Research ArticleOpen accessPhrase in the titleNew Approach in Application of the AHP–Fuzzy TOPSIS Method in Mineral Potential Mapping of the Natural Bitumen (Gilsonite): A Case Study from the Gilan-e-Gharb Block, the Kermanshah, West of IranElham Rahimi, Younes Shekarian, Salman Mastri Farahani et al.The Gilan-e-Gharb block is known as a prospective area for hydrocarbon resources in the form of oil, gas in deep potential and natural bitumen (Gilsonite) on the surface. Natural bitumen is not clearly detectable by geochemical or geophysical methods. Hereupon, identifying high potential areas for further exploration, attempted with the help of AHP-Fuzzy and TOPSIS methods. The comprehensive database of … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 1 · 2 Mar 2020 · 7,980 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsGilsonite Modified Asphalt for Use in Pavement ConstructionAliasghar Akbari Nasrekani, Mostafa Nakhaei, Koorosh Naderi et al.Properties such as durability and moisture resistance of asphalt concrete significantly improve pavement service life. When siliceous aggregate is used, then preventing moisture damage and stripping become distinctly required. Typically, stripping could be prevented by either using antistripping agents or by modifying the binders. The anti-stripping agent achieve its purpose by changing the aggregates' affinity for water through changing the … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 2 · 3 Apr 2018 · 9,380 accessesView PDF Cite

Research ArticleOpen accessIn the abstractInfluence of Bitumen Addition on Sabkha Soil Shear Strength Characteristics under Dry and Soaked ConditionsFahad A. Alotaibi, Humoud Melfi AldaihaniHigh salt content in sabkha soils means they are significantly affected by changes in water content. Dissolution of salts within sabkha soil mass decreases their shear strength upon inundation with water, resulting from the destruction of cementation bonds between soil particles. Therefore, successful improvement for these soils must be based on reducing the dissolution of sabkha salts to minimize their … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 4 · 13 Nov 2018 · 7,388 accessesView PDF Cite
