It is experimentally measured that road damage is proportional to fourth power of weight on an axle. And most of the trucks have multiple axles that distribute the weight. But SUVs while being lighter only have 2 axles, so the road damage done isn’t that much smaller. So I wouldn’t be surprised if most of the damage was done by SUVs, since there are much more od them.
