SPECIFICATION - ALUMINUM STRUCTURAL PLATE

Scope: This specification covers the manufacture and installation of the aluminum structural plate structure detailed in the plans.

Material: The aluminum structural plate structure shall consist of plates and appurtenant items as shown on the plans and shall conform to the requirements of AASHTO M 219 and ASTM B 746.

The corrugated plate (and ribs if required) shall be curved and bolt hole punched at the plant. Plate thickness and rib spacings shall be as indicated on the plans. All manufacturing processes including corrugating, punching, curving and galvanizing shall be performed within the United States using raw materials made in the

United States.

Bolts and nuts shall conform to the requirements of ASTM

A307 or ASTM A449.

Assembly: The structure shall be assembled in accordance with the shop drawings provided by the manufacturer and per the manufacturer’s recommendations. Bolts shall be tightened using an applied torque of between 100 and 150 ft.-lbs.

Installation: The structure shall be installed in accordance with the plans and specifications, the manufacturer’s recommendations, and the AASHTO Standard Specifications for Highway Bridges, Section 26 (Division II).

Backfill: The structure shall be backfilled using clean well graded granular material that meets the requirements of AASHTO

M 145 for soil classifications A-1, A-2 or A-3.

Backfill must be placed symmetrically on each side of the structure in 6 to 8 inch lifts. Each lift shall be compacted to a minimum of 90 percent density per AASHTO T 99.

Note: Construction loads that exceed highway load limits are not allowed on the structure without approval from the Contracting Officer.
