Section 202 - Removal of Structures & Obstructions

Description

202.01 Work. Salvage, remove, and/or dispose of buildings, fences, structures, pavements, culverts, utilities, curbs, sidewalks, and other obstructions as SHOWN ON THE DRAWINGS.

Salvage designated materials and backfill the resulting trenches, holes, pits, or as SHOWN ON

THE DRAWINGS.

Construction

202.02 Salvaging Material. Use reasonable care to salvage all material designated to be salvaged. Salvage in readily transportable sections or pieces. Replace or repair all members, pins, nuts, plates, and related hardware damaged, lost, or destroyed during the salvage operations.

Wire all loose parts to adjacent members or pack them in sturdy boxes with the contents clearly marked.

Carefully remove culvert, taking precautions to avoid damage. Store culverts to be relaid, when necessary, to prevent loss or damage before relaying. Replace without additional compensation all sections lost from storage or damaged by use of improper methods.

Matchmark members of salvaged structures. Furnish the CO with one set of drawings identifying the members and their respective matchmarks.

Stockpile salvaged material in a designated area.

202.03 Removing Material. Saw cut sidewalks, curbs, pavements, and structures when partial removal is required.

Raze and remove all buildings, foundations, pavements, sidewalks, curbs, fences, structures, and other obstructions that interfere with the work and are not designated to remain.

Existing culverts may be left in an embankment, provided that no portion of the culvert is within 2 feet of the subgrade, the embankment slope, or a new culvert or structure. Crush culvert ends.

Remove structures and obstructions in the roadbed to 12 inches below subgrade elevation.

Remove structures and obstructions outside the roadbed to 12 inches below finished ground or to the natural stream bottom.

Prior to removal, place rock and soil material located on the bridge deck, or structure so that it does not enter a stream.

Remove the substructures of existing structures down to the natural stream bottom, and remove the parts outside of a stream down to at least 12 inches below natural ground surface or finished groundline, whichever is lower. Remove portions of existing structures that lie wholly or in part within the limits for a new structure to accommodate construction of the proposed structure.

Except in excavation areas, fill cavities left by structure removal with material to the level of the finished ground, and compact. Place and compact the type of backfill material that is SHOWN ON THE DRAWINGS, designated in the SPECIAL PROJECT SPECIFICATIONS, or approved by the CO.

202.04 Disposing of Material or Structures Not Designated for Salvage.

Dispose of material and structures as SHOWN ON THE DRAWINGS or designated in the SPECIAL PROJECT SPECIFICATIONS, using one or more of the following methods:

(a) Removal From Project. Make necessary arrangements with property owners, and haul debris to suitable disposal locations as approved by the CO. Furnish a signed copy of the disposal agreement. Hazardous materials must be properly disposed of.

(b) Burning. Burn debris using high-intensity burning processes that produce few emissions.

Examples include incinerating, high stacking, or pit and ditch burning. Provide a watchperson during burning operations.

When burning is complete, extinguish the fire so no smoldering debris remains. Dispose of unburned material in accordance with Subsection 202.04(c).

(c) Burying. Bury debris in trenches or pits in approved areas within the right-of-way. Do not bury debris inside the roadway prism limits, beneath drainage ditches, or in any riparian areas.

Place debris with earth material in alternating layers consisting of 3 feet of debris covered by 2 feet of earth. Distribute stumps, logs, and other large pieces to form a compact mass and minimize air voids. Fill all voids. Cover the top layer of buried debris with at least 12 inches of compacted earth. Grade and shape the area.

Section 602

Section 602 - Minor Concrete Structures

602.01 Work. Construct reinforced or unreinforced minor concrete structures.

Materials

602.02 Requirements. Furnish materials that meet the requirements specified in the following subsections:

Air-Entraining Admixtures .........................................................711.02 Cement ........................................................................................701.01 Chemical Admixtures .................................................................711.03 Coarse Aggregate for Portland Cement Concrete .......................703.02 Curing Material ...........................................................................711.01 Fine Aggregate for Portland Cement Concrete ...........................703.01 Fly Ash ........................................................................................725.04 High-Strength Nonshrink Grout .................................................701.02 Latex Modifier ............................................................................711.04 Reinforcing Steel ........................................................................709.01 Water ...........................................................................................725.01

602.03 Concrete Composition. Use the concrete composition method DESIGNATED IN THE

SCHEDULE OF ITEMS.

(a) Method A. Furnish to the CO a mix design showing the proposed weights of aggregate, water, and cement per cubic yard of concrete a minimum of 7 days prior to beginning placement.

Proportion the cement, aggregate, and water to obtain concrete with good workability. Ensure that slump is 4 inches or less, as determined by AASHTO T 119. Ensure that air-entrainment is 6 ± 1 percent, as determined by AASHTO T 152 or T 196.

