Research ArticleOpen accessIn the keywordsAssessing and Improving the Performance of Grouted MacadamMomtaz M. Othman, Ahmed Ebrahim Abu El-Maaty, Zeinab S. HusseinThere are many road defects appear in flexible pavement layers. Rutting, raveling and cracks are considered the main problems in Egypt. Using grouted macadam system as a surface asphaltic layer (or called Semi-Flexible Pavement (SFP)) has many advantages such as saving the natural asphalt and enhancing the performance against deteriorations. The main scope of this research is to evaluate and … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 2 · 29 Apr 2020 · 7,078 accessesView PDFCite
Research ArticleOpen accessIn the keywordsIdentification, Characterization and Quantification of Elastomeric/Plastomeric Waste for Sustainable Waste MinimizationKajal Yadav, Sangita, A. ChandraThe present study focuses on the importance of characterization of waste/post consumer polymers. In recent years sophisticated instrumental techniques played an important role in identification and characterization of polymers. Advances in computer techniques have been combined with analytical instruments to give analytical speed, resolution and minimal sample requirements unimagined a few years ago. The present study deals with the development … …American Journal of Environmental Sciences, Vol. 1, Issue 3 · 30 Sep 2005 · 7,056 accessesView PDFCite
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 PDFCite
Research ArticleOpen accessIn the abstractThe Effects of Using Crumb Rubber Modified Binder in an Asphalt PavementSayed Mohamad Soleimani, Alanoud Faheiman, Zainab MowazeIn this study, laboratory investigations have been carried out to characterize and demonstrate the improved performance of asphalt after modifying it with crumb rubber. The study has been divided into two main parts. Firstly, the physical characterizations of crumb rubber modified bitumen with different percentages of crumb rubber have been evaluated using penetration, softening point, viscosity, ductility and thin film … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 2 · 14 May 2020 · 8,377 accessesView PDFCite
Research ArticleOpen accessIn the abstractCharacterization of Recycled Asphalt Pavement (RAP) for Use in Flexible PavementAhmed Ebrahim Abu El-Maaty, Abdulla Ibrahim ElmohrDue to economical reasons and the need for environmental conservatism, there has been an increasing shift towards the use of Recycled Asphalt Pavement (RAP) materials in the pavement construction industry. The majority of HMA mixtures in Egypt are produced only from virgin materials although there are about 4 million tons per year of reclaimed asphalt materials, due to continuous pavement … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 2 · 20 Jun 2015 · 9,213 accessesView PDFCite
EditorialOpen accessIn the abstractRECENT TRENDS AND CHALLENGES OF ENERGY EFFICIENT AND SUSTAINABLE BUILDINGSChiara BedonAccording to several studies (e.g., the Intergovernmental Panel on Climate Change (IPCC, 2014), the US Energy Information Administration (US EIA, 2014), warming of the climate system is unequivocal and mainly derives from greenhouse gas emissions due to human activities. Global Carbon Dioxide (CO2) emissions from fossil fuels, for example, are estimated to be 29% higher in 2035 than they were … …American Journal of Engineering and Applied Sciences, Vol. 7, Issue 3 · 11 Sep 2014 · 8,497 accessesView PDFCite
Research ArticleOpen accessIn the abstractApplication of Trujillo Algorithm for Analyzing of StructuresH. Hashamdar, Z. IbrahimProblem statement: The Trujillo algorithm is indirect method and has been used in this study. The approach is based upon the principle of conservation of energy. Approach: Cable structures are very light and flexible and they undergo appreciable deflections when subjected to external loading. Results: Since all the main load-carrying members in cable structures are usually in tension, there are … …American Journal of Applied Sciences, Vol. 7, Issue 3 · 31 Mar 2010 · 7,846 accessesView PDFCite
Research ArticleOpen accessIn the abstractBase Course Modification through Stabilization using Cement and BitumenS. M. Marandi, P. SafapourThe main objectives of this research was to analyze the use of combined cement and bitumen emulsion in base course stabilization in details and examine its replacement with conventional pavement in regions with low quality materials and limited construction period. To conduct the objectives, the research divided into three phases. Phase I involved the optimization of cement and bitumen emulsion. … …American Journal of Applied Sciences, Vol. 6, Issue 1 · 31 Jan 2009 · 7,802 accessesView PDFCite
