Effect of reclaimed asphalt shingles addition on asphalt concrete dynamic modulus master curves
The paper presents the comparison of dynamic modulus and phase lag in different loading conditions for asphalt concrete mixture with or without reclaimed asphalt shingles (RAS) addition. For each mixture, 6 samples were tested using the four point bending beam method, at four temperatures and at six...

| description | The paper presents the comparison of dynamic modulus and phase lag in different loading conditions for asphalt concrete mixture with or without reclaimed asphalt shingles (RAS) addition. For each mixture, 6 samples were tested using the four point bending beam method, at four temperatures and at six frequencies. The results of the study were subjected to the analysis of the statistical significance of differences between mixtures. The graphic form of results presentation includes Black curves and Cole-Cole plots. Then, matching the sigmoidal functions enabled the creation of master curves of the complex stiffness module and the phase shift angle, being a function of the load frequency. It has been observed that the mixture with the addition of RAS has higher stiffness and elasticity in the range of higher temperatures (20°C and 30°C) and lower load frequencies, which results in higher values of the complex stiffness module and lower values of the phase lag. At 0°C, the behavior of both mixtures is very similar, while at 10°C significant differences between the tested mixtures were found only for low frequency loads (up to 5 Hz). Test results have shown that mixtures with the addition of RAS have a lower thermal sensitivity in terms of the complex stiffness modulus and phase lag than the reference mixture. The above results confirmed an improvement in rutting resistance for RAS mixes observed in previous work. |
