• Abstract:
  The beneficial use of scrap tire rubber mixed with expansive soils is of interest to civil engineering ; applications since the swell percent and the swell pressure can be potentially reduced with no deleterious ; effect to the shear strength of the mixture. The two main objectives of this research were (1) to propose a ; new subgrade soil stabilization protocol to allow CDOT to rely upon an alternative stabilization method that ; is not subject to the typical problems associated with calcium-based stabilization of sulfate-rich soils, and ; (2) to develop a new database of MEPDG parameters for local soil samples obtained from CDOT and to ; provide advanced testing and analysis of the stiffness degradation of these materials.
