Influence Of Pavement Type On Near Surface Air Temperature, David Duncan
Influence Of Pavement Type On Near Surface Air Temperature, David Duncan
All Theses
Effects from an Urban Heat Island (UHI) can be detrimental to the world as a whole. This study examines a collection of permeable and conventional pavements in South Carolina to determine how they relate to near surface air temperatures, which is an indicator of the UHI impact of an area. Three locations were used, each with a different selection of pavement type. Permeable and conventional forms of both asphalt and concrete were tested, as were some open graded friction course samples. Air temperatures were measured and recorded from the pavement surface up to an elevation of 60-in.

Evaluation Of Warm Mix Open Graded Friction Course Mixtures, James Wurst
Evaluation Of Warm Mix Open Graded Friction Course Mixtures, James Wurst
All Theses
The goal of this study was to evaluate EvothermTM (a chemical package) and foaming (a water-injection method) warm mix asphalt (WMA) technologies to determine their effectiveness in producing high quality open graded friction course (OGFC) mixes. Specifically, this study focused on the effect of the removal of stabilizing additives (fibers and polymers) on the optimum binder content and performance of WMA OGFC mixtures. By focusing on additive removal, this study attempted to evaluate practical production concerns and the possible benefits of WMA technologies combined with OGFC.
The EvothermTM WMA and foaming WMA mixes were compared to traditional HMA OGFC by …
