The National Technical Committee “CYS/TC 01 - Structural Lime” is idle since 2006, because there were no recent relevant issues for discussion. In 2014 this committee is about to merge with “CYS/TC 17 - Bituminous Concrete” which was reactivated during the year 2013. The two committees directly related and their forthcoming joint activity will provide greater flexibility and efficiency in decision-making related topics.
