Abstract:

The basic concepts and the development of a high-strength stabilized-base (HSSB) thickness design procedure are presented. Cement-aggregate mixtures and pozzolanic-stabilized substances are typical HSSB materials. The proposed procedure is based on resilient soil and material testing procedures, the ILLI-PAVE stress-dependent modulus structural model, and design algorithms developed from an extensive ILLI-PAVE HSSB pavement response (stress, strain, deflection) data base. Required inputs are subgrade resilient modulus (E sub Ri, ksi), HSSB modulus (E, ksi), asphalt concrete (AC) thickness (T sub AC, in.) and modulus (E sub AC, ksi), HSSB Design Compressive Strength (psi), and HSSB thickness (T, in.). The AC modulus and the HSSB modulus are used to convert the AC thickness (T sub AC) to an equivalent HSSB thickness. The thickness design criterion is FATIGUE of the HSSB pavement layer. The HSSB FATIGUE relation is based on the HSSB stress ratio, which is equal to HSSB design flexural stress/HSSB flexural strength. Traffic is considered in terms of 18-k equivalent single-axle loads (SAL). Simplified design charts are presented for routine HSSB design.
