430-6.5 Use of Tunnel Liner: When the railroad company requires that a tunnel liner be
used for placing the pipe in lieu of the jacking method, the Department will pay for the tunnel liner material separately in cases where the Contract Documents do not require the use of a tunnel liner. For these cases the Department will reimburse the Contractor for the actual cost of the liner, deliver ed at the site. The Department will base such cost on a liner having the minimum gage acceptable to the railroad.
430-7 Specific Requirements for Concrete Pipe.
430-7.1 Sealing Joints : Seal the pipe joints with round rubber or profile gaskets meeting
the requirements of Section 449. Ensure that the gasket and the surface of the pipe joint, including the gasket recess, are clean and free from grit, dirt , and other foreign matter, at the time the joints are made. In order to facilitate closure of the joint, application of a vegetable soap lubricant immediately before closing of the joint will be permitted. Prelubricated gaskets may be FY 2023-24 Return to Table of Contents used in lieu of a vegetable soap lubricant when the lubricating material is certified to be inert with respect to the rubber m aterial.
430-7.2 Laying Requirements for Concrete Pipe with Rubber Gasket Joints: Do not
allow the gap between sections of pipe to exceed 5/8 inch for pipe diameters of 12 inches through 18 inches, 7/8 inch for pipe diameters of 24 through 66 inches, and 1 inch for pipe diameters 72 inches and larger. Where minor imperfections in the manufacture of the pipe create an apparent gap in excess of the tabulated gap, the Engineer will accept the joint provided that the imperfection does not exceed 1/3 the circum ference of the pipe, and the rubber gasket is 1/4 inch or more past the pipe joint entrance taper. Where concrete pipes are outside of these tolerances, replace them at no expense to the Department. Do not apply mortar, joint compound, or other filler to t he gap which would restrict the flexibility of the joint.
430-7.3 Field Joints for Elliptical Concrete Pipe: Use either a preformed plastic gasket
material or an approved rubber gasket to make a field joint.
430-7.3 1 Plastic Gasket: Meet the following requirements when field joints are

details to the Engineer regarding configuration of the joint and the amount of gasket material required to affect a satisfactory seal. Do not brush or wipe joint surfaces which are to be in contact with the gasket material with a cement slurry. Fill minor voids with cement slurry.
430-7.3 1.4 Primer: Apply a primer of the type recommended by the
manufacturer of the gasket material to all joint surfaces which are to be in contact with the gasket material, prior to application of the gasket material. Thoroughly clean and dry the surface to be primed.
430-7.3 1.5 Application of Gasket: Apply gasket material to form a
continuous gasket around the entire circumference of the leading edge of the tongue and the groove joint, in accordance with the detail shown on Standard Plans, Index 430-001. Do not remove the paper wrapper on the exterior surface of the gasket material until immediately prior to joining of sections. Apply plastic gasket mater ial only to surfaces which are dry. When the atmospheric temperature is below 60ºF, either store plastic joint seal gaskets in an area above 70ºF, or artificially warm the gaskets to 70ºF in a manner satisfactory to the Engineer.
430-7.3 1.6 Installatio n of Pipe: Remove and reposition or replace any
displaced or contaminated gasket as directed by the Engineer. Install the pipe in a dry trench. Carefully shape the bottom of the trench to minimize the need for realignment of sections of pipe after they are placed in the trench. Hold to a minimum any realignment of a joint after the gaskets come into contact. Prior to joining the pipes, fill the entire joint with gasket material and ensure that when the pipes are joined there is evidence of squeeze -out of gasket material for the entire internal and external circumference of the joint. Trim excess material on the interior of the pipe to provide a smooth interior surface. If a joint is defective, remove the leading section of pipe and reseal the joint.

430-8.1 Field Joints :
430-8.1 1 General: Make a field joint with locking bands, as specified in
Article 9 — of AASHTO M36 and AASHTO M196M for aluminum pipe. For aluminum pipe,
fabricate bands from the same alloy as the culvert sheeting. When existing pipe to be extended is helically fabricated, make a field joint between the existing pipe and the new pipe using one of the following methods:
1.Cut the new pipe to remove one of the re -rolled annular end sections required in Sections 943 or 945, or fabricate the pipe so that the re -rolled annular section is fabricated only on one end. Use either a spiral (helical) band with a gasket or a flat band with gaskets as required by 430 -8.1.2 (2) to join the pipe sections.
2.The Contract or may construct a concrete jacket as shown on Standard Plans, Index 430-001.
430-8.1 2 Side Drain, Storm and Cross Drain, and Gutter Drains: Where
corrugated metal pipe is used as side drain, storm and cross drain, or gutter drain, use a rubber or neoprene gasket of a design shown to provide a joint as specified in 430 -4. Use a gasket of one of the following dimensions:
1.For annular j oints with 1/2 inch depth corrugation: either a single gasket a minimum of 7 inches by 3/8 inch or two gaskets a minimum of 3 -1/2 inches by 3/8 inch; and for annular joints with 1 inch depth corrugations: either a single gasket a minimum of 7 inches by 7/8 inch or two gaskets a minimum of 3 -1/2 inches by 7/8 inch.

