Axle overloading at the southern part of the North-South Expressway in Malaysia

Abstract

Overloaded vehicles may cause excessive wearing and damages to pavements, roads and bridges. They also threaten the road safety and contribute to several fatal accidents, thus the governments around the world have implemented axle load limitations. This paper investigates the overloading level at the southern part of North-South Expressway in Malaysia. The data were gathered from three survey stations located along the southern part of North-South Expressway for a period of one year. It was found that overloaded axles form a considerable percentage of the total volume. It has been recommended that enforcement level of axle load limitations along the southern part of North-South Expressway should be increased. © 2012 IEEE.
