20.500.12556/DiRROS-18568 Validation of the recycled backfill material for the landslide stabilization at a railway line In mountain areas landslides many times endanger safety of transport infrastructures, and these must be stabilized with retaining wall structures. In this paper the validation of a new composite as a backfill material for landslide stabilization with a large scale demo retaining wall is presented. The new composite was made from residues of paper industry, which uses for its production deinking process. New composite was validated with the laboratory tests, construction of small demo sites and at the end with a large demo retaining wall structure with a length of 50 m. It was concluded that the paper sludge ash and the paper sludge are in proportion 70:30, compacted on the optimal water content and maximum dry density, reached sufficient uniaxial compressive and shear strength. However, the composite's hydration processes required the definition of an optimal time between the composite mixing and installation. In 2019, the retaining wall structure from the new composite was successfully built. The large demo structure is an example of the knowledge transfer from the laboratory to the construction site, in which composite and installing technology could be verified. landslides recycled backfill material paper sludge ash geotechnical composite railway line recycled material environment plazovi reciklirani material za zasipe papirniški pepel papirniški mulj geotehnični kompozit železnica reciklirani material okolje true false true Nature Publishing Group Angleški jezik Slovenski jezik © The Author(s) 2024 Neznano 2024-03-26 12:28:11 2024-03-26 12:37:30 2024-04-04 14:00:28 0000-00-00 00:00:00 2024 0 0 Nasl. z nasl. zaslona; Opis vira z dne 26. 3. 2024; str. 1-15 article no. 7031 Vol. 14 25.
