Evaluation Of The Degree Of Blending Of Reclaimed Asphalt Pavement (Rap) Binder For Warm Mix Asphalt, Luis Gaitan
Evaluation Of The Degree Of Blending Of Reclaimed Asphalt Pavement (Rap) Binder For Warm Mix Asphalt, Luis Gaitan
Theses and Dissertations
The paving industry in recent years has seen the emergence of a plethora of warm mix asphalt (WMA) technologies and application. With most states incorporating a recycled asphalt pavement (RAP) limit, it is necessary for WMA to not only serve as a greener technology but to work in conjunction with current RAP practices. Presently, most agencies assume a full blending condition in their mixtures which may lead to under asphalted mixtures. The purpose of this study is to develop a methodology for quantifying the degree of blending that occurs in WMA RAP mixtures at higher percentages of RAP. In addition …

Theses and Dissertations
When old roads have to be replaced, the existing pavement, known as Reclaimed Asphalt Pavement (RAP) is ripped up, milled, and stockpiled and can be used in the creation of new mixes in order to save money and resources. New Jersey state specifications limit the percentage of RAP that can be used to 15% for surface courses and 25% for the intermediate and base courses; however, other states have implemented much higher RAP percentages. The limitations are placed because the interaction between the virgin and residual RAP binder is unknown, with respect to the amount of residual binder that is …
