3.13 Aluminum Composite Permanent Sign Substrate

3.13.1 This specification covers the use of aluminum composite panels as a substrate for permanent traffic signs as an alternative to conventional permanent sign substrates such as solid aluminum and plywood.

3.13.2 Technical: This composite sign material must be manufactured by bonding two skins of aluminum to an extruded polyethylene core utilizing a thermoset adhesive under tension and pressure in a continuous process. The polyethylene core must be pigmented with carbon black to prevent core edge deterioration from UV exposure. The resulting composite product should be light, exceptionally flat, strong, rigid, and resistant to breakage. It must fabricate similarly to aluminum and enable operations such as sawing, shearing, drilling, and punching. The exterior coating must be either a polyester paint that provides a surface quality that is suitable for the proper adhesion of reflective sheeting or Alodine® conversion coating.

Documented evidence that the material is an approved substrate by the major reflective sheeting manufacturers must be provided. The interior coating of the aluminum skin must be coated with an epoxy chromate primer for added bonding strength with the polyethylene. The sign blank must be capable of being exposed to temperature ranges of –60 degrees F to +170 degrees F. The material must be available in thickness of 2mm, 3mm and 4mm and in widths of 36”, 48” and 60” and in aluminum thicknesses of .010” and .020”. The edges must be provided straight without displacement or projection of the core or skin. The name of the product must be identified on at least one side of the sign blank. When it becomes desirable to remove the reflective sheeting from a finished composite sign, and reclaim the sign blank, the composite material must have the properties to be processed through a conventional sheeting removal system like the Hydrostripper high pressure water unit without any consequence for its reuse.

* Testing: This product shall have undergone documented wind testing. 48”x48” signs mounted on steel 2 ½” x 2 ½” square permanent posts shall be tested using turbulent flow equipment with a minimum sustained velocity of 80 mph (with minimum 108 mph gusts). The flow pattern of the wind equipment shall be calibrated in 2’x2’ square flow areas prior the testing and must be within 10% of the 80 mph and 108 mph minimums over the area of the sign(s) to be tested.

Each sign tested must use one of the types of retroreflective sheeting listed in Table 1. At a minimum, a 2mm thick sign with the .010” minimum aluminum thickness and a 4mm thick sign with both the .010” minimum and the .020” maximum aluminum thickness shall be tested. Video and digital image documentation and physical measurement of the substrate behavior under various turbulent flow wind loads must be observed by an Independent Testing Agency. The specific wind testing shall be a minimum of 15 minutes duration from each on the front of the sign and then 15 minutes on the back of the sign with the sign attachment to the post not being disturbed between the two tests.

Every three minutes of each 15-minute test the wind velocity shall be increased to minimum of 108 mph for a minimum of 10 seconds. In all there shall be a minimum of five 108 mph gusts on each side of the sign. The signs shall be mounted in the square orientation rather than diamond. The sign will be mounted via two 5/16” sign mounting bolts with 7/8” diameter, 1/8” thick nylon washers on the centerline of the sign. The sign deflections and residual deformations shall not exceed the values in Table 1 below. The deflections and deformations shall be measured no more than 1 1/2” vertically or horizontally from the midpoint of one or both vertical edges of the sign by a real-time linear transducer/data acquisition system. If the sign should bow in the vertical direction rather than the horizontal direction when the wind is on the back of the sign, then the results reported must call attention to that occurrence since it will be misleading as to the general performance of the material. In that case, the data taken from the wind impacting the front of the sign shall be used to determine whether the material meets specifications. The material supplier must provide the test date(s), the name of the facility, and the name of the independent testing agency.

*Residual Deformation is the difference in the position of the linear transducer attachment point after each 15-minute run when the wind has ceased compared to the initial position before the run.

3.13.3 Recycling: The material must be able to be recycled through a process defined by the manufacturer or supplier to reclaim a defined percentage of aluminum and polyethylene.

3.13.4 Manufacturing Quality System: The aluminum composite manufacturing facility or facilities must present documentation to show they are at least ISO 9001:2000 certified to produce the laminates specified herein.

3.13.5 Warranty: Warranty must be provided against defects, workmanship, and failures for the expected effective life of the reflective sheeting.

3.13.6 Packaging: Standard packaging for blanks to be 4-way skid or special wooden reinforced box/skid. Standard packaging quantity depends on size of the order.

Bulk packaging per request. All packaging per industry standard.

3.13.7 Technical Support/Training: Supplier must provide personal factory support, and training within 24 hours for product matters that relate to fabrication and applications.

3.13.8 Sample: Non-returnable samples may be required at no expense to evaluate prior to an award.

3.13.9 Any requested deviation from these mandatory specifications must be submitted as a question prior to the question deadline for consideration. Responses to vendor questions shall be published as an addendum on wvOASIS.
