COMPOSITE RAILROAD TIES WITH OPTIONAL INTEGRAL CONDUIT
摘要
Railroad ties (2) may be refurbished or have their usable life extended by overwrapping with fibrous reinforcement (4) containing a cured matrix associated with the fibers. The ties may be machined prior to overwrapping, and are preferably sawn along their length, and conduit (5) inserted into channels (9) machined therein prior to adhesively bonding the sawn portions together. The conduits (5) may be used to provide signal and power cable passages with lessened likelihood of damage thereto.
