FHWA Accepted Breakaway
HAPCO Leads the Industry in Federal Highway Administration (FHWA) Accepted Breakaway Options.
The Federal Highway Administration (FHWA) definition of “Breakaway” refers to crash-tested devices that break or yield upon impact. FHWA guidelines require the specification of Breakaway poles and bases meeting rigorous impact testing to mitigate the potential severity of crashes, providing a safer outcome in the event of a collision.
The FHWA accepts certain poles and bases for use on breakaway applications under provisions adopted from the American Association of State and Highway Transportation Officials’ (AASHTO) Standard Specifications for Structural Supports for Highway Signs, Luminaires and Traffic Signals. Testing parameters used in determining acceptable breakaway performance are found in the National Cooperative Highway Research Program (NCHRP) Report 350, Recommended Procedures for the Safety Performance Evaluation of Highway Features.
4-Bolt Breakaway Anchor Base
Hapco’s Anchor Base was the first pole anchoring shoe base allowing standard installation techniques to meet FHWA Breakaway provisions. Its simplicity of design eases the installation process, combining the most cost efficient Breakaway device in the industry with the aesthetic appeal of a standard shoe base.
Hapco offers Transformer Base (T-Base) designs to accommodate a wide range of pole sizes and bolt circle requirements. The historic appearance of the T-Base design offers a higher probability of re-use of the pole in the event of a knockdown.
The X-Base, a Hapco exclusive, is welded to the bottom of the base as part of the pole assembly. It is supplied assembled and serves as the base flange, bolting directly to the anchor bolts. The X-Base extends the range of sizes for FHWA accepted Breakaway poles to a 10” Butt Diameter and 55’ Mounting Heights.
Breakaway couplings are available for use in a wide range of pole sizes. Lifetime Warranty
Aluminum pole assemblies incorporating FHWA Accepted Breakaway Devices are covered under Hapco’s exclusive Lifetime Warranty.
Aluminum poles used in direct buried applications throughout the country have a 60 year record of successful installations and can provide significant overall job savings.
Through an extensive process of expert design, modeling, and testing, Hapco engineers have created a breakaway design that brings the cost efficient properties of direct buried poles to our FHWA accepted Breakaway product line.
The butt end of Hapco Direct Buried Breakaway poles are partially flattened into an anti-rotational, oval cross section.
