摘　　要：On 16 July 2021,the German“Mantelverordnung”(Construction Materials Regulation)was published in the Federal Law Journal.From August 1,2023,this regulation is to be applied nationwide and,for the first time,regulates legally nationwide binding requirements for mineral construction waste and its use in technical structures.It also refers to specific construction methods with construction waste material.In the course of the construction of infrastructure traffic routes,it is possible to use these construction materials with limited contamination for the construction of,e.g.,noise barriers,dams or embankments.The German M TS E(Merkblattüber Bauweisen für Technische Sicherungsmaßnahmen beim Einsatz von Böden und Baustoffen mit umweltrelevanten Inhaltsstoffen im Erdbau)Guideline of the FGSV(Road and Transportation Research Association)lists various alternatives for barriers in such structures.Geosynthetic barriers,e.g.,GCLs(Geosynthetic Clay Liners,also known as bentonite mats)or polymeric geomembranes as well as other geosynthetics can have economic and design advantages over conventional mineral barriers.Depending on the proposed construction method,the guideline sets out certain requirements,not only but also for permittivity and confining stress.In the following,the construction methods in general and the design solutions with GCLs in particular are presented.
