Bridge Load Rating of a Super Load using AASHTO LRFR
This project is a good case study of an oversize vehicle rating of bridges that is beyond the usual scope of most, if not all, state departments of transportation. This presentation/paper will address the challenges faced, while presenting the methods and procedures used to handle the project. The project involve rating over 50 bridges in total for a specially fabricated super overload vehicle weighing over 715 tons transporting a steam generator from California to Utah. The vehicle consists of more than 33 axles, with each axle weighing 51,000 lbs. AASHTO Load and Resistance Factor Rating (AASHTO, 2008) procedure was utilized, with slight modification to several factors in accordance to California Department of Transportation. The unique challenge for the project was safely and efficiently moves the oversized vehicle. The route chosen for the move consists of some old bridges build between 1940's to 1980's, as well as some new bridges recently builds. With the mixture of new and older bridges, creative analytical methods were employed in order to account for the variation in steel used (Grade 40 versus Grade 60), concrete curing differential, and other factors to be discussed in detail.
