Abstract:

This paper investigated the damage healing, local life compensation and intrinsic healing characteristics of asphalt binder. The damage healing (Delta S) is independent of damage level and the percent local life compensation (%Delta N) increases with a higher strain amplitude in TSH test. The integrated Delta S-Delta N analysis is recommended for the healing compensation characterization. The totally stored pseudo strain energy (PSE) to counteract healing recovery is linearly linked to the Delta S regardless of the loading modes, strain amplitudes and rest periods. A new parameter of average stored PSE (QH) is proposed to reveal the intrinsic healing potential and characteristics.