Ensure that the concrete develops a 28-day minimum compressive strength of 3,000 psi, unless otherwise SHOWN ON THE DRAWINGS. Furnish concrete for specimens. Strength will be determined by test cylinders made and cured in accordance with AASHTO T 23 and tested in accordance with AASHTO T 22.

Failure of any test cylinder to meet the required strength, for any structural element tested, will be considered evidence of noncompliance with the strength requirement of this specification.

(b) Method B. Submit for approval the following information a minimum of 7 days prior to beginning placement:

(1) Type, grading, and sources of aggregate.

(2) Type and source of cement, blended cement, or fly ash.

(3) Saturated surface dry weights of the fine and coarse aggregate in pounds per cubic yard of concrete.

(4) Weight of mixing water in pounds per cubic yard of concrete.

(5) Weight of cement in pounds per cubic yard of concrete.

(6) Admixture type, quantity, and certification by manufacturer.

(7) Air content.

(8) Slump.

(9) 28-day compressive strength.

Ensure that the concrete contains not less than 611 pounds per cubic yard. Ensure that slump is 4 inches or less, as determined by AASHTO T 119.

When a commercial supplier is used, furnish a certification with each truckload of concrete certifying that the material and mix proportions used are in conformance with the approved mixture.

(c) Method C. Make the concrete using a dry, preproportioned, blended, and bagged mix meeting the requirements of ASTM C 387 and mixed at the jobsite in accordance with the manufacturer’s recommendations.

(d) Fly Ash- or Pozzolan-Modified Concrete. Fly ash may be substituted for cement at the rate of 1.2 pounds of fly ash per 1.0 pound of Portland cement. After substitution, reduce the design aggregate volumes by an amount equal to the net increase in volume of the combined cement and fly ash. Replace no less than 10 percent and no more than 20 percent of the weight of Portland cement required with fly ash at the above rate. For purposes of controlling the maximum water/cement ratio of 0.49, make the water/cement ratio for fly-ash-modified concrete the ratio of the weight of water to the combined weights of Portland cement and 60 percent of the weight of the fly ash.

Extend the standard 28-day curing period for compressive-strength tests for fly-ash modified concrete by 1 day (rounded to the nearest whole day) for each 1.5 percent of Portland cement replaced with fly ash at the selected rate. (Example: If the maximum of 20 percent cement is replaced, the curing period for cylinders is 41 days.)

Construction

602.04 Forms. Design and construct forms so they can be removed without damaging the concrete. Make them free of bulge and warp, and constructed so that the finished concrete has the form and dimensions SHOWN ON THE DRAWINGS and is true to line and grade. Concrete may be placed without forms where SHOWN ON THE DRAWINGS.

Design forms for concrete that contains a retarding admixture, fly ash, or other pozzolan replacement for cement so that the lateral pressures exerted by the full anticipated height of fluidized concrete are contained, unless documented information in regard to initial set is provided by the manufacturer.

602.05 Placing Concrete. Place all reinforcing steel in position as SHOWN ON THE DRAWINGS, and ensure that it is securely held in place by approved supports during placing of concrete. Do not place concrete until the grading, forms, and steel reinforcements have been inspected and approved by the CO. Give the CO 24 hours written notice prior to placement of any concrete.

Ensure that reinforcing steel material and construction requirements are in accordance with Section 554.

Discharge all concrete prepared using methods A and B into the forms within the time limits shown in Table 602-1. These time limits are based on jobsite ambient air temperature, cement type, and admixture used. Begin counting time from when the cement is introduced into the aggregate. Discharge concrete prepared using method C into the forms within 1-1/2 hours after introducing water to the mixture. Do not retemper concrete. Cement must be added to the mixer at the jobsite when required in the SPECIAL PROJECT SPECIFICATIONS. Do not mix or place concrete when the daily minimum atmospheric temperature is, or is expected to be, less than 40 °F unless adequate provisions are made to protect the concrete.

Place concrete to avoid segregation. Use high-frequency internal vibrators for consolidating concrete in the forms. Operate vibrators to produce concrete free of voids, but do not hold them in one place long enough to result in segregation or formation of laitance on the surface.

Method C concrete may be rodded instead of internally vibrated as necessary to remove voids.

Do not use aluminum pipe, conduit, or troughs for transporting concrete. When concrete is pumped, take samples from the discharge stream at the point of placement.

602.06 Finishing. Perform finishing of concrete surfaces as follows:

(a) Formed Surfaces. Unless otherwise SHOWN ON THE DRAWINGS, remove all fins and irregular projections exceeding ¼ inch from the exposed surfaces. Fill holes produced by removing form ties with dry-pack mortar or other approved patching compounds.

