The axel-weight is the important factor in road damage and large trucks.
The road platform is actually made of sheets of concrete about 12'x
20'(Rough Guess). Your car may place a total weight of 2-3000 lb. on
this slab where a truck may place up-to 20-30000 lb on the slab. The
extreme weight may cause:
The roadbed to sink and/or breakage of the slab.
Don't overload your truck!
Have a good semester break from those of us on the quarter system!
