  • Abstract:
    Problem: Perpetual asphalt concrete (AC) and long-lasting Portland cement concrete (PCC) pavements are relatively new to the pavement community. These newer pavements require the use of innovative Mechanistic-Empirical (ME) design procedures, advanced climatic models, updated specifications, test methods providing detailed material properties, and construction techniques not been entirely adopted into standard practice. Standard practice for rehabilitating distressed highway pavements generally involves the application of AC overlays. When AC overlays are placed on distressed PCC pavements, slab movements cause stress concentrations to develop at joints and cracks, which often results in premature cracks reflecting up through to the surface at these locations. By breaking PCC slabs into smaller pieces prior to overlay, stresses are reduced by distributing the load over a wider area. Instrumentation installed in these pavement sections will provide data regarding measured responses under known environmental and loading conditions. Objectives: (1) Monitor new perpetual AC and long-lasting PCC pavements constructed on US-30 in Ohio, rehabilitated PCC pavements on I-86 in New York, and other existing instrumented pavements in both states, (2) Verify ME design procedures for all pavements in the study by comparing theoretical calculations with measured responses and performance, (3) Calibrate ME procedures presented in the NCHRP 1- 37A AASHTO Pavement Guide for Ohio and New York using data collected in this and other previous studies, (4) Conduct controlled testing of perpetual pavement systems to determine their relative performance and to recommend the most promising layer configurations, and (5) Document all research findings in a final report. Within each of these primary objectives were various secondary objectives related to the primary goals.
