Unless otherwise permitted in writing by the Engineer because of conditions encountered in construction, all pipe culverts, except entrance culverts, shall be constructed according to the following.
a.Removal and Replacement of Unstable or Unsuitable Material or Rock. Where unstable material such as soft or spongy soil, unsuitable material, or rock in either ledge or boulder formation is encountered at locations along the line of the pipe culvert and at the grade established for the culvert, the material or rock shall be removed and replaced before proceeding with the construction. The unstable and unsuitable material shall be removed to a depth determined by the Engineer and for a width of one diameter (or equivalent diameter) of the pipe on each side of the pipe culvert, and replaced with aggregate. Rock shall be removed to an elevation 1 ft (300 mm) lower than the bottom of the pipe or to a depth equal to 1/2 in./ft (40 mm/m) of ultimate fill height over the top of the pipe culvert, whichever is the greater depth, and for a width as specified in (b) below, and replaced with aggregate. Replacement material shall be placed in 8 in. (200 mm) lifts, loose measurement, and compacted by mechanical means to the satisfaction of the Engineer.
b.Trenching. Pipe culverts shall be constructed in trenches free of water, excavated either in embankments or natural ground. Water shall be removed by use of a diversion channel or by other methods approved by the Engineer. When all or a portion of a pipe will be in fill, the embankment, or a portion thereof, shall be constructed prior to excavating the trench. The embankment shall be constructed to a height which will provide approximately 1 ft (300 mm) of cover over the pipe, except that in no case shall the height of the embankment constructed result in a finished trench depth exceeding 5 ft (1.5 m). The width of the top of the embankment shall be a minimum of 13 ft (4 m) on each side of the pipe culvert, measured at right angles to its centerline, and the longitudinal slopes shall be 1:6 (V:H) or flatter. The embankment shall be constructed according to the requirements of Section 205, except the material shall be select material from excavation or borrow, meeting the approval of the Engineer. Trenches shall be excavated to an elevation 4 in. (100 mm) below the bottom of the pipe and to the following widths. Inside Diameter or Equivalent Diameter of Pipe Required Trench Width On Each Side of the Pipe 24 in. (600 mm) and less 9 in. (225 mm) Greater than 24 in. (600 mm) up to 48 in. (1.2 m) 12 in. (300 mm) Greater than 48 in. (1.2 m) 18 in. (450 mm) Pipe Culverts Art. 542.04 The faces of the excavated trench shall be vertical. If the width of the trench at the top exceeds the maximum horizontal dimension of the pipe by more than the above specified widths as a result of careless or faulty construction methods, that portion of the trench shall be corrected by backfilling in 8 in. (200 mm) lifts and again excavating the trench to the required width.
c.Preparation of Foundation. Compacted aggregate, at least 4 in. (100 mm) in depth below the pipe culvert, shall be placed the entire width of the trench and for the length of the pipe culvert, except compacted impervious material shall be used for the outer 3 ft (1 m) at each end of the pipe culvert. When the trench has been widened by the removal and replacement of unstable or unsuitable material, the foundation material shall be placed for a width not less than the above specified widths on each side of the pipe culvert. The aggregate and impervious material shall be compacted by mechanical means to the satisfaction of the Engineer. When pipe having bells or hubs is used, cross trenches not more than 2 in. (50 mm) wider than the bell or hub shall be excavated to provide uniform bearing along the length of the pipe.
d.Laying Pipe. No pipe culvert shall be placed until the trench and the prepared foundation have been approved by the Engineer. The pipe shall be laid so that the flow line of the finished culvert will be at the grade shown on the plans or established by the Engineer. Laying of pipes shall commence at the outlet end, with the spigot ends of the pipe pointing in the direction of the flow, and proceed toward the inlet end with pipes abutting. The ends of the pipe shall be carefully cleaned before the pipes are placed and the pipes shall be placed to avoid unnecessary handling on the foundation. As each length of the pipe is laid, the ends of the pipe shall be protected to prevent the entrance of any material. The pipes shall be fitted and matched so that when laid in the work, they will form a culvert with a smooth, uniform invert. All joints in concrete culverts shall be sealed with rubber gaskets, preformed flexible joint sealants, mastic joint sealer, or external sealing bands. When mastic joint sealer is used, the material shall completely fill the joint after the pipes have been brought together. After each joint is sealed, it shall be wiped clean on the inside. Each section of pipe shall be pushed or pulled to the section in place to ensure tight joints. Pipe having a diameter or equivalent diameter greater than 42 in. (1 m) shall be set or "brought home" with a winch, come-a-long, or other positive means. Handling holes in concrete pipe shall be filled with a precast concrete plug and sealed with mastic or mortar; or filled with a polyethylene plug. The plug shall not project beyond the inside surface after installation. When corrugated steel or aluminum alloy culvert pipe (including bituminous coated steel or aluminum and precoated steel) is used, the pipe shall be placed such that the longitudinal lap is placed at the sides and separate A rt. 542.04 Pipe Culverts sections of pipe shall be joined with a hugger-type band. When the pipes are fabricated with a smooth sleeve-type coupler, the gasket material shall be according to Article 1006.01. PVC, PE, and CPP pipes shall be joined according to the manufacturer’s specifications.
e.Elongation. Circular corrugated steel or aluminum alloy culvert pipe (including bituminous coated steel or aluminum and precoated steel) that are specified as elongated in Table IB or IC shall be elongated vertically 5 percent ± 0.75 percent out of a round before any fill is placed. The pipe, except for bituminous coated corrugated steel or aluminum culvert pipe, shall be elongated by one of the following methods.
