User:Aggienazareth/Traffic loading classification

Aggienazareth (talk) 09:02, 9 June 2009 (UTC)IRC Class AA loading consists of either a tracked vehicle of 70 tonnes or or a wheeled vehicle of 40 tonnes. Normally bridges on National Highways and State Highways are designed for these loadings.

Class A loading consists of a wheel load train composed of a driving vehicle and two trailers of specific axle spacings.This loading is normally adopted on all roads on which permanent bridges are to be constructed.

Class B loading is adopted for temporary structures and for bridges in specified areas.
