Development and Validation of a Unified Equation for Drilled Shaft Foundation Design in New Mexico

The objectives of this project are to: (1) assess current design, testing, and evaluation methods of perpetual pavements, with particular emphasis on their applicability to the design of perpetual pavements with a design life of fifty (50) or more years in conditions typical of New Mexico pavements, materials and environments; (2) evaluate the effects of moisture infiltration on the current perpetual pavement performance considering reduction in stiffness and strength properties of Hot Mix Asphalt (HMA) and pavement foundation layers; (3) determine the optimal perpetual pavement structure using the mechanistic-empirical design approach to develop and evaluate design alternatives based on pavement stiffness and thickness; (4) quantify the impact of removing layers, and considering various degrees of bonding within a perpetual pavement section; and (5) document the literature, analysis, findings and recommendations for perpetual pavement methods and guidelines for consideration to be incorporated into the current New Mexico Department of Transportation (NMDOT) perpetual pavement design
