D. Granular backfill material shall be crushed stone meeting IDOT Gradation Number 32. E. Trenches shall be backfilled in accordance with the following methods, in accordance with the

details on the Drawings: 1. METHOD 1 - This method applies to pipes under grassed yards and open spaces and

unimproved areas. In this method, the trench shall be backfilled with excavated


materials in a manner that will not dislodge or damage the pipe or cause bridging action in the trench. The material shall be deposited in uniform layers not exceeding 12-inches thick, loose measure. Each layer shall be compacted by ramming or tamping or, if directed by the IDNR Construction Inspector, inundated or deposited with water. Pipes in these areas will generally not require water jetting unless the IDNR Construction Inspector determines that early settlement is required. If jetting is used, it shall be considered incidental to piping installation and no additional compensation will be allowed. Top 4 inches shall be topsoil. Any rocks or clods greater than 2 inches in diameter shall be removed from the topsoil as it is spread. Top of the trench shall be left neatly rounded to allow for settlement.

2. METHOD 2 – This method applies to roadways or parking areas that do not have

permanent surfaces (gravel). In this case, the trench from top of granular bedding to 8 inches below ground surface shall be backfilled with excavated earthen materials in a manner that will not dislodge or damage pipe or cause bridging action in trench. The material shall be deposited in uniform layers not exceeding 12 inches in thickness, loose measure. Each layer shall be compacted by ramming or tamping. Eight (8) inches of aggregate shall be applied so that the finished surface of the aggregate is at the proposed surface elevation or matches the existing surface elevation.

3. METHOD 3 - This method applies to all pipes buried beneath existing utilities or

structures. In this case, the trench from the top of the granular pipe bedding to at least 6 inches above the existing utility or structure shall be backfilled with granular backfill. The granular material shall be deposited in uniform layers not exceeding 6 inches thick, loose measure, and each layer shall be compacted by ramming or tamping. Trench from 6 inches above the existing utility or structure to the surface shall then be backfilled in accordance with another applicable method; I, II, IV, V, VI, or VII.

4. METHOD 4 - This method applies to any area where the existing or new surface is

Portland cement concrete or bituminous concrete (asphalt). In this case, the trench from the top of the granular pipe bedding to the bottom of the existing or new surface shall be backfilled with granular backfill. Granular material shall be deposited in uniform layers not exceeding 6-inches thick, loose measure, and each layer shall be compacted by ramming or tamping.

5. METHOD 5 - This method applies to all pipes within earthen dikes. From the top of the

pipe bedding to 6 inches below the new finish grade, the trench shall be backfilled with earthen materials (similar to those used in the dike construction) in 8-inch layers. Fill top 6 inches of trench with topsoil or roadway aggregate, to match the existing dike surface.

F. Water Jetting Backfill:

1. Where water jetting is called for, all trench backfill shall be compacted by jetting and water soaking in the manner described below.

2. Trench compaction shall be started at the point of lowest elevation of the trench and work up along the trench.

3. Jetting and water soaking shall not begin until the trench has been backfilled to within 6 inches of the finished surface.

4. Holes through which water is injected into the backfill shall be centered over the trench


backfill and at longitudinal intervals of not more than 6 feet. 5. Additional holes shall be provided if deemed necessary by the IDNR Construction

Inspector to secure adequate settlement. 6. All holes shall be jetted and shall be carried to a point 1 foot above the top of the pipe. 7. Drilling the holes by means of augers or other mechanical means will not be permitted. 8. Care shall be taken in jetting so to prevent direct contact with, or other disturbances of

the pipe. 9. No more than 100 linear feet of completed sewer lines shall remain un-jetted at any one

time. 10. Water shall be injected at a pressure and rate just sufficient to sink the holes at a

moderate rate. 11. After a hole has been jetted to the required depth, the water shall continue to be injected

until it begins to overflow the surface. 12. CONTRACTOR shall, at his own expense, bore test holes at such locations as the IDNR

Construction Inspector may designate in order to determine the effectiveness of the water soaking.

13. Soil auger shall be used for boring test holes. 14. As soon as the jetting and water soaking has been completed, all holes shall be filled

with soil and compacted. 15. Surface depressions resulting from backfill subsidence caused by jetting and water

soaking shall be filled and re-compacted by tamping or rolling to the satisfaction of the IDNR Construction Inspector.

