Sustainable both rural and urban roads need appropriate engineering design. Behavior of pavement unbound layers and subsoil can be predicted within either standardized laboratory tests or tests in situ. The first option brings inexactness caused by sampling and test presumptions. The second one takes lot of time and money and in case of reconstruction blockades traffic which is often unacceptable mainly in urban areas. Full-scale laboratory testing can bring useful combination of both of approaches, i.e. tests are...

Bridges in urban areas often constitute architectural dominant features of particular cities. In general, while an arrangement of bridges in rural areas prefers technical points of view, in case of urban bridges esthetical or architectural perspective plays important role as well. It causes non-unified solutions and more complicated structures, frequently with very knotty details. Such structures cannot be monitored using conventional methods as shown in an example of the fallen footbridge in Prague recently. The ...
