Characterizing blending efficiency of plant produced asphalt …
15/11/2016 · One new approach was proposed for evaluating the blending efficiency of plant-produced recycled asphalt mixtures when virgin and RAP aggregates cannot be separated from each other. The blending efficiency of three mixes including one warm mix, two hot mixes with or without rejuvenator, were used to validate the method.
1/8/2019 · A total of 14 plant-produced asphalt mixtures were tested for their RAP/RAS binder mobilization rate using fluorescence microscopy and GPC. Linear regression analyses were conducted to evaluate the influence of mixture design and production condition parameters on the mobilization rate.

Recycling efficiency evaluation of asphalt plant | Taylor & Francis …
With the use of high percentage Recycled Asphalt Pavement (RAP), there is an increasing concern over how much of the aged binder in RAP that can be blended into virgin binder. In this study, the RAP binder mobilization rates of nine mixtures from asphalt plants in Tennessee were tested using …
Evaluating Recycling Efficiency of Plant-Asphalt Mixtures …
Abstract. With the continuing increase in the use of recycled asphalt pavement (RAP) and recycled asphalt shingle (RAS) for highway construction, there is a concern over how much of the aged asphalt binder inside RAP/RAS can be blended into virgin asphalt binder. In this study, the RAP/RAS binder mobilization rates of 13 different mixtures produced

Blending efficiency evaluation of plant asphalt mixtures using …
In this study, a laboratory procedure was proposed based on fluorescence microscopy for quantifying the mobilization rate of aged binder in plant-produced RAP mixtures. This procedure was derived from the mean gray value of an asphalt-coated aggregate particle.
Blending efficiency evaluation of plant asphalt mixtures using …
10/2/2018 · The blending efficiency is defined as the percentage of the aged asphalt binder in RAP that can be blended into virgin asphalt binder and thus become available to coat aggregate. If RAP binder is not blended with virgin binder, the effective asphalt content in a mixture would be lower than its design asphalt content and the mixture performance be compromised.
