• 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.
