No full textThe term “Self-healing materials” refers to materials that are capable of fully or partially repairing themselves when they experience damage with a local or global functionality loss. Local functionality loss occurs when a section of a material or structure exhibits degraded performance when compared with the rest of the material. Global functionality loss occurs when the material or structure exhibits degraded performance compared to its performance prior to any exposure to operational actions
Evaluation of healing potential of bituminous binders using a viscoelastic continuum damage approach
Full text linkA simplified viscoelastic continuum damage model was adopted to analyze experimental data obtained
from healing tests consisting of continuous shear loading interrupted by single rest periods. Tests were
conducted on various bituminous binders with the purpose of highlighting the aptitude of the proposed
methodology in discriminating and ranking their healing potential. Healing was quantitatively assessed
by introducing two indicators (HRC and HRS) derived from damage characteristic functions. Results
revealed the existence of some irreversible damage after continuous shear loading. In addition, even
though polymer modification enhances healing properties of base bitumen, in some cases neat binders
may outperform polymer-modified binders
