With rapid growth and development of urban cities, rural areas have become primary focus for setting up industrial plants. Depending on the type of facility, major components may be fabricated at a fabrication plant in the City and then moved to the plant location. Occasionally, these components are considered to be superheavy and organizing a secure and successful move from the fabrication plant to the final location becomes a necessity. There have been multiple research attempts to develop structural response models to predict pavement damage from superheavy loads. This paper is an update to a 2016 TAC paper “Modelling Pavement Response to Superheavy Load Movement” in which outcome of several studies of superheavy load moves planned for the spring and winter months were discussed. This paper expands the research on the transport vehicle that was studied for a winter move. The transport vehicle for the winter move comprised a double inter combi trailer with gross weight of vehicle of approximately 1.5 million kilograms. This vehicle had two 24 axle line trailers with 1.5 m axle spacing. Due to the sophisticated nature of the project, and various shortcomings highlighted with previous research methods, finite element modelling was used to determine the pavement layer stresses and strains when subjected to superheavy load moves. To facilitate the move, several trials were completed with various scenarios. The move was successfully completed on the first week of January 2019. This paper will summarize the methodology and results of various scenarios predicted and pavement inspection result prior to and after the move.
