AXLE LOAD SURVEY

Every moving wheel induces dynamic deflections which alternately causes tensile and compressive stresses in the road structure. The damage that vehicles do to a road structure depends greatly on the magnitude of the axle loads.

The success of an axle-load survey and the ease with which it can be carried out will depend very largely on the choice of site. The site must be selected to make it possible to sample the traffic easily and safely.

Axle pad was used to ascertain the load of the axles. Roadside selection method was adopted for the survey. The vehicles were stopped on a random sample basis with the help of Police and loads on the each axle of the vehicle have been measured to estimate the loading pattern of the vehicles on the project road.
