J. Cent. South Univ. (2017) 24: 360-373 DOI: 10.1007/s11171-017-3438-z Evaluation of rutting performance of stone matrix asphalt mixtures containing warm mix additives Rezvan Babagoli1, Hassan... and modified bituminous binders. In this research, three warm mix additives (Sasobit, Rheofalt and Zycotherm) were used to modify 60-70 penetration grade base binder. The rutting potential of both modified......
by conventional powder metallurgy technique. The effects of Yb2O3 content and sintering temperature on the relative density, phase composition, microstructure of the sintered cermets and the corrosion resistance... by the reaction between Yb2O3 and ceramics. The addition of Yb2O3 accelerates the sintering process of ceramics matrix, eliminates pores in the boundary and results in coarsened crystalline grain. The relative......
