AXLE LOAD SURVEYS
Axle
A shaft on or with which a pair of wheels revolve.
,Axle load
The total weight of a wheeled vehicle which is felt
by the road for all wheels connected to a given axle
It is the fraction of total vehicle weight resting on a
given axle.
Axle load is an important design consideration in
the engineering design of roadways as they are
designed to tolerate a maximum weight per axle.
Exceeding that set maximum load causes damage
to roadways.
An accurate estimate of existing/current traffic
loading is essential for an appropriate pavement
design.
Current vehicle loads can be determined by an
axle load survey. Usually done for heavy vehicles.
,Ways of measuring axle loads
Fixed weigh bridge
Portable weigh pads
Weigh in motion equipment
, Permanent weighbridges
Permanent weighbridges are large, fixed weighing
platforms used for vehicle and axle load regulation
and certification. They are usually located at
purpose-built sites on the main arterial routes of a
network and are often operated by a Government
department.
