Highway Overloading and Countermeasures

The distribution of actual axle load and data of overload were obtained through traffic surveys and tests with the HPS portable wheel load scale. By means of conversion to standard axle load and calculation of accumulated applications of the equivalent axle load, it could be concluded that overloading is one of the most important reasons for the premature failure of cement concrete pavement structures. It is proposed that the influence of overloaded vehicles should be emphasized in pavement structure design, along with suggestions of highway technology, automobile technology, and administration for heavy load highways.
