AB  - Despite the growing popularity of alternative transport networks, road transport remains the dominant method for transporting goods and equipment. In order to remain competitive, the allowable mass limits of heavy vehicles are regularly increasing, enabling them to distribute more products per shipment. As heavy vehicles travel over the road surface, a complex dynamic interaction occurs, generating dynamic loads through the tyres and imparting these loads onto the pavements they traverse. Generally, the increased mass limits result in higher dynamic forces being exerted on pavements. These excessive dynamic loads can lead to rapid pavement deterioration, reducing the expected life of roads, and increasing the frequency of maintenance. In order to predict the dynamic tyre forces generated by these heavy vehicles, road elevation profiles (measured or syn-thesised) are used with vehicle dynamic models. The current approaches for simulating road profiles are, however, not adequate to excite the actual vehicle modes of vibration during transport; namely the heave, pitch, and roll motions. This paper presents a numerical investigation into the use of improved pavement elevation profiles and their influence on the dynamic tyre forces exerted by heavy vehicles. A complete four-wheeled heavy vehicle multibody model was developed using the in-house developed EasyDyn library, and simulated to travel over numerous road elevation profiles synthesised using MatLab. A comparison between the various profiles is presented, demonstrating their influence on the generated dynamic tyre forces.
