Research ArticleOpen accessIn the abstractENHANCING ASPHALT RHEOLOGICAL BEHAVIOR AND AGING SUSCEPTIBILITY USING BIO-CHAR AND NANO-CLAYRenaldo C. Walters, Elham H. Fini, Taher Abu-LebdehThe life expectancy of Asphalt Binder (AB) has been negatively impacted by the harsh bombardment of UV rays. UV rays cause asphalt to oxidize faster, which results in deterioration of asphalt rheological characteristics that can lead to pavement distresses. This study investigates the impact of bio-char and nano-clay of asphalt rheological properties. Two nano scale materials were used for this … …American Journal of Engineering and Applied Sciences, Vol. 7, Issue 1 · 24 Mar 2014 · 10,525 accessesView PDFCite
Research ArticleOpen accessIn the abstractEFFECT OF USING STEEL SLAG AGGREGATE ON MECHANICAL PROPERTIES OF CONCRETESultan A. Tarawneh, Emhaidy S. Gharaibeh, Falah M. SarairehThis study presents an evaluation of the physical and mechanical properties and characteristics of steel slag aggregate concrete in comparison with the typical crushed limestone stone aggregate concrete. Hardened concrete consist of more than 70% aggregate due to the high demand in building construction and the increase of the amount of disposed waste material, suppliers and researchers are exploring the … …American Journal of Applied Sciences, Vol. 11, Issue 5 · 10 Feb 2014 · 8,055 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnvironmental Radioactive Impact Associated to Uranium ProductionFernando P. CarvalhoProblem statement: One century of uranium mining in Europe and North-America created a legacy of ore mining and milling sites needing rehabilitation for environmental and human safety. In the last decades developments of uranium mining displaced the core of this activity to Australia, Canada and African countries. In the coming years, uranium mining is expected to grow further, in those … …American Journal of Environmental Sciences, Vol. 7, Issue 6 · 14 Jan 2012 · 8,249 accessesView PDFCite
Research ArticleOpen accessIn the abstractAdsorption of Methylene Blue from Aqueous Solution onto a Low-Cost Natural Jordanian TripoliAtef S. ALzaydienProblem statement: It is well documented that lead is one of contaminants of industrial wastewaters and its pollution exists in the wastewater of many industries. As a result, recent research has focused on the development of cost effective alternatives using various natural sources and industrial wastes. In this setting, the use of low-cost agricultural materials, waste and residues for recovering … …American Journal of Applied Sciences, Vol. 6, Issue 6 · 30 Jun 2009 · 7,945 accessesView PDFCite
Research ArticleOpen accessIn the abstractWastewater Treatment Using Horizontal Subsurface Flow Constructed WetlandS. Sarafraz, Thamer Ahamad Mohammad, Megat J. Megat M. Noor, A. LiaghatThe last few decades witnessed sharp focus on environment pollution and its impact on life in nature. Wetlands can be used for biological treatment of wastewater. Problem statement: Scarcity of water is considered as a global problem and Iran is one the countries which is facing water shortage problem. Pollution of water bodies restrict the availability of water for various … …American Journal of Environmental Sciences, Vol. 5, Issue 1 · 28 Feb 2009 · 8,788 accessesView PDFCite
