Title: Development of Recommendations for Compaction Temperatures in the Field to Achieve Density and Limit As-Built Permeability
PI: Robert Schmitt
Department of Civil Engineering
University of Wisconsin - Platteville
Project: The objectives of this study are to:
(1) Investigate the minimum limiting temperatures at which required density of HMA can be achieved with
commonly used compaction effort;
(2) Investigate the effect of density achieved “as-built” on water and air permeability and measure how density
and permeability (as-built) affect asphalt pavement performance in Wisconsin;
(3) Understand the inter-relations between HMA mixture properties (aggregate gradations and volumetrics),
temperature and in-place density and permeability;
(4) Establish target minimum temperatures that are needed to achieve permeability and density values suitable
for use within contract specifications;
(5) Develop temperature-stress profiles to provide guidelines for field compaction.
(6) Quantify the effects of Warm Mix additives on the minimum temperature and the temperature-stress profiles
