Bridge performance is affected by bridge material, bridge system, loading type and other internal and external factors. A moving truck generates a dynamic response which is greater than static because of the interaction between the moving vehicle and bridge structure hence it can accelerate deterioration process of the bridge. To evaluate the influence of the passing truck, structural codes require that static live load is multiplied by dy-namic amplification factor (DAF) or is a built-in value of a live load model. Road surface deterioration of ex-isting bridges influence bridge performance hence DAF from field measurements can be higher than values specified in design codes that target new bridges. The paper presents and discusses a research about traffic load effect on the bridge structure. Results show that uneven pavement condition significantly increases DAF values for low vehicle speed.
