ITB #26-56 Attachment B http://ftp.dot.state.tx.us/pub/txdot-info/cst/TMS/100-E_series/pdfs/soi104.pdf http://ftp.dot.state.tx.us/pub/txdot-info/cst/TMS/100-E_series/pdfs/soi106.pdf http://ftp.dot.state.tx.us/pub/txdot-info/cst/TMS/100-E_series/pdfs/soi107.pdf http://ftp.dot.state.tx.us/pub/txdot-info/cst/TMS/100-E_series/pdfs/soi104.pdf otherwise shown on the plans. Ensure that each section of the embankment conforms to the detailed sections or slopes. Maintain the finished section, density, and grade until the project is accepted.

3.1. Earth Embankments. Earth embankment is mainly composed of material other than rock. Construct embankments in successive layers, evenly distributing materials in lengths suited for sprinkling and rolling.

Obtain approval to incorporate rock and broken concrete produced by the construction project in the lower layers of the embankment. Place the rock and concrete outside the limits of the completed roadbed when the size of approved rock or broken concrete exceeds the layer thickness requirements in Section 132.3.4., “Compaction Methods.” Cut and remove all exposed reinforcing steel from the broken concrete.

Move the material dumped in piles or windrows by blading or by similar methods and incorporate it into uniform layers. Featheredge or blend abutting layers of dissimilar material for at least 100 ft. to ensure there are no abrupt changes in the material. Break down clods or lumps of material.

Apply water free of industrial wastes and other objectionable matter to achieve the uniform moisture content specified for compaction.

Roll and sprinkle each embankment layer in accordance with Section 132.3.4.1., “Ordinary Compaction,” when ordinary compaction is specified. Compact the layer to the required density in accordance with Section 132.3.4.2., “Density and Moisture Control,” when density control is specified.

3.2. Rock Embankments. Rock embankment is mainly composed of rock. Construct rock embankments in successive layers for the full width of the roadway cross-section with a depth of 18 in. or less. Increase the layer depth for large rock sizes as approved. Do not exceed a depth of 2-1/2 ft. in any case. Fill voids created by the large stone matrix with smaller stones during the placement and filling operations.

Ensure the depth of the embankment layer is greater than the maximum dimension of any rock. Do not place rock greater than 2 ft. in its maximum dimension, unless otherwise approved. Construct the final layer with graded material so that the density and uniformity are in accordance with Section 132.3.4., “Compaction Methods.” Break up exposed oversized material as approved.

Roll and sprinkle each embankment layer in accordance with Section 132.3.4.1., “Ordinary Compaction,” when ordinary compaction is specified. Compact each layer to the required density in accordance with Section 132.3.4.2., “Density and Moisture Control,” when density control is specified. Proof-roll each rock layer as directed, where density testing is not possible, in accordance with Item 216, “Proof Rolling,” to ensure proper compaction.

3.3. Embankments Adjacent to Culverts and Bridges. Compact embankments adjacent to culverts and bridges in accordance with Item 400, “Excavation and Backfill for Structures.”

3.4. Compaction Methods. Begin rolling longitudinally at the sides and proceed toward the center, overlapping on successive trips by at least 1/2 the width of the roller. Begin rolling at the lower side and progress toward the high side on superelevated curves. Alternate roller trips to attain slightly different lengths. Compact embankments in accordance with Section 132.3.4.1., “Ordinary Compaction,” or Section 132.3.4.2., “Density and Moisture Control,” as shown on the plans.

3.4.1. Ordinary Compaction. Use approved rolling equipment complying with Item 210, “Rolling,” to compact each layer. Use specific equipment when required by the Engineer or as shown on the plans. Do not allow the loose depth of any layer to exceed 8 in., unless otherwise approved. Bring each layer to the moisture content directed before and during rolling operations. Compact each layer until there is no evidence of further consolidation. Maintain a level layer to ensure uniform compaction. Recompact and refinish the subgrade at no additional expense to the Department if the required stability or finish is lost for any reason.

3.4.2. Density and Moisture Control. Compact each layer to the required density using equipment complying with Item 210. Determine the maximum lift thickness based on the ability of the compacting operation and equipment to meet the required density. Do not exceed layer thickness of 16 in. loose or 12 in. compacted material unless otherwise approved. Maintain a level layer to ensure uniform compaction.

The Engineer will use Tex-114-E to determine the maximum dry density (Da) and optimum moisture content (Wopt). Meet the requirements for field density and moisture content shown in Table 2 unless otherwise shown on the plans.

Table 2 Field Density Control Requirements

Description Density Moisture Content Tex-115-E

PI ≤15 ≥98% Da – 15 <PI ≤35 ≥98% Da and ≤102% Da ≥Wopt.

PI> 35 ≥ 95%Da and ≤100% Da ≥Wopt.

Each layer is subject to testing by the Engineer for density and moisture content. Each layer must be brought to the moisture content necessary to obtain the required density and placed in a manner to ensure uniform compaction over the entire layer. The density and moisture contents for the descriptions shown in Table 2 are illustrated in the Moisture-Density Curve of Tex-114-E.

Provide the Engineer with the beginning and ending station numbers of the area completed for testing. The Engineer will determine roadway density and moisture content of completed sections in accordance with Tex-115-E, Part I. The Engineer will determine random locations for testing in accordance with Tex-115-E, Part IV. When the density is less than the required density shown in Table 2, the Engineer may perform additional testing to determine the extent of the area to correct.

Remove small areas of the layer to allow for density tests as required. Replace the removed material and recompact at no additional expense to the Department. Proof-roll in accordance with Item 216, when shown on the plans or as directed. Correct soft spots as directed.

3.5. Maintenance of Moisture and Reworking. Maintain the density and moisture content once all requirements shown in Table 2 are met. Maintain the moisture content no lower than 4% below optimum for soils with a PI greater than 15. Rework the material to obtain the specified compaction when the material loses the required stability, density, moisture, or finish. Alter the compaction methods and procedures on subsequent work to obtain specified density as directed.

3.6. Acceptance Criteria.

3.6.1. Grade Tolerances.

3.6.1.1. Staged Construction. Grade to within 1.25 in. in the cross-section and 1.25 in. in 16 ft. measured longitudinally.
