Research ArticleOpen accessIn the abstractDEVELOPMENT OF TEST PROTOCOLS FOR THE ANALYSIS OF MAGNETO-RHEOLOGICAL PROPERTIES OF FIELD-RESPONSIVE BITUMINOUS BINDERSEzio Santagata, Orazio Baglieri, Lucia Tsantilis, Arianna VercelliMagneto-rheological fluids are materials that exhibit a significant change in their rheological properties in the presence of a magnetic field. Because of such a field-dependent behavior, they can act as smart materials in applications in which changeable performances are desired. In road pavement engineering, the use of bitumen-based magneto-rheological fluids may open innovative scenarios related to the construction of smart … …American Journal of Applied Sciences, Vol. 11, Issue 3 · 20 Jan 2014 · 6,654 accessesView PDFCite
Research ArticleOpen accessIn the abstractImaging Spectroscopy and Light Detection and Ranging Data Fusion for Urban Features ExtractionMohammed Idrees, Helmi Zulhaidi Mohd Shafri, Vahideh SaeidiThis study presents our findings on the fusion of Imaging Spectroscopy (IS) and LiDAR data for urban feature extraction. We carried out necessary preprocessing of the hyperspectral image. Minimum Noise Fraction (MNF) transforms was used for ordering hyperspectral bands according to their noise. Thereafter, we employed Optimum Index Factor (OIF) to statistically select the three most appropriate bands combination from … …American Journal of Applied Sciences, Vol. 10, Issue 12 · 28 Oct 2013 · 7,152 accessesView PDFCite
Research ArticleOpen accessIn the abstractUtilization of Recycled and Waste Materials in Various Construction ApplicationsJohnny Bolden, Taher Abu-Lebdeh, Ellie FiniMore production equals more waste, more waste creates environmental concerns of toxic threat. An economical viable solution to this problem should include utilization of waste materials for new products which in turn minimize the heavy burden on the nation’s landfills. Recycling of waste construction materials saves natural resources, saves energy, reduces solid waste, reduces air and water pollutants and reduces … …American Journal of Environmental Sciences, Vol. 9, Issue 1 · 15 Jan 2013 · 24,562 accessesView PDFCite
Research ArticleOpen accessIn the abstractStructure of Lamellae and Chloride Cell in the Gill of Alosa Caspio Caspio (Clupeidae, Teleostei)Z. Saadatfar, D. ShahsavaniAs a surface for respiratory gas diffusion, ion regulation and waste excretion, gill epithelium of Alosa Caspio Caspio has been investigated. Problem statement: Surely, morphological study of gill cells is the main route for giving the basic data which can be inductive for physiological and pathological investigations. Approach: Gills were removed from Alosa Caspio which is from euryhaline species and … …American Journal of Applied Sciences, Vol. 8, Issue 6 · 13 Jun 2011 · 6,881 accessesView PDFCite
Research ArticleOpen accessIn the abstractBonding Property of Bituminous Crack Sealants in the Presence of WaterEllie Fini, Taher Abu-LebdehProblem statement: Crack sealing and filling is the most widely used maintenance activity for in-service pavements. If an appropriate sealant material is selected and properly installed at the appropriate time of the pavement life, it retards pavement deterioration and increases its service life at a relatively low cost. However, in some cases it is reported that sealants failed prematurely, mainly … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 1 · 12 Mar 2011 · 8,338 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
Research ArticleOpen accessIn the abstractDetermination of Rheological Properties of Bio Mastic AsphaltR. Muniandy, H. Jafariahangari, R. Yunus, S. HassimDue to the high oil prices the price of asphalt binder has increased tremendously. This scenario has warranted demand for higher viscosity cheaper asphalt for pavement construction. A study was conducted to take advantage of the Empty Fruit Bunch (EFB) of Date and Oil Palm trees (which are considered as waste) to produce cellulose fiber to be used as additives … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 3 · 30 Sep 2008 · 8,067 accessesView PDFCite
Research ArticleOpen accessIn the abstractThickness Analysis of Stone Mastic Asphalt (SMA) Slab Compacted Using a Newly Developed Roller CompactorR. Muniandy, F.M. Jakarni, S. Hassim, A.R. MahmudPavement mix design procedures and specifications are usually derived from laboratory experiments. Therefore, laboratory experiments should be able to simulate to a high degree the conditions in the field, especially in term of compaction procedures. Based on literature reviews and analysis of past studies, it can be concluded that there are no exact method for laboratory compaction that can simulate … …American Journal of Applied Sciences, Vol. 4, Issue 4 · 30 Apr 2007 · 7,476 accessesView PDFCite
Research ArticleOpen accessIn the abstractFunctional Planning Criterion of Forest Road Network Systems According to Recent Forestry Development and Suggestion in TurkeyMurat Demir, Mesut HasdemirEnvironment of the conscious of puclic opinion is increase recent years. When making use of the forest ecosystem for various purposes, care must be taken not to spoil the forest structure. To achieve this, forests must be used according to forestry techniques. Forest roads planning standarts (slope, width, pavement, drainage etc.) are different in production forests, forestation, national park and … …American Journal of Environmental Sciences, Vol. 1, Issue 1 · 31 Mar 2005 · 7,280 accessesView PDFCite
Research ArticleOpen accessIn the abstractApplication of Bio-Modified Montmorillonite Clay to Enhance Asphalt Oxidation ResistanceShahrzad Hosseinnezhad, Elham H. Fini, Taher M. Abu-LebdehThis study evaluates the effectiveness of using a Bio-modified Nanoclay additive (BNC) to reduce the oxidative aging of asphalt pavements. The study results through X-Ray Diffraction analysis showed that the modification of montmorillonite clay with bio-modifier increased the basal d-spacing of clay. The resulting nanoclay with increased interlayer spacing was chosen for application in asphalt binder. Rheological characterization of clay-modified … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 2 · 31 Mar 2018 · 9,054 accessesView PDFCite
