Theyse, HL2009-01-302009-01-302002-02Theyse, HL. 2002. Subgrade design models. STEP Report, STEP-TIJ68, pp 2http://hdl.handle.net/10204/2945Masters Degree Thesis: HL Theyse - The development of mechanistic-empirical permanent subgrade deformation models from heavy vehicle simulator data. The work was aimed at improving the accuracy of one of the components of a flexible pavement design procedure commonly used in South Africa, namely the South African Mechanistic-Empirical Design Method (SAMDM). This was achieved through the development of a new design approach and permanent deformation model for the pavement subgrade. The new distress model for the pavement subgrade was developed from a comprehensive Accelerated Pavement Testing (APT) database on subgrade behaviour and permanent deformation that was generated by a fleet of Heavy Vehicle Simulators (HVSs) over 20 years of testing in South Africa.enMechanistic empirical pavement designPermanent subgrade deformationSubgrade vertical strainSubgrade elastic deflectionSubgrade bearing capacityReportTheyse, H.
