Axle weight and vehicle weight aren't the same (or even very closely correlated). A bus will weight ~3-4x more than a car, but has wider tires, and carrying far more people. As such the weight of a bus is likely similar to or lower than an equivalent number of cars.

Here in Seattle, the busy roads with older lanes used for buses are obvious, because they have two deep canyons while the lane next to them is fine. In fact King County Metro has to pay millions in fines to the state because the buses are excessively heavy.
No roads without bus traffic have the same type of damage.

Which is part of the reason to know that axle weight alone isn't a sufficient scale. If you connect 2 cars axle to axle, they won't start doing 8x as much damage. What matters is axle weight divided by tire width.
