| 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 |
