INSTITUTE FOR TESTING AND CERTIFICATION

Bitumen testing laboratory

The bitumen testing laboratory is a part of the Accredited testing laboratory No. 1004 since 2001. Its main activity is to test bituminous binders applied both hot and cold. The laboratory acts as a reference workplace and disposes of about 50 accredited testing procedures.  Thanks to continuous improvement of the equipment and technical level of personnel, the laboratory shares many tasks of the Ministry of Transport of the Czech Republic and is considered to be a respected workplace in the highway construction department.