1.Deformation during fabrication.
2.Elongation by the use of wires, rods, or straps during fabrication.
3.Elongation at the time of installation by the use of vertical struts, wedged or jacked inside the pipe in a manner approved by the Engineer. Bituminous coated corrugated steel or aluminum culvert pipe shall be elongated by either method (1) or (2) prior to coating. Pipe elongated by the manufacturer shall be marked to show the top. The pipe shall be stored, transported, and handled in such a manner so that at the time of installation the pipe shall have retained its elongation. When the pipe is elongated by method (2) or (3), it shall be installed in a manner that will permit the gradual reduction of elongation as the fill over the pipe is placed. This reduction in elongation shall be as directed by the Engineer and may be accomplished by the use of softwood compression caps when struts or jacks are used, or by the use of turnbuckles or other devices when wires, rods, or straps are used. After the fill has been placed and compacted, all struts, wires, rods, or straps shall be removed and any holes in the pipe resulting from their use shall be plugged in a manner satisfactory to the Engineer. Heavy asphaltic or tar material, or other material, or a device meeting the approval of the Engineer may be used to plug the holes. No strutting or elongation will be permitted on corrugated steel or aluminum (including bituminous coated steel or aluminum and precoated steel) pipe arches.
f.Backfilling. As soon as the condition of the pipe culvert will permit, the entire width of the trench shall be backfilled with aggregate to a height of at least the center of the pipe. The aggregate shall be placed longitudinally along the pipe culvert, except at the outer 3 ft (1 m) at each end of the culvert which shall be backfilled with impervious material. The elevation of the backfill material on each side of the pipe shall be the same. The space Pipe Culverts Art. 542.04 under the pipe shall be completely filled. The aggregate and impervious material shall be placed in lifts not exceeding 8 in. (200 mm) in depth, loose measurement, and compacted by mechanical means to the satisfaction of the Engineer. When using flexible pipe, as listed in the first table of Article 542.03, the aggregate shall be continued to a height of at least 1 ft (300 mm) above the top of the pipe and compacted to a minimum of 95 percent of standard lab density by mechanical means. The installed pipe and its embedment shall not be disturbed when using movable trench boxes and shields, sheet pile, or other trench protection. The remainder of the trench shall be backfilled as follows.
1.Trench Backfill. For trenches made in the subgrade of the proposed improvement, and trenches where the inner edge of the trench is within 2 ft (600 mm) of the proposed edge of pavement, curb, gutter, curb and gutter, stabilized shoulder, or sidewalk, the remainder of the trench shall be backfilled with trench backfill material meeting the requirements of Section 208. The material shall be placed in lifts not exceeding 8 in. (200 mm) in depth, loose measurement, and compacted to a minimum of 85 percent of standard lab density by mechanical means.
2.Select Material. For all other trenches, the remainder of the trench shall be backfilled with select material. The select material shall be from excavation or borrow, free from large or frozen lumps, clods, or rock, meeting the approval of the Engineer. The material shall be placed in lifts not exceeding 8 in. (200 mm) in depth, loose measurement, and compacted to 95 percent of standard lab density by mechanical means. Before compaction, each lift shall be wetted or dried to bring the moisture content within 80 to 110 percent of optimum as determined according to Illinois Modified AASHTO T 99 (Method C). The Contractor may, at no additional cost to the Department, backfill the remainder of the trench with aggregate in lieu of select material. The aggregate shall be placed in lifts not exceeding 8 in. (200 mm) in depth, loose measurement and compacted by mechanical means to the satisfaction of the Engineer. The outer 3 ft (1 m) at each end of all trenches shall be backfilled with impervious material. The material shall be placed in lifts not exceeding 8 in. (200 mm) in depth, loose measurement and compacted to 95 percent of standard lab density by mechanical means. In lieu of trench backfill or select material, the Contractor may, at no additional cost to the Department, backfill the entire trench, excepting the outer 3 ft (1 m), with controlled low-strength material according to Section 593. Art. 542.04 Pipe Culverts All backfill material shall be placed in such a manner as not to damage the culvert. The filling of the trench shall be carried on simultaneously on both sides of the pipe. When the trench has been widened for the removal and replacement of unstable or unsuitable material, the backfilling with aggregate and impervious material, will be required for a width of at least the specified widths on each side of the pipe. The remaining width of each lift may be backfilled with select material. Each 8 in. (200 mm) lift for the entire trench width shall be completed before beginning the placement of the next lift.
g.Embankment. When the top of the completed backfill is less than 1 ft (300 mm) above the top of the pipe, embankment shall be constructed to an elevation of 1 ft (300 mm) over the top of the pipe. The width and longitudinal slopes of the embankment shall be as specified in
Article 542 — 04(b).
