Other than the difference on total applied load, what is the main differece between the two loads? When is more approppriate to apply one or the other?

HL-93 is an HS-20 truck (4T axle and 2-16T axles, usually spaced at 14') with a 640 plf lane load. This is a bridge loading, which is also applicable to box culverts. In NY there are certain instances where we neglect the lane loading on box culverts and manholes. I'm not sure what others do for a buried pipe with regard to lane load but it seems like an overkill.
