Abstract
An erosion control system is disclosed for preventing erosion of embankments including a three-dimensional material, the three-dimensional material including void volumes, and a mixture including a particulate material and a binder material included in the void volumes, wherein the binder material includes an organic binder material derived from living matter.
Claims14
An erosion control system for preventing erosion of embankments comprising a three-dimensional textile material, the three-dimensional textile material comprising void volumes, and a mixture comprising a particulate material having a particle size in a range of 0.5 to 15 mm and a binder material comprised in the void volumes,
- wherein the erosion control system has an areal weight in a range of 15 kg/m2 to 50 kg/m2,
- wherein the binder material comprises a lignin-based binder material,
- wherein the particulate material by itself or the particulate material with the binder material has a density that is higher than the density of water, and
- wherein the binder material comprised in the void volumes comprises a lignin-based binder in an amount of at least 20 wt. % and at most 80 wt. % of a bitumen-based binder, based on a total amount of binder material.
A process for manufacturing an erosion control system for preventing erosion of embankments comprising the steps of supplying a three-dimensional textile material, the three-dimensional textile material comprising void volumes, supplying a mixture comprising a particulate material having a particle size in a range of 0.5 to 15 mm and a lignin-based binder material, and introducing the mixture into the void volumes of the three-dimensional textile material to provide an erosion control system having an areal weight in a range of 15 kg/m2 to 50 kg/m2,
- wherein the particulate material by itself or the particulate material with the binder material has a density that is higher than the density of water, and
- wherein the binder material comprised in the void volumes comprises a lignin-based binder in an amount of at least 20 wt. % and at most 80 wt. % of a bitumen-based binder, based on a total amount of binder material.
