    Abstract

    Geosynthetic clay liners (GCLs) are used in numerous applications from earth-work-related projects such as ponds and landfills to concrete-related work such as waterproofing applications. Multi-component GCLs have been used extensively in the past two decades; however, some multi-component GCLs should be used only in specific applications and should not be used in earth-work-related projects where abrasion-type damages might occur. Two types of multi-component GCLs were used in various shear box tests to help simulate potential abrasion-type damages that might occur in field projects. A polypropylene-coated GCL and a polyethylene-laminated geofilm GCL were subjected to various subgrade conditions to determine whether damage occurred. However, it should be said that multi-component GCLs are made and offered to eliminate some unknown factors on projects such as a lack of subgrade information provided prior to deployment start up, and thus there is a need for them.
