Concrete Pipe Strength Evaluation 1

[WARose]

I got a buried concrete (storm water) drain pipe that I am trying to figure if it is ok to run a heavy load across. I have the Concrete Pipe Design Manual and it is clear how to get the loads. I just don't get how to figure the strength. It appears there are "classes".....but I don't see a corresponding load to each class (at least within the manual, I have seen it elsewhere). Does anyone know how to figure what these pipes are good for? Thanks.

If the cover depth is bigger than 10 ft (3 meters) the live load is insignificant (ACPA manual - 2011 ed - Table 42.Notes)
