STATUS: Active-FHWA

ANTICIPATED COMPLETION: 12/30/2012

PROJECT OBJECTIVES:

  • Define and compare thin lift overlay maintenance mixes and surface treatments currently used in the New England States.

  • Evaluate the thin lift overlay maintenance mixes and surface treatments currently used in the New England States and compare to those currently used worldwide.
  • Determine the current New England DOT procedures for picking rehabilitation methodologies.
  • Perform and evaluate non-destructive testing to better determine the optimum time to apply surface treatments or thin lift overlay mixes to the existing pavements in order to properly prioritize rehabilitation projects.
  • Evaluate the benefits and drawbacks of using PMA thin lift mixes versus surface treatments with lab testing.
  • Evaluate the cost comparisons between PMA thin lift mixes and surface treatments.
