The force model of pavement structure is established. In order to investigate the force on pavement when the ratio and thickness of cold recycled pavement vary, three concrete pavement structures, material parameters and vehicle load parameters are designed. By finite element analysis, type 2 pavement structure make the cold-regenerative pavement structure anti-XY surface shear stress, anti-Z compressive stress and anti-Z deformation three aspects are kept in a reasonable range, and it is considered that the cold regenerative pavement structure type 2 is the best. Type 2 is specifically composed of 8 cm new asphalt surface layer +20 cm no stabilized soil regeneration base +20 cm stabilized soil regeneration base + original road soil base. The results of this paper can provide some reference for the actual design of emulsified asphalt cold regeneration construction process.