When two gaskets are used, seal the overlapping area on the coupling band between the gaskets consistent FY 2023-24 Return to Table of Contents with the joint performance spec ified. The Contractor may tuck a strip of preformed gasket material over the bottom lip of the band for this purpose. Use coupling bands that provide a minimum circumferential overlap of 3 inches. As the end connections on the coupling band are tightened, ensure that there is no local bending of the band or the connection. Use precurved coupling bands on pipe diameters of 24 inches or less. Use flat gaskets mee ting the requirements of ASTM D1056, designation 2C2 or 2B3. In placing flat gaskets on pipe pr ior to placing the coupling band, do not stretch the gasket more than 15% of its original circumference. Use circular gaskets mee ting the requirements of ASTM C361. Do not stretch the circular gasket more than 20% of its original circumference in placing t he gasket on pipe. Use preformed plastic gasket material meeting the composition requirements of 942 -2.2. Apply an approved vegetable soap lubricant, as specified for concrete pipe in 430-7.1.1.
430-8.1 3 Alternate Joint: In lieu of the above -specified combination of locking

1.Use the metal bands as spe cified in Article 9 of AASHTO M36M that are at least 10 -1/2 inches wide and consist of a flat central section with a corrugated section near each end, designed to match the annular corrugation in the pipe with which they are to be used. Connect the bands in a manner approved by the Engineer, with a suitable fas tening device such as the use of two galvanized 1/2 inch diameter bolts through a galvanized bar and galvanized strap, suitably welded to the band. Use a strap that is the same gage as the band. Where helically corrugated pipe is to be jointed by this a lternate combination, ensure that at least the last two corrugations of each pipe section are annular, and designed such that the band will engage each pipe end with the next -to-outside annular corrugation.
2.For these bands, use a rubber gasket with a circular cross -section of the “O-ring” type conforming to ASTM C361. Use gaskets having the following cross -sectional diameter for the given size of pipe: Table 430-2 Non-SI Units Pipe Size Gasket Diameter 12 inches through 36 inches (with 1/2 inch depth corrugations) 13/16 inch 42 inches through 96 inches (with 1/2 inch depth corrugations) 7/8 inch 36 inches through 120 inches (with 1 inch depth corrugations) 1-3/8 inches Use preformed gasket material to seal the overlapping area on the coupling band between gaskets.
3.Use channel band couplers in helical pipe with ends which have been reformed and flanged specifically to receive these bands. Use channel band couplers that are of a two piece design, are fabricated from galvanized steel stock conforming to AASHTO M36, have 2 inch by 2 inch by 3/16 inch angles fastened to the band ends to allow for proper tightening, and meet the following: FY 2023-24 Return to Table of Contents Table 430-3 Non SI Units Band Thickness Pipe Wall T hickness 0.079 inch 0.109 inch or lighter 0.109 inch 0.138 inch or heavier 3/4 inch wide 0.109 inch or lighter 1 inch wide 0.138 inch or heavier Furnish two 1/2 inch diameter connection bolts with ea ch band, that conform to ASTM A307, Grade A and are electroplated in accordance with ASTM B633. Use a gasket with the joint that is a hydrocarbon blend of butyl rubber meeting the chemical composition and physical properties of 942 -2.2. Use a 3/8 by 3/4 inch gasket for pipe fabricated fro m 0.109 inch or lighter material and a 3/8 by 1 inch gasket for pipe fabricated from 0.138 inch and heavier material. The Contractor may use a flange band coupler without the gasket for all applications other than side drain, storm and cross drain, and gutter drain. Do not use the flange band coupler to join dissimilar types of pipe. The Contractor may join reformed flanged helical pipe to existing annular or reformed pipe having annular ends. On non -gasketed installations, use either an annular ba nd or an alternate joint described in 430 -8.1.3. On gasketed installations, use an annular band, minimum of five corrugations in width, in conjunction with two O -ring gaskets as specified in
430-8.1 3. Use mastic material to seal the area of band overlap.
The minimum joint performance standards specified in 430 -4.1 apply.
