Book excerpt: The Wisconsin Department of Transportation (WisDOT) uses wooden posts to support many types of signs along state highways. WisDOT currently uses red pine or Southern Pine posts treated with chromated copper arsenate (CCA) and has generally experienced satisfactory performance and service life. However, there are some areas of concern, as well as potential opportunities for diversifying the wood species and preservatives used. Warp is sometimes a problem with the current pine posts, and increased use of locally sourced wood species for the sign posts could decrease transportation costs and potentially benefit Wisconsin industries. Although CCA is a highly effective preservative, it may not be the optimum treatment for alternative wood species. This study reviewed the characteristics of alternative wood species and wood preservatives and evaluated their potential for use in Wisconsin highway sign posts. The evaluation concluded that WisDOT's current practice of using red pine or Southern Pine posts treated with CCA is logical and may be the optimum combination of wood species and preservatives currently available. Red pine and Southern Pine are readily available and relatively strong compared with many other softwood species. Red pine is also an important commercial resource for Wisconsin and the upper Midwest. Other Wisconsin species to consider include eastern white pine and soft maples. However, strength may be a concern with eastern white pine, whereas cost may be a concern with soft maples. CCA is an effective preservative, readily treats red pine and Southern Pine, and is compatible with aluminum signs. Copper naphthenate in oil solvent appears to be one of the most logical alternatives to CCA, and would be a strong candidate for treatment of hardwoods. Copper naphthenate is non-corrosive to aluminum and would avoid warp associated with re-drying after treatment with water-based preservatives. WisDOT may want to consider purchasing a small volume of copper naphthenate-treated posts to evaluate the handling characteristics of this oil-based preservative.

This book was released on 2015-06-26 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Wisconsin Department of Transportation (WisDOT) administers approximately 11,800 miles (18,990 km) of state highways (WisDOT 2014). WisDOT uses preservative-treated wood posts for much of the signage along these highways because wood is relatively inexpensive, easy to install, and has the necessary strength properties to tolerate typical Wisconsin wind loads. Although WisDOT's experi-ence with wood sign posts has been generally positive, there are some areas of concern, as well as potential opportunities for diversifying the wood species and preservatives used. WisDOT and the USDA Forest Products Laboratory con-ducted a comprehensive literature review to examine those concerns and opportunities.

Book excerpt: In view of the Virginia Department of Highways and Transportation's need to conserve dwindling revenues, the Traffic Research Advisory Committee recommended that the feasibility of using unpainted, treated wooden sign posts instead of painted posts be investigated. With the subsequent change to the use of unpainted, treated wooden sign posts, the Advisory Committee recommended that the evaluation be extended to compare the target values of painted and unpainted posts. In the evaluation, special attention was focused on residues formed from the chemicals used to treat the post and adverse effects they might have on the legibility and general appearance of the sign panel. The target values of a painted and an unpainted post were observed under different conditions. After 36 months, the retroreflective characteristics of the sign panel mounted on the unpainted, treated wooden sign post had not changed abnormally or significantly. Also no streaking on the sign panel or twisting of the sign post was noted. A comparison of target values of the posts showed the painted post to be more visible at times; the difference was minimal and can be made inconsequential by using reflectors on the posts. The Department's decision to use unpainted, treated wooden sign posts was reconfirmed by the results of the evaluation.
