduction of digital tools in education of transport infrastructure engineers. The collaboration with research institutes and rail and road authorities in to order to realize master’s theses is proposed. The procedure of realization of the master’s thesis is analysed. The e-learning ideology was presented, in particular: the service system, the participants of e-learning system, authorization of participants, kinds of didactic materials and the manner of their preparation, the kinds of courses and evaluation systems (tests, analysis of tasks, and also the manner of assessment of participants activity, by means of e.g. a questionnaire). Special attention was give to didactic staff’s participation in courses on methods and techniques of distance education.

The issue of distortion and load bearing capacity of non-cohesive, monogenic and two layer soil, with vertical reinforcement, was analyzed. Separate inserts, single, double, triple and complex were used. Resistance parameters, in function of their characteristics, referring to reinforcement inserts, were evaluated. Soil base bearing capacity was calculated, on the basis of the research results of large size physical models distortion state, constructed on laboratory scale.

The authors discuss examples of solutions currently applied in the process of modernisation of main railway lines undertaken by the Polish PKP PLK S.A. in order to =assess compliance with the applicable environmental conditions. The solutions described pertain to nature conservation and restoration in the vicinity of railway routes. They are developed according to three assumptions: protection of animals along transport routes; traffic noise reduction; natural compensation which consists in restoration of the lands adjacent to railway lines in order to enhance water regimes and habitat conditions for animals.

The study presents the organization, mechanization and technology in the field of modernization and maintenance of Polish National Railway (PKP) lines, as well as in relation to the activities of the DOLKOM- Wroclaw company. Attention has been drawn to the major overhaul technology (resurfacing), the exchange of switches, surface maintenance and repair of the rail-bed (subgrade). The technological requirements, regarding the renovation and modernization of surface and rail-bed in the PKP railway network, have been discussed. In the field of rail-bed renovation, attention has been focused on the process of technological modernization of the track using a specialized multifunctional machine AHM-800R.

The construction of passenger stops of the railway transport has been proposed in order to operate the communication infrastructure of two housing complexes – the village of Mirków and the Residential Estate ‘the Four Seasons’ (Polish: ‘Cztery Pory Roku’), belonging to the agglomeration of Wroclaw. The possibility of the location of the stops within the existing infrastructure is considered. There are presented several variants of the solution to the track layout with passenger service facilities (platforms). The parameters are provided to use for the proposed railroad turnouts and the track pavement structure. In the case of the Estate ‘Four Seasons’ there are also discussed the conditions for the construction of the tram route enabling communication with the center of Wroclaw. The concept of the tram loop in terms of the location of the estate area and the geometric layout of tracks is presented as well.

Wroclaw agglomeration is presented in the structure of the national and international transport system as well as directions of development of basic transport modes in Wroclaw. The situation of intermodal transport in Poland against the background of Europe and other countries was presented. Attention was drawn to the technical and technological problems of existing intermodal transport terminals in the Wroclaw agglomeration. The economic premises of the International Logistic Centre in Wrocław and the concepts of the Centre’s construction are discussed. The PKP PLK Wroclaw Osobowice station was proposed as the location of the Logistic Centre, whose main technological element is the intermodal transport terminal.
