Title:

Application of Viscoelastic Continuum Damage Theory on Small Size Specimens to Assess Asphalt Fatigue Performance

Accession Number:

Record Type:

Component

Abstract:

In this paper laboratory fatigue studies of asphalts produced with both unmodified and polymer modified binders were carried out using classical testing geometries and small size specimens. The small size specimen test results demonstrated a high degree of scatter in the measured number of cycles to failure with no clear relationship to the binder used in the asphalt. However, when the data were analysed using a viscoelastic continuum damage approach a good correlation in the predicted fatigue lifetime was found between the small size specimens and full size trapezoidal specimens. These results suggest small size specimens may provide a useful indicator to asphalt fatigue performance requiring significantly less time and material than traditional tests.
