Hydraulic Design Manual: Embankment Protection - Texas Department of Slope paving is a broader term that covers a variety of methods for paving slopes, including colored slope paving, exposed aggregate slope paving, and slope paving with concrete pavers. Review contractors verification of unit weight of rock-filled gabions. The concreted-rock slope protection method is used where large rock is not economically available in large quantities, yet a heavy, service type of protection is required. A geotextile is typically defined as any permeable textile material used to increase soil stability, provide erosion control or aid in drainage. Protection involves constructing a heavy mass of smaller rocks bound together by concrete. endobj When specified, ensure coloring is added to the concrete. There are three material gradation requirements based on required rock layer thicknesses. Manufacturers information can be found at: conforming to the requirements of 710-03 Vinyl Coated Steel Fence Fabric, Class A Wire Diameter, except color. At the start of gabion placement, require the contractor to verify the minimum unit weight of the gabions to ensure it meets specifications. Check to ensure that slopes and foundation areas are graded and compacted to specified tolerances. Resident engineers should be familiar with the material contained in Chapters 870, Bank ProtectionErosion Control, and 880, "Shore Protection," of the Highway Design Manual.