(b) Unformed Surfaces. Strike off unformed surfaces with a straightedge, and finish them to a smooth uniform texture by floating and troweling. Prepare final finish of the surface as SHOWN

ON THE DRAWINGS.

Table 602-1. - Concrete discharge time limits.

Cement Type With and Without Admixtures

Time limit (hour) < 86 oFa ≥ 86 oFa

Type I, IA, II, or IIA 2.0 1.5 Type I, IA, II, or IIA with water reducing or retarding admixture 3.0 2.0

Type III 1.5 1.0 Type III with water reducing or retarding admixture 2.0 1.5

a. Ambient air temperature.

602.07 Curing Concrete. Beginning immediately after finishing, cure all concrete a minimum of 7 days or, if high-early-strength cement is used, a minimum of 3 days. For fly-ash-modified concrete placed in structures, the required moisture-controlled curing period shall be:

Percentage of Cement Replaced by Weight

Required Curing Period

10% 9 days 11–15% 10 days 16–20% 11 days

For cold weather concreting, maintain a controlled temperature for the required curing period.

The above requirement for an extended curing period may be waived if a compressive strength of 65 percent of the specified 28-day design strength is achieved in 6 days.

Cure by maintaining a minimum concrete temperature of 40 °F and keeping the concrete continuously moist. Keep moist by supplying additional moisture or preventing moisture loss.

Acceptable methods of supplying additional moisture are ponding or sprinkling, and covering with burlap cloth that is kept saturated. Surfaces SHOWN ON THE DRAWINGS may be covered with saturated sand or 6 inches of saturated hay or straw to retain moisture.

Acceptable methods of preventing moisture loss are applying liquid membrane forming compounds, or waterproof paper or polyethylene sheet materials. Apply liquid membrane forming compounds by spraying at the coverage rates and patterns recommended by the manufacturer. Ensure that sheet material has overlapped sealed joints and forms a complete waterproof cover over the entire concrete surface.

602.08 Backfilling. Backfill in accordance with Subsection 206A.10. Do not backfill concrete until it has completed the required curing period.

Measurement

602.09 Method. Use the method of measurement that is DESIGNATED IN THE SCHEDULE

Route Decommissioning 2016

Section 836-8 SPS

SPECIAL PROJECT SPECIFICATION

836-8 Route Decommissioning

836-8.01 Description This work consists of performing Route Decommissioning through the methods of Chunking and Ripping within the former unauthorized travelled way. This work also consists of Slashing whereby brush is spread over disturbed areas as described below. Work includes all labor and equipment and transportation necessary to perform the work in this specification.

836-8.02 Chunking (a.k.a pocking or gouging ) is a method used to intercept and trap sediment on a micro-scale. Chunking also collects moisture, which improves vegetation establishment and consequently prevents erosion. This method is highly recommended for moderate to steep slopes. But it is also useful for flat or gently sloping areas with erosive soils and arid climates. Chunking is most practical for use on small disturbed areas of fewer than fifty acres or for critical portions of large disturbances, such as highly erosive soils and areas adjacent to streams. When soils are shallow and bedrock is prominent, it may be necessary to add water bars and/or lead off ditches.

Basic Design and Construction

1. Use a small excavator or backhoe to create micro basins.

2. Dig a bucket load of soil to depth of 18-24 inches.

3. Drop bucket load 2-3 feet above the soil.

4. Repeat this process in a random and overlapping pattern throughout the site, making it impossible for water to flow down slope.

5. Finished roughened soil should be difficult to walk over.

6. Additional description may be found in Restoration of Forests, Grasslands, and Wetlands Damaged by Off-Highway Vehicles, available from the U.S. Government Printing Office.

836-8.03 Ripping is a method used to create intercepting ditches on a compacted surface along a contour line such that water will not readily travel along the ditch.

1. Shank Type Rippers

a. This work shall consist of ripping an existing roadbed with a shank type ripper.

b. The distance between the ripper shanks shall not exceed 36 inches. Rippers shall have a minimum of two shanks.

c. The minimum ripping depth shall be 20 inches. The Government may agree to a lesser depth when excessive rock is encountered.

d. Equipment shall not be operated on ripped areas.

2. Wing Rippers

a. This work shall consist of subsoiling an existing roadbed by ripping with a winged ripper.

b. The distance between ripper shanks shall not exceed 36 inches. Each shank shall be equipped with a shoe and wings which have a total width of at least 18 inches.

The design of the shank and wing will be such that the treated soils are slightly lifted and well fractured rather than plowed, mixed or displaced.

c. Ripping shall be accomplished to a minimum depth of 20 inches. The Government may agree to a lesser depth when excessive rock is encountered.
