273 - Geocell System Retaining Wall

273.00_06_us_09_24_2009

Description

273.01 This work consists of constructing a geocell system retaining wall using a cellular confinement system such as Presto Geoweb Cellular Confinement System or approved equal, in accordance with the plans and manufacturer’s recommendations. Furnish the CO with product literature, certification, and product sample as required in Section 106.03 for review and approval 14 days prior to product purchasing.

Materials

273.02 Requirements. Ensure that material conforms to specifications in the following subsections:

Granular Backfill Type (a) 703.03

Geotextile, Type II (A, B, C) 714.01

Geocell, 8”x8’x21’ nominal dimensions 736

Construction Requirements

273.03 General. Perform the work specified in Section 209. Use ditches, grading or similar approved methods to prevent surface runoff that may occur during inclement weather from ponding in the foundation excavation.

273.04 Storage and Handling of Material. During shipment and storage, wrap geotextile materials in heavy-duty protective covering per manufacturer’s recommendations. Protect the material from mud, soil, dust, debris, damage and sunlight exposure prior to installation.

273.05 Geotextile Installation. Where required, place the geotextile according to Section 207. The surface shall be approved in writing by the CO prior to placing geotextile.

Sew or overlap adjacent strips a minimum of 12” at joints. Insert securing pins through both strips of overlapped geotextile at minimum intervals of 3 feet, but no closer than 2 inches to each edge, to prevent the geotextile from being displaced.

The installed geotextile shall be approved in writing by the CO prior to setting the geocells.

273.06 Geocell Installation. Place the geocell sections directly on the prepared and approved subgrade.

Expand the geocell sections into position at the grades and lines as shown on the plans and per the manufactures recommendations for installation. Secure the expanded geocell sections with suitable “stretcher frames”, steel stakes driven inside selected outer cell walls, or other similar methods as allowed by the manufacturer prior to filling. Ensure that the individual cells have expanded to the minimum dimensions required by the manufacturer. If necessary field cut sections as per the manufacturer’s recommendations to the lines shown on the plans.

Connect geocell panels in accordance with the manufacturer’s recommendations.

273.07 Infill Placement. Furnish the CO with the manufacturer’s specific recommendations for backfilling 14 days prior to placement of the geocells.

Place coarse granular backfill meeting Subsection 703.03, AASTHO M43, Size 7 (3/8” clean pea gravel) into the expanded cells with equipment appropriate for the site conditions such as a backhoe, front-end loader or other equipment approved to place the material. Do not drop infill material more than 3 feet to avoid damage or displacement of the cell walls. Fill and compact the outer cell with topsoil to aid in the establishment of vegetative new growth on wall face.

Overfill the geocell cells and level to a minimum of 2 inches above the top of the cell walls. Approved equipment may be used to place the infill provided that it only traffics above geocell sections that have been filled and covered with the minimum 2 inches of additional material. Consolidate the infill material with a vibratory plate compacter. Operate compaction equipment over the full width of the geocell. Make at least three complete passes or until visible deformation of the infill ceases. Grade the surface to be even with the top of the cells prior to the placement of a subsequent layer of geocell. Following the installation of the last (top) layer of geocell material, ensure that the cell walls are not exposed after final grading is completed.

If the CO determines the geocell manufacturer’s specific recommendations for backfilling are more stringent than stated above then the manufacturer’s backfilling recommendations will be used.

273.08 Acceptance. Geotextile will be evaluated under Subsections 106.02 and 714.01.

Material for geocell will be evaluated under Subsections 106.2 and 106.03.

Granular backfill material will be evaluated under Section 106.02 and 106.04.

The cost for furnishing and placing geotextile for the geocell installation is incidental to this pay item and no separate payment will be made.

322 - Minor Aggregate Courses

322.00_nat_us_10_24_2007

322.01 This work consists of constructing one or more courses of aggregate on a prepared surface. Work includes producing aggregate by grid rolling, screening, or crushing methods, or placing pit-run or Government-furnished aggregate.

Surface aggregate grading is designated as shown in Table 703-3.

Subbase and base aggregate grading is designated as shown in Table 703-2.

Screened aggregate grading is designated as shown in Table 703-16.

Material

322.02 Conform to the following Subsections:

Aggregate 703.05

Water 725.01

Construction Requirements

322.03 General. Prepare the surface on which the aggregate course is placed according to Section 204 or 303 as applicable.

Request approval of the roadbed in writing before placing aggregate.

Develop, haul, and apply water in accordance to Section 170.

Submit target values within the gradation ranges shown in Table 703-2 or 703-3 for the required grading. After reviewing the proposed target values the CO will determine the final values for the gradation and notify the

Contractor in writing.

No quality requirements or gradation other than maximum size will be required for pit run and grid-rolled material. For grid rolling, use all suitable material that can be reduced to maximum size.

After processing on the road, remove all oversize material from the road and dispose of it as directed by the CO.

If the aggregate is produced and stockpiled before placement, handle and stockpiled according to Section 320.

Establish stockpile sites at approved locations.

322.04 Mixing and Spreading. Mix the aggregate and adjust the moisture content to obtain a uniform mixture with a moisture content suitable for the specified compaction method. Spread and shape the mixture on the prepared surface in a uniform layer with no segregation of size, and to a loose depth that will provide the required compacted thickness.

Do not place in layers exceeding 6 inches in compacted thickness for aggregate base and surface courses or twice the maximum particle size for screened aggregate. When more than one layer is necessary, compact each layer according to Subsection 322.05 before placing the next layer. Route hauling and leveling equipment uniformly over the full width.

When placing aggregate over geotextile, place aggregate in a single lift to the full depth specified.

