The paper shows how to develop EALF of ten axles 80 tires trailer on flexible pavement structures, which is used to transport segmented concrete girder from fabricator site to project site. Total maximum weight is 175 tons. Trailer is operated between 10 pm - 4.30 am to minimize traffic obstruction. EALF analysis is based on mechanistic empirical method. As air temperature affects modulus of surface layer, Bandung's average minimum temperature is used. The result shows fatigue criterion determined its failure on pavement with high subgrade modulus, otherwise its failure criterion is based on permanent deformation. Thicker pavement has higher EALF when its failure is permanent deformation, otherwise EALF is lower. In general, EALF is within a range of 3.28 to 78.44. The higher the subgrade modulus, the lower trailer's EALF. Trailer's EALFs for subgrade modulus of 50 MPa is higher than subgrade moduli of 100 - 150 MPa. The difference is apparent with surface thickness of 150 - 200 mm.
