VDA is the weighted average of the damages caused by the individual axle load group with respect to the
corresponding volume of traffic of each group and is expressed as:
VDF = total no. of standard axles/ no. of trucks
Use the following equations for EALF:
Single Axle Load = ( Axle load in kgs/8160) and for Tandem Axle Load = ( Axle load in kgs/14960)*](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F02fe3222-9df8-4049-a9db-9b9323144b7a%2F694c5f9e-28dd-4fe6-b0a9-86b1ed8f2f51%2Ffrkqws8_processed.jpeg&w=3840&q=75)
