Use of Thermodynamics and Heat Transfer Principles to ...

Use of Thermodynamics and Heat Transfer Principles to Predict Virgin Aggregate Temperature in a Hot-Mix Asphalt Drum Plant. Virgin aggregate is heated and dried in a drum dryer and uses this heated mass to heat and dry reclaimed asphalt pavement (RAP) and/or recycled asphalt shingles (RAS) materials in a drum mixer before blending with virgin asphalt binder.

May 05, 2017  May 05, 2017  For verification purposes, the virgin aggregate temperature is recorded at a drum plant facility, and thermodynamics and heat transfer principles are used to predict the virgin aggregate temperatures. It has been observed that for the HMA mix, the temperature predicted for larger-size virgin aggregate shows good agreement with the recorded value.

Rutting performance prediction of warm mix asphalt ...

It was found that replacing up to 60% of the virgin aggregate with RAP improved rutting properties of the asphalt mixtures because RAP increased asphalt binder's viscosity as a main factor of rutting, especially at high temperatures. However, replacement of too much RAP in asphalt mixtures can increase moisture sensitivity of flexible pavements.

In this study, the influence of the blending degree between virgin and aged binder on the pavement performance of hot-mix recycled asphalt mixture (HMRAM) with high RAP content is analyzed. The aggregate gradation of AC-16 was selected. The RAP contents were 30, 40, and 50%. HMRAMs with different degrees of blending (DOBs) were prepared by changing the mixing temperature (150, 165, and
