...Honglei Wang; Jianfeng Liu; Hua Qin; Xue Wang; Zhuohui Tao; Shihui Shen Zero shear viscosity (ZSV) has been proven to be a reasonable indicator for characterizing the high-temperature performance of asphalt binders. Various test methods and models have been used in the literature to determine...

... concentration (vol. %) of 0.2, 0.8, and 2 % graphite-EG nanofluid are prepared by ultrasonicating for 5 h. Initially, the effect of temperature variation from 25°C to 60°C (with a difference of every 2.5°C) on the viscosity of prepared nanofluid for different volume concentrations is studied at a fixed shear...

.... This blending caused a reduction in the viscosity of the oil mix as compared to the ISO VG46 oil. Therefore, to bring the viscosity of the blend oil to the level of the ISO VG46 oil, various concentrations of CuO nanoparticles were added to the blend to prepare stable nano-blend oils. The stability of the blend...

...Xue Zhang; Xinglang Fan; Fangxin Jiang; Fan Liu; Yuan Yin; Hongyi Jin The viscosity of Retard-Hardening Adhesive (RHA) varies with the hardening of resin-based materials and greatly affects the workability and prestress loss of retard-bonded prestressed systems. So far, the effect of aging time...

... test were performed to characterize the dynamic mechanical performance and fatigue property of asphalt materials. The results showed that the co-modified asphalt with 8 % CTR and 3.5 % SBS performed best in a viscosity test at 60°C. At 135°C and 165°C, it exhibited good viscous nature and had...

Experiments were carried out to examine the effect of concentration of nanofluid and temperature on rheological behavior and effective thermal conductivity of non-Newtonian nanofluid. Viscosity and thermal...

A series of tests, including penetration, softening point, ductility and viscosity of different WMA additive concentrations (0...

... bitumen and the storage stability of bitumen modified with montmorillonite (MMT). Four contents (0.2, 0.5, 1, and 3 % by weight) of welan gum were used to mix with base bitumen at a suitable temperature of 160°C. The dynamic shear rheometer was adopted to evaluate the viscosity as the function of shear...
