Climate change is a global problem with serious social, economic and distributional effects on the environment. It is one of the main current challenges for humanity. Changing climate conditions in the long term, as well as short-term fluctuations and non-standard variation of temperature characteristics, have a significant impact on the behavior of pavement structure. Since the end of the 19th century, average temperatures have risen to 0.6 -C. The article describes the results of measurements and evaluations of ...

In addition to the traffic load, the temperature also has a significant effect on the course of stresses in cement concrete slabs. It is the load of temperature changes that is often underestimated. Recently, there have been significant changes in climatic conditions and increasingly frequent extremes (especially high temperatures in the summer months and extreme fluctuations during the day), which affect the behavior of road structures and the basic characteristics affecting the stress of cement concrete pavement...

Environmental risk factors for environmental problems with physical, chemical and biological factors that cause or may cause health disorders as well as environmental degradation. One possible factor is noise. The World Health Organization (WHO) estimates that a target of 40% of the EU population is exposed to traffic noise of more than 55 dB and that more than 30% is exposed to levels of more than 55 dB at night. The issue of protection of the health of the population against the adverse effects of noise and vibr...

In Bratislava, Capital of Slovakia, there is a huge development boom on the edge of the Old City, where is risen up a new complex down town of the city. The territory specified on the edge of the first ring called Chalupkova Centre will have around 20 high-rises with different function and there will be more than 20,000 parking spaces. At present, the operation of the territory is at the border of the saturation flows. There will be a new bus station and begins to reflect on the new tram routes. The extensive trav...

There are many technologies in road construction to ensure the better parameters of materials, mainly strength and deformation parameters and in recent years are very interesting and necessary so called environmentally acceptable technologies. With the development in the field of asphalt pavements there are various types of organic or chemical additives applied. The main reason of this application is to reduce the temperature used for producing and especially for laying of asphalt mixture. Chemical additives are s...