The embankment shall be constructed according to Section 205, except the material shall be select material, from excavation or borrow, meeting the approval of the Engineer. While constructing the embankment, no loads, other than the equipment permitted by the Engineer for the construction of the embankment, shall be introduced upon the pipe culvert and no heavy earth-moving equipment will be permitted within 4 ft (1.2 m) of either side of the pipe culvert.
h.Additional Embankment. After the trench has been backfilled and embankment constructed to an elevation of 1 ft (300 mm) over the top of the pipe culvert, additional embankment shall be constructed before the Contractor will be permitted to introduce any loads upon the pipe culvert. The required cover, including any embankment cover over the pipe and additional embankment, shall be sufficient for the maximum load, including the weight of equipment, which the Contractor proposes to operate or move across the pipe culvert. The total cover required for various construction loadings shall be the responsibility of the Contractor. Additional embankment shall be constructed according to Section 205. Its width on each side of the pipe culvert shall be 13 ft (4 m) and the longitudinal slopes shall not be steeper than 1:6 (V:H). The width of the additional embankment, measured along the pipe culvert, shall be the actual fill width indicated on the cross sections at the elevation required per the Contractor’s design or sufficient to accommodate two-way traffic of the Contractor’s grading operations and so no equipment is operated within 10 ft (3 m) of either shoulder line, whichever is the least.

Pipe Culverts Art. 542.05
i.Deflection Testing for Pipe Culverts. All PE, PVC, and CPP pipe culverts shall be tested for deflection not less than 30 days after the pipe is installed and the backfill compacted. The testing shall be performed in the presence of the Engineer. For PVC, PE, and CPP pipe culverts with diameters 24 in. (600 mm) or smaller, a mandrel drag shall be used for deflection testing. For PVC, PE, and CPP pipe culverts with diameters over 24 in. (600 mm), deflection measurements other than by a mandrel shall be used. Where the mandrel is used, the mandrel shall be furnished by the Contractor and pulled by hand though the pipeline with a suitable rope or cable connected to each end. Winching or other means of forcing the deflection gauge through the pipeline will not be allowed. The mandrel shall be of a shape similar to that of a true circle enabling the gauge to pass through a satisfactory pipeline with little or no resistance. The mandrel shall be of a design to prevent it from tipping from side to side and to prevent debris build-up from occurring between the channels of the adjacent fins or legs during operation. Each end of the core of the mandrel shall have fasteners to which the pulling cables can be attached. The mandrel shall have nine various sized fins or legs of appropriate dimension for various diameter of pipes. Each fin or leg shall have a permanent marking that states its designated pipe size and percent of deflection allowable. The outside diameter of the mandrel shall be 95 percent of the base inside diameter, where the base inside diameter is:
1.For all PVC pipe: as defined using ASTM D 3034 methodology.
2.For all PE and CPP pipe: the average inside diameter based on the minimum and maximum tolerances specified in the corresponding ASTM or AASHTO material specifications. If the pipe is found to have a deflection greater than that specified, that pipe section shall be removed, replaced, and retested.
542.05 Method II Construction. Method II Construction may be used to
construct pipe culverts, except entrance culverts, only when specified or when physical conditions are encountered in construction which make the use of Method I Construction impractical and written permission is obtained from the Engineer.

Additional trenching may be necessary in some cases due to the location of a pipe culvert. The trenching shall be performed as specified for Method II, except as follows. The trench shall be excavated only to the bottom of the pipe culvert and for a width sufficient to place the pipe. The bottom of the trench shall be shaped to approximately the size and shape of the pipe culvert.
b.Preparation of Foundation. After the trench has been excavated for the entire length of the pipe culvert and any necessary removal and replacement of unstable or unsuitable material or rock has been completed, the bottom of the trench shall be shaped to substantially fit the exterior of the pipe. If necessary, material meeting the approval of the Engineer shall be used to fill depressions. The material comprising the foundation shall then be compacted to the satisfaction of the Engineer.
c.Laying Pipe. The pipe shall be laid as specified in Article 542.04(d).
d.Backfill and/or Embankment. As soon as the condition of the pipe culvert will permit, the trench shall be backfilled and/or embankment constructed. The material used shall be select material, meeting the approval of the Engineer, from excavation or borrow. The material shall be placed in lifts not exceeding 8 in. (200 mm), loose measurement, and compacted by mechanical means to the satisfaction of the Engineer. Special care shall be taken to completely fill the space under the pipe. The material shall be placed to an elevation 1 ft (300 mm) above the top of the pipe culvert or to the finished grade, whichever is the lesser height. When embankment is being constructed, the material used for its construction shall be placed to a width, on each side of the pipe culvert, not less than one diameter of the pipe.
