Title: Long-term performance evaluation of wood fibre fills. Final report

Abstract

The paper presents the results of a research project to determine the long-term performance of wood fiber embankments, that were constructed by the Washington State Department of Transportation (WSDOT) beginning in 1972. At the time of their construction, concern existed that wood fiber fills would only provide a 15 to 20 year service life. Performance of existing wood fiber fills was evaluated based on the quality of the wood fiber material, quality of the effluent, and condition of the pavement. A visual classification system rating the wood fiber from fresh to completely decomposed was developed and used in order to establish a criteria from which all wood fiber material could be rated. Visual examination in conjunction with laboratory tests were used as determining aspects for the effluent quality. The WSDOT Pavement Management System was used to evaluate relative pavement performance. Site descriptions are presented giving specific characteristics and properties of the fills inventoried. An analysis of this information was done to determine the effectiveness of the fills. Over half the wood fiber samples were found to be nearly fresh or fresh and none were found to be completely decomposed. In all but one case, the pavement quality over the woodmore » fiber fills surpassed the comparative highway segment rating indicating the wood fill's performance exceeded that of the surrounding area.« less
