The aim of this research project was to improve current practice by investigating different test methods to quantify moisture damage in an effort to serve the short and long term needs of the agency and industry. In the ...

This research study was conducted to determine the influence of maximum aggregate size, lift thickness, and aggregate source on the density and permeability of asphalt mixtures designed according to the Superpave criteria. ...

In June 2005, a report with Modified Binder Selection Guidelines for Wisconsin was finished under the sponsorship of the Wisconsin Highway Research Program. The report name is Development of Guidelines for PG Binder Selection ...

The objectives of this study were to (1) evaluate the effect of compaction effort and temperature on densification of HMA in the field and in the lab, (2) quantify the effects of Warm Mix additives on the compaction, and ...

The purpose of this study was to look at the effect of lift thickness as it relates to the density of Superpave Hot Mix Asphalts. The study consisted of two phases: (1) a laboratory study and (2) a field study. In the ...

In 1997, the Wisconsin DOT made the transition to use PG binders in place of the Penetration and Viscosity graded asphalts that had been historically used. The decision at that time to specify the PG 58-28 as the standard ...

In this study several asphalt mixtures were produced using four different aggregate sources, different asphalt contents, and different aggregate gradations. Every mixture was compacted using the Superpave gyratory compactor ...

The Wisconsin Highway Research Program (WHRP) Steering Committee commissioned an implementation pilot program in 2006 to facilitate the incorporation of research results into the programs, standards, and processes of the ...

The objectives of this study were to evaluate the relationship between the performance of asphalt pavements in the field and the Tensile Strength Ratio (TSR) values measured in the laboratory on the original asphalt mixtures ...

The Wisconsin Department of Transportation (WisDOT) has implemented the Superpave recommendations in the 2000 Supplemental Specifications. This research was directed towards better understanding of the influence of ...
