Traffic

in Passes
Restrictions on Use as Design Criteria
200
CBR and thickness requirements shown in table B-2 may be
used without restriction for the
Shoremaster, Clark 512, Belotti B67b, Hyster H620B, Lancer 3500, P&M 6250-TC, and M52
tractor-trailer.
CBR and thickness requirements given in table B-2 may be used if necessary and identified as
"tentative criteria" for the LARC LX, LeTro-Porter 2582, and Travelift CH 1150.
CBR and thickness requirements given for the LeTro Crane GC-500 shall not be used for criteria
in any case except under emergency conditions. The reliability of these requirements is
unknown.
10,000
Basic test data for operations of vehicles on unsurfaced soils are limited in scope to data from
traffic volumes of less than about 5,000 passes. The reliability of requirements developed by
extrapolation for volumes beyond the limits of basic test data is questionable. The thickness and
CBR requirements shown in table B-2 for 10,000 passes shall not be used for criteria except
under emergency conditions.
