This project is expected to result in a proposal for a mechanistic-based design equation and localized LRFD resistance factors. The overall objective of the project is to provide guidance for future designs of drilled shafts in New Mexico.
New Mexico Pavement Life Expectancy - NM08MNT-02 View Project Summary
Objectives of this project are as follows: a. 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. b. 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. c. Determine the optimal perpetual pavement structure using the mechanistic-empirical design approach to develop and evaluate design alternatives based on pavement stiffness and thickness. d. Quantify the impact of removing layers, and considering various degrees of bonding within a perpetual pavement section. e. Document the literature, analysis, findings and recommendations for perpetual pavement methods and guidelines for consideration to be incorporated into the current NMDOT perpetual pavement design.

The research reported herein evaluates the possibility of replacement of the current method of R-Value estimation used in the preparation of subgrade and base course materials. This research was conducted by measuring stiffness values of said subgrade or base course using three candidate devices: the Clegg Impact Hammer, the GeoGauge, and a Dynamic Cone Penetrometer. The stiffness values were then correlated with laboratory determined R-Values of the same material to find a mathematical relationship with the candidate devices.
