Investigation of the Effects of Superheavy Loads on Pavements

---

The Texas Department of Transportation has been issuing permits for movement of superheavy loads on an ever-increasing basis. By definition, the Department classifies gross vehicle weights in excess of 250,000 lbs. (113,400 kg) as superheavy loads. Occasionally, superheavy loads have exceeded 1,000,000 lbs. (453,600 kg), and in some instances, 2,000,000 lbs. (907,200 kg). The effects of superheavy loads on pavements are not established at the present time. This paper illustrates a preliminary procedure for evaluating proposed superheavy load routes. The procedure developed may be used to identify weak sections along a route where temporary strengthening measures are needed to prevent overstressing of the pavement. Alternatively, recommendations can be made with respect to modifying the trailer configuration such that the predicted stresses under load are reduced to levels that will not exceed the strength of the subgrade.
