WB-67 Axle Loading

[RDR89]

Hi all, was wondering if anyone has come across WB-67 axle loading? I can only find the overall loading, which isn't terribly different from HS20 but wanted to see if anyone had reference info.

WB-67 is combination truck Interstate semitrailer (WB-67) with sizes 13.5H, 8.5W, 73.5L and AFAIK , is used for geometric desing of highways ( Turning radius , etc) .

You are expected to look AASHTO Standard Spec. design truck loadings.
