New Installation Guidelines

Current breakaway requirements can be met on new installations by using the new transformer base and pole designed for that base, both approved by the FHWA to meet ’85 AASHTO standards.
TxDOT typically uses breakaway poles wherever possible, even when not required. For these types of new installations, where breakaway poles are used but not required (outside the clear zone or behind barriers), transformer base poles meeting the ’75 AASHTO guidelines may be used when currently in stock but should not be considered breakaway.
Do not use shims or washers to level breakaway base, because this may change the breakaway characteristics of the base. Ensure that the top of the concrete foundation is level.
