- Abstract
Reinforcement with waste tires is an emerging method for enhancing the performance of road subgrades. To investigate the effect of tire burial depth on performance of subgrade, a numerical model was established using FLAC3D to simulate and analyze settlement, soil pressure distribution, and maximum stress within the tires in the subgrade. The subgrade soil was characterized using a nonlinear elastoplastic constitutive model that incorporates a hyperbolic stress-strain relationship and the Mohr-Coulomb failure criterion. The waste tires were characterized using linearly elastic liner elements. Results indicate that the waste tire reinforcement effectively reduces the subgrade settlement, and this reduction effect becomes more pronounced as tire burial depth decreases. Tire reinforcement reduces the maximum soil pressure in the subgrade and spreads the soil pressure to a broader area, resulting in a more even distribution of soil pressure. The maximum stress within the tires decreases with increasing burial depth and exhibits a nonlinear relationship. Results provide valuable insights for the design and engineering application of waste tire-reinforced subgrade.
