Phase 4 Study and Evaluation of Materials Response in Hot Mix Asphalt Based on Field Instrumentation

The instrumented pavement section at Interstate I-40, near Albuquerque, New Mexico (Dist. 3), has provided the stress-strain data needed to fully implement the pavement mechanistic-empirical design (PMED) software in New Mexico. The Phase III study recommended considering additional instrumentation sections under different structural types, weather patterns, and loadings. As the I-40 pavement section can still provide valuable pavement design and material response data, Phase IV is proposed to continue data collection using this instrumented section.
