| Summary: | The size, geometry, and weight of farm equipment known as implements of husbandry (IoH) have increased and changed significantly to meet the needs of the modern agricultural industry. While intended primarily for use on the farm or in the field, IoH frequently travel on roads and bridges. A review of the history of bridge design vehicles and the evolution of truck size and weight legislation clearly shows that the growth of IoH has exceeded legal vehicles. Bridges are designed based on AASHTO live loads that are different from IoH. Therefore, research was needed to provide guidance to help bridge owners and engineers load rate bridges for IoH in order to both ensure public safety and preserve bridges. Research was performed under NCHRP Project 12-110 by E&T Consulting Engineers to (1) propose new IoH load rating provisions for the AASHTO Manual for Bridge Evaluation (load factor rating "LFR" and load and resistance factor rating "LRFR") and (2) develop a set of protocols to evaluate IoH with various configurations for load rating and overload permits. |
