An investigation on vehicle overloading in Muar - Melaka road

Vehicle overloading is considered as one of the most substantial concerns in road transport due to a possible road surface damage. The ability of a pavement structure in carrying out its function reduces in line with the increase of traffic load, especially if there are overloaded heavy vehicle passing through the road. This paper investigates the overloading of vehicles in the Muar-Melaka roads. The main objective of this paper is to examine the percentage of overloading based on types of vehicles and their equivalence factor (EF). Data were collected from fixed weighbridge station by considering gross vehicle weight, maximum permissible gross vehicle and axle load for the period of two years. The result showed that heavy vehicle with 2 axles is the most overloaded vehicle with 74.3%. Besides that, 29% of all heavy vehicles weighted are between 1% to 25% overloading. Equivalence Factor (EF) for this case study area is equal to 3.14. Thus, it is can be noted that EF of this road are still in standard design
