Inspecting Crossing Surface Panels

Crossing surface panels wear over time due to
many factors
:
  • Truck traffic.
  • Train traffic.
  • Presence of humped or dipped crossing.
  • Soil conditions.
  • Lack of base material.
  • Drainage
    issues
    .
Typical crossing surface panels may last from seven to 15 years depending on various conditions but can last for shorter periods of time in particularly harsh environments. Before deciding to replace a crossing surface panel, consider the following:
  • Does the entire surface need to be replaced or only portions with obvious wear?
  • Are panels rocking? If so, are trucks snagging the edges of the field panels due to a humped crossing condition?
  • Is the crossing draining properly so existing soil is not settling under the crossing?
  • Would changes to the material or thickness of material under the subballast improve the crossing?
  • Would a different crossing material work better than the existing
    material
     based on the truck traffic and climate?
  • What can be done on the crossing approaches to smooth the crossing?
These factors should be considered in
determining
 if the replanking program should be used or supplemented as a means to improve the crossing surface. The railroad company has final authority in determining if a crossing can be repaired or a full replacement is needed.