16. Water shall be furnished at the IDNR's expense. 17. CONTRACTOR shall use water only at those times designated by the IDNR. 18. CONTRACTOR shall conform to municipal ordinances, rules, or regulations concerning

its use. 19. Water jetting backfill shall be incidental to pipe line installations.

G. Where there is a deficiency of suitable backfill material due to a rejection of part or all of the

excavated material as unsatisfactory for backfill purposes, CONTRACTOR shall furnish satisfactory backfill material wasted from trench excavation in other locations or from other sources furnished by the CONTRACTOR. Backfill furnished and disposal of unsatisfactory material under these circumstances shall be incidental to piping installation.

H. Material for earthen backfill may be job-excavated material, free from debris, stones larger than 2

inches, organic matter, and frozen material.

I. Backfilling shall proceed so that not more than 100 feet intervals between the end of the backfilled section and the end of the laid pipe. No backfill material shall be placed until the IDNR Construction Inspector has examined the grade of the pipe.

J. Where the trenches have been sheeted or braced, care must be taken in removing the same to

keep the backfilling well above the lower ends of the sheeting or bracing so as to prevent caving of the sides of the trench down onto the pipe and displacing them or damaging structures along the sides of the trench.

K. Tamping shall be done with a hand held tamper or vibratory plate of 6 inches or less in width.

No other type of compaction equipment will be allowed. Care shall be used to place and tamp this backfill as not to disturb the joints, alignment, or grade of the pipe. Backfilling shall be carried on simultaneously on both sides of the pipe.


L. Where the trench excavation is within the public right-of-way, or within 5 feet of a roadway,

sidewalk, driveway, or wherever indicated on the Drawings, the trench backfill shall be tamped continuously to the surface with a mechanical tamper of a type approved by the IDNR Construction Inspector. All material shall be compacted to 95 percent of the Standard Proctor Density as determined by ASTM D1557. No layer of material being compacted shall exceed 1 foot in depth. IDNR Construction Inspector reserves the right to perform density tests after tamping is complete on any layer.

M. Where un-compacted backfill is indicated on the Drawings, the backfill material from top of the

granular backfill to the surface may be simply pushed into the trench and run over with the backfilling equipment.

2.05 SIDEWALK AND PAVEMENT MATERIALS

A. Concrete pavement, and all types of concrete base pavement, may be cut only where, in the manner and to the extent specified herein, or authorized by the IDNR Construction Inspector. Cuts shall be no larger than necessary to provide adequate working space for proper installation of pipe and pipeline appurtenances. Use concrete saw for the cutting of concrete pavements along each side of trenches and at structures. All cuts shall be a minimum of 2 inches deep or 1/4 the depth of the pavement, whichever is greater.

B. Concrete pavements over trenches excavated for pipelines shall be removed to a width not less

than 24 inches wider than the width of the trench at pavement subgrade. Trench width at pavement subgrade shall not exceed the minimum dimension that will allow good and safe construction except that no under cutting will be permitted. A shoulder not less than 12 inches in width, at any point, shall be left between the cut edge of the pavement and top edge of the trench. Pavement cuts shall be made to and between straight lines that, unless otherwise required, shall be parallel to the centerline of the trench.

C. Where the line of the trench parallels the length of concrete walks and the trench location is all or

partially under the walk, then the entire walk shall be removed and replaced. If necessary to remove concrete curbs, gutters, or walks, they shall be replaced to the existing joints.

D. Concrete streets and drives: Refer to Section 02520. Asphalt streets and drives: Refer to Section

02751.

C. Compact, level, and dampen base fill material under slabs on grade. Prior to placing

concrete, install polyethylene vapor barrier under interior slabs. Do not puncture or otherwise damage vapor barrier or membrane waterproofing.

D. Transport concrete to prevent separation of materials in accordance with ACI practices. Do

not add water to concrete during transporting. Handle from mixer to point of placement with carts, buggies, or conveyors. Do not dump concrete from mixer or from transporting equipment with a free fall of more than three feet. Deposit concrete as nearly to its final position as possible.

E. Clean transporting equipment at frequent intervals during placement. Do not use partially

hardened or contaminated concrete. 3.03 PLACEMENT OF CONCRETE

A. Place concrete in accordance with ACI 304 "Recommended practice for measuring, mixing, transporting and placing concrete" and as herein specified.

B. Deposit concrete continuously or in layers of such thickness that no concrete will be placed

on concrete which has hardened sufficiently to cause the formation of seams or planes of weakness. If a section cannot be placed continuously, provide construction joints as herein specified. Deposit concrete as nearly as practicable to its final location to avoid segregation.

