139 Questionnaires Used in Survey Questionnaire Used with U.S. State Agencies A P P E N D I X D Questionnaire for NCHRP Project 12-110 Proposed New AASHTO Load-Rating Provisions for Implements of Husbandry (IoH) 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. Frequently IoH travel on roads and bridges, although not primarily intended. Through a review of the history of bridge design vehicles as well as the evolution of truck size and weight legislation, it is clear that the growth of IoH has far outpaced legal vehicles. The objectives of this research are to (1) propose new implements of husbandry (IoH) load-rating provisions for the AASHTO Manual for Bridge Evaluation (load factor rating “LFR” and load and resistance factor rating “LRFR”) and related revisions to the AASHTO LRFD Bridge Design Specifications; and (2) develop a set of protocols to evaluate IoH with various configurations for load rating and overload permits. To successfully complete this project, we would be very grateful to receive your response to this questionnaire by December 10, 2016 via e-mail to Dr. Gongkang Fu at etengineers@yahoo.com. Thank you very much for your kind assistance! 1. Do you think that IoH represents a concern to the safety of local roadway bridges in your state? Check yes or no. If yes, please try to indicate whether the following bridge groups probably unsafely carrying heavy IoH loads, and/or add more as appropriate. a. Owner (NBI Item 22): County (02); Town or township (03); City or municipality (04) b. Bridge type (NBI Item 43A,43B): Concrete slab (1,01); Concrete continuous slab (2,01); Steel stringer (3,02); Prestressed concrete stringer (5,02); Timber slab (7,01); Timber stringer (7,02); Prestressed concrete box beam (5,05); Steel culvert (3,19); Concrete culvert (1,19); Concrete continuous culvert (2, 19) c. Add more if applicable: If applicable, please add state as owner, truss as bridge type, year built, and/or design load in the above groups.

Please provide the name, phone, and e-mail of a contact person(s) who is (are) responsible for or familiar with your agency’s weigh-in-motion data collection, maintenance, format, archival, etc. This project particularly needs WIM data possibly having recorded IoH. 4.

Examples of such studies may have produced, but not limited to, measurement data for bridge behavior using strain gages and/or other transducers. 2.

Farm equipment, generally referred to as “implements of husbandry” (IoH), has been considered to be local vehicles on farms that do not use public roads often, if at all. As a result, state and local jurisdictions vary widely in managing IoH. Apparently, the growth of IoH has far outpaced that of other legal highway vehicles, warranting concern with bridge safety.

The TRB National Cooperative Highway Research Program's NCHRP Research Report 951: AASHTO Load Rating Provisions for Implements of Husbandry (1) proposes new IoH load-rating provisions for the AASHTO Manual for Bridge Evaluation in load factor rating and load and resistance factor rating (LRFR), along with related revisions to the AASHTO LRFD Bridge Design Specifications; and (2) develops protocols to evaluate IoH with various configurations for load rating and overload permits.