322.05 Compacting. Compact each layer full width. Roll from the sides to the center, parallel to the centerline of the road. Along curbs, headers, walls, and all places not accessible to the roller, compact the material with approved tampers or compactors.

Compact the aggregate using one of the following methods as specified:

Compaction A. Operating spreading and hauling equipment over the full width of the travelway.

Compaction B. Operate rollers and compact as specified in Subsection 204.11(a)(1).

Compaction C. Moisten or dry the aggregate to a uniform moisture content between 5 and 7 percent based on total dry weight of the mixture. Operate rollers and compact as specified in Subsection

204.11(a)(1).

Compaction D. Compact to a density of at least 95 percent of the maximum density, as determined by

AASHTO T 99, method C or D.

Compaction E. Compact to a density of at least 96 percent of the maximum density, as determined by the Modified Marshall Hammer Compaction Method (available upon request from USDA Forest

Service, Regional Materials Engineering Center, P.O. Box 7669, Missoula, MT 59807).

Compaction F. Compact to a density of at least 95 per-cent of the maximum density, as determined by

AASHTO T 180, method C or D.

Compaction G. Compact to a density of at least 100 percent of the maximum density as determined by the Modified Marshall Hammer Compaction Method (available upon request from USDA Forest

Service, Regional Materials Engineering Center, P.O. Box 7669, Missoula, MT 59807).

For all compaction methods, blade the surface of each layer during the compaction operations to remove irregularities and produce a smooth, even surface. When a density requirement is specified, determine the in place density and moisture content according to AASHTO T 310 or other approved test procedures.

322.06 Construction Tolerance. If grade finishing stakes are required, finish the surface to within ±0.10 feet from staked line and grade elevation.

If grade finishing stakes are not required, shape the surface to the required template and check the surface with a

10-foot straightedge. Defective areas are surface deviations in excess of 1/2 inch in 10 feet between any two contacts of the straightedge with the surface.

Correct all defective areas by loosening the material, adding or removing material, reshaping, and compacting.

Ensure that the compacted thickness is not consistently above or below the specified thickness. The maximum variation from the compacted specified thickness is ½ inch.

Ensure that the compacted width is not consistently above the specified width. The maximum variation from the specified width will not exceed +12 inches at any point.

322.07 Maintenance. Maintain the aggregate course to the correct line, grade, and cross-section by blading, watering, rolling, or any combination thereof until placement of the next course. Correct all defects according to

Subsection 322.06.

322.08 Acceptance. See Table 322-1 or Table 322-2 as applicable, for sampling and testing requirements.

Aggregate gradation and surface course plasticity index will be evaluated under Subsection 106.04. If the aggregate is obtained from a Government stockpile then the above characteristics will be evaluated under

Subsection 106.02. Other aggregate quality properties will be evaluated under Subsections 106.02 and 106.04.

Placement of aggregate courses will be evaluated under Subsections 106.02 and 106.04.

The allowable upper and lower aggregate gradation limits are the Target Value plus or minus the allowable deviations shown in Tables 703-2 and 703-3.

The allowable upper and lower Plasticity index limits for surface courses are stated in 703.05(b).

Preparation of the surface on which the aggregate course is placed will be evaluated under Section 204 or 303 as applicable.

322.09 Measure the Section 322 items listed in the bid schedule according to Subsection 109.02 and the following as applicable.

Measure square yard width horizontally to include the top of aggregate width including designed widening.

Measure the square yard length horizontally along the centerline of the roadway.

If the measurement for aggregate is by cubic yard using contract quantities then measure aggregate by the cubic yard in-place once compacted, otherwise measurement for aggregate by the cubic yard is measured by the cubic yard in the hauling vehicle.

Measure thickness perpendicular to the grade of the travelway.

Measure width perpendicular to the centerline.

322.10 The accepted quantities will be paid at the contract price per unit of measurement for the Section 322 pay items listed in the bid schedule. Payment will be full compensation for the work prescribed in this Section. See

Crack seal and fill only when internal pavement temperatures are between 36 and 68 °F the road surface is dry, there is no frost in the road section, and the weather is not foggy or rainy.

Heat, mix, and apply the crack sealing and filling materials as recommended by the sealant manufacturer.

Submit a copy of the manufacture’s recommendations to the CO prior to the start of work.

Prepare cracks between 1/4 inch and 1 inch and apply sealant by one of the following methods:

Crack Sealing - Rout and clean all cracks between 1/4 inch and 1 inch wide. Rout cracks to produce a reservoir with straight ½ inch vertical walls and a 1 1/2 inch wide flat bottom. Use a low-modulus rubberized asphalt. Completely fill the routed cross section flush with the pavement surface.

Crack Filling - Clean the crack between 1/4 inch and 1 inch wide. Prepare cracks to a depth of at least three times the crack width. Ensure crack sealing materials penetrates more than twice the crack width.

For cracks between 1/2 inch and 1 inch where sealant penetrates more than two times the crack width, use a backer rod.

For cracks with a width greater than or equal to 1 inch, clean and fill flush to the existing surface with asphalt mix according to Section 401, 402, 403, 404, or 417.

For cracks less than ¼ inch wide, clean and fill with CSS-1, SS-1, or joint sealant. Apply a sealant band less than 2 inches over the crack, such that the crack is centered under the band. Submit a copy of, and adhere to, the manufacture’s recommendations for heating and applying the joint sealant.

Clean cracks with a stream of air to remove all dirt, dust, or deleterious matter adhering to the crack walls or remaining in the crack cavity so that the crack is clean and dry when the sealant is applied. Blow or brush dry material off the pavement surface. Avoid damage to the adjacent pavement.

Use approved methods to protect all seal materials from being picked up by traffic. Treat seal material tracked onto the road surface as directed by the CO.
