Actual truck loads data is vital for bridge rating, and development of bridge design load. In Thailand, bridges have been designed using the HS20-44 design truck according to the AASHTO code; however, the actual truck loads are usually greater than the design truck load from the code. In addition, actual truck load are not available data to develop local truck load model for bridge design. This paper presents truck loads in Thailand that have been monitored using Bridge WeightIn-Motion (BWIM) system which innovated by author. Seven truck types are derived. Nominal analysis for simple span bridges shows that the heaviest Thai trucks induced forces are greater than that of the HS20-44 design truck.
