H20 Wheel Load (20K Loading) Trench Panels

Select Below

For loads of up to 20,800 lbs.

H20 wheel loading is specified for areas such as driveways, factory floors, parking lots and off roadway applications subject to occasional vehicular traffic.  The 20K load rating has the same wheel loading as AASHTO H20 of 16,000 lbs. plus a 30% load increase due to impact forces for a total wheel load of 20,800 lbs.  20K loading is not appropriate for areas that are subject to continuous traffic such as streets or highways.
