The University of Massachusetts at Dartmouth has concluded a study of high-polymer content thin lift mixtures containing up to 40 percent RAP.
Initially, the study planned to test materials from Massachusetts and New Hampshire. After preliminary testing, Massachusetts withdrew from the study and Minnesota, Oregon, Vermont, and New Jersey were added.
Final test results and project descriptions are now available.
Preliminary test results for mixes containing Massachusetts materials can be viewed here.
New Hampshire DOT and the Vermont Agency of Transportation have tested applications of Highly Modified Asphalt (HiMA) thin lift overlays and incorporated their comments into a short (3m42s) video.
