Concrete Pavements in the Czech Republic

The paper resumes the development of the concrete roads in Czechoslovakia, resp. in the Czech Republic over the span of time between two major specialized events held in Prague, in particular the XIVth World Road Congress 1971 and the 12th International Symposium on Concrete Roads in 2014. The concrete pavements are realized to motorways, high-speed roads, hardstandings and airfields. Some sections of the roadways are given as examples, illustrating the development the construction technologies underwent, including the structure of roadways and their surfacing. Special road cement is mentioned and testing methods is discussed with respect to the alkali-silica reaction in concrete and freeze-thaw resistance of concrete with the occurrence of anti-freeze salts.
