Fatigue and Creep Crack Growth in Fine Sand Asphalt Materials

CODEN: JTEVAB

Abstract

Fatigue and creep crack growth experiments in sand asphalt specimens have been performed in four-point beading and center cracked tensile setups. Specimen thickness, frequency, and R values were varied. Most of the tests were constant load experiments, but a constant ΔK experiment was also performed.

It was found that Paris law matches the results. Specimen thickness does not affect the results. Results of tests at different frequencies can be reduced to a single scatter band by plotting da/dt(= f · da/dN) instead of da/dN versus ΔK. Different R values can be brought together by a parabolic crack closure relation. It is concluded that the dominant cause of crack growth in this type of asphalt, under the investigated circumstances, is creep.
