الويب2 جمادى الأولى 1445 بعد الهجرة Warm mix asphalt mixtures became attractive paving mixes by reducing the production temperature to around 25–40 °C as compared to that of conventional hot mix asphalt (HMA). This study aims to evaluate the warm mix asphalt (WMA) using wax-based additives by incorporating two types of industrial wastes. The potential application of
الويبAsphalt cement and finer aggregate portions provide the mastic that holds the stone in close contact. Typical mix design will generally have 6.0–7.0% medium-grade asphalt cement (or polymer-modified AC), 8–13% filler, 70% minimum aggregate greater than 2 mm (No 10) sieve, and 0.3–1.5% fibers by weight of
الويبThe proposed radial compartmentalization is validated based on the evaluation of powder mixing within the periodic section. In this study, a variance-based index, relative standard deviation (RSD) (Gao, Yijie et al. 2012), is used to compare the surrogate model based on compartments with the original DEM model and evaluated using Eq.

الويب19 صفر 1444 بعد الهجرة Fluoride ions are toxic, and F− in groundwater for drinking should be sufficiently reduced to be less than the regulated concentration. In this study, cellulose nanofibril-containing iron oxyhydroxide (FeOOH) powders were synthesized, and their F− adsorption behaviors were studied under various conditions. 2,2,6,6-Tetramethylpiperidine
الويب27 ذو الحجة 1423 بعد الهجرة A new process for the synthesis of metallic Ni, and Ni–Co alloy nanoparticles at a relatively low temperature is reported. The process consists of heating a precursor containing a methyl hydrazine complex of the respective metal ions in nitrogen atmosphere at temperature as low as 400. °C.. The metallic Ni and Ni–Co alloy powders
الويبIn the analysis, the solvent tetrahydrofuran (THF) is used to eliminate interference from hydrogen bonding in the carbonyl absorption region for the determination of ketones, carboxylic acids, anhydrides, and 2-quinolone types. THF is a cyclic ether having a strongly electronegative oxygen within the
الويب20 ذو القعدة 1435 بعد الهجرة This study focussed on application of coal waste powder (CWP) in hot mix asphalt. •. The use of CWP had no detrimental effects on stability and stiffness of HMA. •. The moisture resistance indices in CWP mixes was even higher than the reference •. The CWP mix had higher toughness index or flexibility than the reference
الويب1 شعبان 1430 بعد الهجرة Druta et al. used X-ray computed tomography to qualitatively analyze the blending state of virgin bitumen containing metal powder in the simulated asphalt mixture and found that the virgin and RAP
