Abstract While many studies have investigated the application of BIM in helping the integration of architectural, construction or manufacturing projects, however, it has been barely used in road engineering due to the lack of pavement structure analysis in the present Road-BIM products. The aim of this research is to develop a framework for the integration of BIM and structure verification to improve the application of BIM in road engineering and thus reduce the mistake and repetition in pavement design. Relying on the capabilities of Dynamo, a three-dimensional road model with pavement controllable parameters was first established. Successful implementation of this step can facilitate the designer with more flexible and convenient needs in design process. Secondly, a subroutine is developed based on Python to combine Dynamo with the Mechanistic-Empirical Pavement Design Guide (MEPDG) which provides the pavement structure analysis. As a response to long-term development between BIM and road engineering, this paper contributes by offering innovative and practical solutions for integration of road design and pavement analysis, which effectively solves the long-existing defect that the pavement structure cannot be analyzed in the environment of BIM, and thus, will significantly promote the further application of BIM technology in the road industry.
