Abstract
A system includes a geotextile material disposed over a layer of soil, a layer of aggregate disposed over the geotextile material, and a binder applied onto or over the layer of aggregate. At least some of the aggregate material is mixed with or bound together with the binder, in a top portion of the aggregate layer extending to a selected depth. The bound aggregate and binder can be substantially permeable to water flow, and configured to reduce erosion, migration or movement of the aggregate material and soil. A layer of revetment blocks can be installed over the aggregate, in order to direct water flow.
Claims20
A system comprising:
- a layer of geotextile material disposed over a layer of soil;
- a layer of aggregate material disposed over the layer of geotextile material;
- and
- a binder applied to a top portion of the layer of aggregate material;
- wherein at least some of the aggregate material in the top portion is bound together with the binder, after the layer of aggregate material is disposed over the layer of geotextile material.
A method comprising:
- disposing a layer of geotextile material over a layer of soil;
- disposing a layer of aggregate material over a top portion of the layer of geotextile material;
- applying a binder to a top portion of the layer of aggregate material, wherein at least some of the aggregate material in the top portion is bound together with the binder, after the layer of aggregate material is disposed over the layer of geotextile material.
