Load Rating—live load carrying capacity of a bridge. Load Rating Method, Allowable Stress Rating (ASR)—limits capacity to an allowable stress. Dead loads are unfactored, and live loads are factored with impact. In Florida, ASR load ratings use the HS20 Design Load. ASR follows AASHTO Standard Specifications for Highway Bridges, and MBE Part B. with the Structures Manual (Topic No. ).
