Modification of asphalt with nanocomposite now it's considered a new approach to improvement of the asphalt characteristics, Chalcogenide d-element it will be used here as an improver to asphalt. The physical and mechanical characteristics of asphalt were examined in this paper, along with comparative rheological testing on binders and mechanical tests for unmodified and modified asphalt with nanocomposite (ZnO/PMMA). In order to increase its performance, a ZnO/PMMA nanocomposite was added to asphalt (60/70) and binders in different amounts (0.2%, 0.4%, 0.6%, 0.8%, and 1%). It was discovered t
Read MoreVarious commercial thermoplastic polymers, including styrene-butadiene rubber (SBR), polyacrylonitrile (K), polystyrene (PS), polypropylene (PP), and polychloroprene (PC), are employed to modify two types of asphalt: asphalt 60/70 Suez (L) and asphalt 80/100 Alex (H). The optimal ratio of polymer additives, introduced using a hot mixing process at temperatures between 150°C and 170°C, was determined based on the measurements of penetration, softening point, penetration temperature susceptibility (PTS), and penetration index (PI) for the cooled blended formulations. For asphalt L, the ideal p

Every resin was utilized as an additive, combined with a high-temperature hardener, to modify two types of locally available asphalt (designated M and N types) with varied constituents. The study assessed the performance of these epoxy resin-asphalt mixtures in enhancing critical properties such as penetration, softening point, penetration temperature susceptibility (PTT), and penetration index (PI). These improvements were analyzed ba
Read MoreSulfadiazine (SDZ) is a pharmaceutical pollutant frequently detected in water, posing significant health and environmental risks. To address this issue, the current research explore the use of a novel adsorbent, date seed-based activated carbon (DSAC), for the effective removal of SDZ. DSAC was optimized using response surface methodology (RSM) under preparation conditions of 2.30 minutes activation time, 490 W radiation power, and an impregnation ratio (IR) of 1.60 g/g, achieving a estimated SDZ removal of 94.30% (experimental: 90.70%; error: 3.90%) with a DSAC yield of 26.22% (experimental:
Read MoreBoth lead (Pb²⁺) and hexavalent chromium (Cr(VI)) are highly toxic pollutants which need to have strategies for their removal. In this work, graphene oxide (GO) and thiourea-functionalized graphene oxide (TU-GO) were prepared and characterized by means of scanning electron microscopy (SEM), FTIR, Raman, UV-Vis, and BET analyses. Compared to GO, TU-GO showed higher surface area and enriched N/S functional groups. For adsorption experiments, an equilibrium was rapidly reached for Pb²⁺ and was slower for Cr(VI) uptake. Isotherm analysis revealed Pb²⁺ adsorption was Langmuir type monolaye
