Using two-way ANOVA and hypothesis test in evaluating crumb rubber modification (CRM) agitation effects on rheological properties of bitumen

► Low shear blended samples are more resistant to fatigue cracking. ► The ANOVA and hypothesis test are used for evaluation of CRM binders properties. ► Blending conditions have superior effect on LT, IT and HT performances. ► Dynamic viscosity of modified binders is more sensitive to CR contents.
