Soil engineering for highway design

Soil engineering is a part of geotechnical engineering that deals with the characteristics of soil. It also helps to understand the behavior of the soil in different conditions. The basic concepts of soil are studied to check the strength, compressibility, and porosity of the soil. This makes soil engineering an important topic for civil engineering.

Question

Calculate the Equivalent Axle Load Factor (EALF) and Vehicle Damaged Factor (VDF) in axle
load survey. The axles of a sample of about 10% of randomly chosen trucks equivalent to 250
are weighed using axle load pads, different configurations of axle loads are represented in the
sample. Axle load are in tons

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)
