832.06 Drainage Trough Material for Open Type Expansion Dam Units.
Drainage trough material furnished for use shall be a high grade neoprene reinforced with at least two layers of flexible polyester or nylon cord fabric acceptable to the Engineer meeting the following requirements.
1.Fabric reinforcement shall be a close woven material providing equal strength in both warp and fill directions.
2.The finished product shall be of the shape, size, and thickness shown by the plan details meeting the following test: Oil Deterioration - Maximum weight {mass} change of 55% after immersion in IRM Oil 903 for 70 hours at 212 °F {100 °C} - ASTM D 471.
3.Only minimum splicing across the width of the required material will be allowed. Any splice allowed must be performed using materials and in a manner recommended by the producer of the material so as to provide a waterproof, full strength (same as original material) joint through the splice. Samples (12 inch x 12 inch {300 mm x 300 mm} minimum) of the material along with the material data sheet of the producer of the material shall be submitted to the Central Laboratory for approval.

833.03 Lagging Timber.
Lagging timber shall be fresh, rough-cut hardwood. Lagging timber design and selection to be the responsibility of the contractor. SECTION 834 PILING MATERIALS
834.01 Concrete Piles.
Precast prestressed concrete piles shall be manufactured in accordance with the requirements given in Section 513.
834.02 Steel Pile Point Protectors.
The pile points shall be fabricated from cast steel meeting or exceeding the requirements of AASHTO M 103M. The pile points shall be properly identified as to the heat from which they were fabricated, either by this number being cast into the point or by being legibly stenciled on each point. Certified mill test reports shall be submitted for the pile points in accordance with the requirements given for the submittal of certified mill test reports for Structural Steel.
834.03 Steel Bearing Piles.
The material in rolled steel piles and splices shall conform to the requirements of AASHTO M 270 {AASHTO M 270M}, unless otherwise specified by plan details. All piles shall be rolled steel sections of the section number, size, and weight per foot {mass per meter} indicated on the plans and shall be fabricated in conformity with the requirements of ASTM A 6 {ASTM A 6M}. The heat number and section size shall be legibly marked on each piece by stamp, paint, tag, sticker or other industry accepted method. Any piece that cannot be properly identified at time of use will be rejected.
834.04 Steel Sheet Piles.
Permanent steel sheet piling shall be of the type called for on the plans and shall conform to the requirements of AASHTO M 202 {AASHTO M 202M} and its supplementary requirement, S1. Temporary steel sheet piling shall conform to the requirements of AASHTO M 202 {AASHTO M 202M} and its supplementary requirement, S1 and may be either new piling or used piling, acceptable to the Engineer for the intended function. The temporary steel sheet piling shall be interlocking type piles having a 3/8 inch {9.4 mm} minimum web thickness.
834.05 Storing and Handling Steel Piles.
When placed in the leads, the pile shall conform to camber and sweep permitted by allowable mill tolerance. The method of storing and handling shall be such as to avoid undue bending stresses or other injury. Piles bent, cracked, or otherwise injured will be rejected. SECTION 835 STEEL REINFORCEMENT
835.01 General.
All reinforcing steel shall be Grade 60 {Grade 420} steel, unless otherwise stipulated in these Specifications or specifically designated by plan details. All steel reinforcement bars (smooth and deformed) must come from an ALDOT approved steel mill. Approved steel mills are listed in the Department’s Materials, Sources and Devices with Special Acceptance Requirements Manual, List I-12, Deformed and Plain Steel Bar Producing Mills. All reinforcing bars over 1/4 of an inch {6 mm} in diameter shall have deformations as prescribed in AASHTO M 31.
835.02 Reinforcing Bars.
Steel reinforcement bars 1/4 of an inch {6 mm} or less in diameter shall meet the requirements of AASHTO M 32. Steel reinforcement bars over 1/4 of an inch {6 mm} in diameter shall meet the requirements of AASHTO M 31.
