This paper describes the effects of stress relaxation on the mechanical behaviour of asphaltic mixtures in ductile zone. Stress relaxation tests were conducted in ductile zone under various loading conditions and examined the effects of stress relaxation on strain at failure, flexural strength and failure envelope of asphaltic mixtures. It is coneluded that strain at failure of asphaltic mixtures increases with stress relaxation of asphaltic mixtures in ductile zone and stress relaxation of asphaltic mixtures have direct effects upon failure behaviour of asphaltic mixtures at various test conditions.