C. Work concrete into corners and around reinforcement. Machine vibrate sufficiently to insure

thorough compaction and complete embedment of reinforcing. Stop placement at point of no shear, or where directed, and erect tight, plumb dams through forms.

D. Place concrete between construction joints in one continuous operation. Locate construction

joints in slabs under partitions. Brush on neat cement when pouring against hardened concrete.

E. Placing Concrete in Forms:

1. Deposit concrete in forms in horizontal layers not deeper than 24 inches and in a manner to avoid inclined construction joints.

2. Where placement consists of several layers, place each layer while preceding layer is still plastic to avoid cold joints.

3. Consolidate placed concrete by mechanical vibrating equipment supplemented by hand-spading, rodding or tamping. Use equipment and procedures for consolidation of concrete in accordance with ACI recommended practices.

4. Do not use vibrators to transport concrete inside forms. Insert and withdraw vibrators vertically at uniformly spaced locations not farther than visible effectiveness of machine.

5. Place vibrators to rapidly penetrate placed layer and at least 6-inches into preceding layer.


6. Do not insert vibrators into lower layers of concrete that have begun to set. 7. At each insertion, limit duration of vibration to time necessary to consolidate

concrete and complete embedment of reinforcement and other embedded items without causing segregation of mix.

E. Placing Concrete Slabs:

1. Deposit and consolidate concrete slabs in a continuous operation, within limits of construction joints, until the placing of a panel or section is completed.

2. Consolidate concrete during placing operations so that concrete is thoroughly worked around reinforcement and other embedded items and into corners.

3. Bring slab surfaces to correct level with straight edge and strike off. Use bull floats or darbies to smooth surface, free of humps or hollows. Do not disturb slab surfaces prior to beginning finishing operations.

4. Maintain reinforcing in proper position during concrete placement operations.

F. Cold Weather Placing:

1. Protect concrete work from physical damage or reduced strength which could be caused by frost, freezing actions, or low temperatures, in compliance with ACI 306, "Cold Weather Concreting," and as herein specified.

2. When air temperature has fallen to or is expected to fall below 40 degrees F, uniformly heat water and aggregates before mixing to obtain a concrete mixture temperature of not less than 40 degrees F and not more than 80 degrees F at point of placement, and maintain minimum temperature over the entire work for no less than 72 hours.

a. Do not use frozen materials or materials containing ice or snow. Do not place

concrete on frozen subgrade or on subgrade containing frozen materials. b. Do not use calcium chloride, salt and other materials containing antifreeze

agents or chemical accelerators unless otherwise accepted in mix designs. G. Hot Weather Placing:

1. When hot weather conditions exist that would seriously impair quality and strength of concrete, place concrete in compliance with ACI 305, "Hot Weather Concreting," and as herein specified.

2. Cool ingredients before mixing to maintain concrete temperature at time of placement below 90 degrees F. Mixing water may be chilled, or chopped ice may be used to control temperature provided water equivalent of ice is calculated in total amount of mixing water.

3. Cover reinforcing steel with water-soaked burlap if it becomes too hot, so that steel temperature will not exceed the ambient air temperature immediately before embedment in concrete.

4. Wet forms thoroughly before placing concrete. 5. Use water-reducing retarding admixture (Type A) when required by high

temperatures, low humidity, or other adverse placing conditions.

H. Construction Joints: CONTRACTOR to submit placement and type of construction joints to IDNR Construction Inspector for review prior to placement of any concrete on the project.


I. Expansion Joints:

1. Install expansion joint filler where interior slabs abut exterior walls, interior bearing walls and columns, at perimeter of concrete equipment pads, and other necessary locations as determined by the IDNR.

2. Omit expansion joint filler and install 15 pound felt, centered below doors, to break bond at exterior doors with concrete platforms, unless otherwise shown on the Drawings.

J. Control Joints:

1. Cut control joints in all exposed concrete slabs on grade, as directed by the Inspector. 2. Locate in a uniform pattern throughout parking areas. 3. Verify location and cut to depth of 1/6th of slab thickness with minimum of 3/4-inch

depth. 4. Cut with carborundum saw, approximately 6 to 24 hours after placing concrete and

when a minimum amount of raveling occurs in concrete. 5. On exterior walks, score with 1/4-inch by 1-inch deep control joints. Use straight

edge guide when scoring joints. Where required depth of control joint cannot be made by scoring, cut joints with carborundum saw.
