Quality Assurance of Construction Materials For Concrete Roads in Germany

Heavy use of the pavements caused by traffic, cli-mate and winter service requires a highly resistantconcrete with high flexural strength. Correspon-ding requirements on road concrete are laid downin «Additional Technical Instructions for Cons-tructing Concrete Pavements» (ZTV Beton), partlyalso requirements on some concrete basicmaterials.All materials used for construction of concretepavements have to meet high quality requirements.The quality assurance systemconsisting of selfcon-trolling and third part controlling has paid off fordecades in Germany. In it the production accom-panying self controlling serves at first quality as-surance and third part controlling as well asacceptance tests by the customer serve quality con-trol.
