NETC PROJECT 03-6

PROJECT TITLE: Fix It First: Utilizing the Seismic Property Analyzer and MMLS to Develop Guidelines for the Use of Polymer Modified Thin Lift HMA vs. Surface Treatments

PRINCIPAL INVESTIGATOR(S): Walaa S. Mogawer, PI, UMass Dartmouth; Jo Sias Daniel, Co-PI, University of New Hampshire

PI Email: wmogawer@umassd.edu ; jo.daniel@unh.edu

STATUS: Agreement extension pending

ANTICIPATED COMPLETION: To be determined

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.
