891.05Prestressed Concrete Poles

Concrete, reinforcing steel and prestressing steel for prestressed concrete poles shall meet the requirements given in Section 513. The concrete shall have a minimum 28-day compressive strength of 5000 psi {35 MPa} or as shown on the plans. The prestressed concrete pole manufacturing plant shall follow the applicable requirements in ALDOT–367, Section 2, except that plant certification by the Precast/Prestressed Concrete Institute Plant Certification Program will not be required. Within 30 days after the award of the contract, the Contractor shall notify the Materials and Tests Engineer in writing of the name and address of the fabricator of the poles. Fabrication will not be allowed to begin until two weeks after the Materials and Tests Engineer has all of the approved details and submittals that are required for a representative of the Department to adequately inspect the fabrication of the poles. The Contractor shall arrange for a representative of the Department to conduct an inspection of the plant facilities and review the plant’s Quality Control/Quality Assurance manual during this two-week time period.

891.06Breakaway Supports

A Federal Highway Administration approved breakaway support shall be installed on each luminaire assembly when indicated on the plans. The pole shall meet the 1985 AASHTO breakaway requirements and FHWA certification of testing must be submitted. The Contractor shall assure the compatibility of the pole base, breakaway support and foundation. Transformer bases shall be used only as a replacement of a like item on an existing installation unless specifically shown otherwise on the plans.

891.07Mast Arms

Mast arms shall be fabricated from steel tubes (except for aluminum poles, which shall have aluminum mast arms) to the lengths specified on the plans and approved shop drawings. Mast arm shafts shall be of one continuous piece without intermediate splices or couplings, provided with rain-tight connections to the shaft of the pole and designed to rotate three hundred and sixty degrees in the horizontal plane. A two piece section, slip joint shaft mast arm will be permitted when plans or proposal require mast arms longer than the manufacturer's length capability. All hardware, except split pole clamps, shall be stainless steel or anodized aluminum. The end of the arm shall be furnished with the type of fitting required by the plans. All connecting joints for attachments for mast arms, shaft extensions and luminaire arms shall be of the design indicated by plan details or approved by the Engineer and shall develop full strength of the joint.

891.08Anchor Bolt Assemblies

Anchor bolt assemblies (anchor bolts, nuts, and washers) shall be in accordance with AASHTO M 314, Grade 36 or Grade 55, except maximum tensile strength on all grades is waived, and capable of transferring the load safely from the structure base plate to the foundation. The exposed end of the anchor bolts shall be threaded (rolled or cut type) and provided with appropriate nuts, including lock nuts and flat washers. The anchor bolts, nuts, and washers shall be hot-dipped galvanized in accordance with AASHTO M 232, however, galvanization of the bolt below 6 inches {152 mm} from the top of the embedment line will not be required. The nuts shall be lubricated with a lubricant containing a visible dye so that a visual check can be made for proper lubrication prior to installation. Special care shall be taken when storing galvanized bolts with a water-soluble lubricant. Anchor bolts for overhead roadway sign structures and high mast lighting assembly poles only, shall meet the requirements provided in AASHTO T 244 for Charpy V-Notch testing. Notch toughness tests on specimens shall be performed in accordance with Test Frequency P (Piece Testing) of AASHTO T 243 with a minimum average value of 15 ft-lb. at 40 F {20 J at 4.4 C} and the notch shall be oriented perpendicular to the longitudinal axes of the anchor bolt. In order to meet the Charpy V-Notch impact requirements, the steel may require heat treatment. The Charpy V-Notch testing equipment shall be calibrated once each year using a National Institute of Standards and Technology check sample. Certification of the annual calibration shall be available to the Department when requested.

891.09Pedestals

If specified by the plans, pedestals shall be furnished for steel and aluminum poles according to the overall length (including cap and base) shown on the plans. Pedestal shafts shall be a one-piece, STRUCTURAL MATERIALS FOR TRAFFIC CONTROL DEVICES AND HIGHWAY LIGHTING 813

continuous taper or parallel wall, circular shaft. Steel shafts shall be of not less than 1/8 inch {3 mm} wall thickness and of a size at the top designed to fit a standard 4 inch {102 mm} slip-fitter attachment. Steel shafts shall have a polished or galvanized finish, which shall be protected during storage and shipment by a suitable protective covering. The covering shall remain on the shaft until installation begins. A one-piece base shall be provided which, when attached to the shaft, will develop the full strength of the shaft to resist bending action. The base shall be provided with four slotted holes for attachment to the base of the foundation. The anchor bolts shall be recessed and ornamental covers provided. A handhole with cover, approximately 4 inches by 6 inches {102 mm by 153 mm} in dimension, shall be provided in the base of the pedestal shaft. A cap for any exposed open end of a pedestal shaft shall be provided. The cap shall be of cast aluminum and of the nipple or tenon mounting type.
