<span>Using of Reclaimed Asphalt Pavement (RAP) has been become indispensable in most of the world nations as for its many benefits as significant cost savings and provide environmental benefits. Many factors such as virgin materials, binder content, availability of RAP, viscosity of binder and extent of deterioration had important role in effecting on Optimum percentage of RAP. In this study, effect of using RAP on the asphalt mixture properties and the its optimum ratio was determined to achieve the objective of the study. The glass fiber (GS) was used as additives to improve the asphalt mixture. It has been observed from the previous researches that the optimum percentage of reclaimed asphalt use is not determiner and is disagreed from project to project. So, different percentages of RAP was (25%, 50%, 75%, 100%) by weight of aggregate were added as well as using the additive GS at optimum bitumen content. The study is revealed that untreated 100% RAP materials are not good as a bituminous mix. and was showed that mix prepared with 25% RAP gave nearly the same physical and strength parameters as virgin bituminous mix. From results of study, the use of RAP until (%50) as a maximum percentage in unmodified asphalt mixture course sustained good results. To achieve better performance, the percentage of 25% RAP was used with percentage of 0.26% GS. This mix achieved the specification requirements and ensured the degree of better performance for paving. The economical evaluation of using percentage of 25% RAP with percentage of 0.26% GS was also studied. The results indicated that, about 21% of the cost was saved.

<span>Highways play an important role in developing the country. Highways affect directly on the economy, society, culture and security, so the scientists are looking for developing the performance of highways and low maintenance cost. The main objective of this study is to modify the bituminous mixed by utilization of waste industrial materials. , There are many wastes industrial materials can be used in bitumen. A study has been carried out in this search to illustrate the use of fly ash, (byproduct of combustion Pulverized coal in power plants , it produced during combustion of coal in bituminous paving mixes), Silica Fume,( by- product of producing silicon metal or ferro silicon alloys in smelters using arc furnaces) . For comparison, control mixes with modified bituminous mixes has been considered. Marshall Test has been conducted for the purpose of mix design as well as appreciation of paving mixes. It is observed that the mixes with fly ash and silica fume as modifiers modify the properties compared to control mixes. In this paper Silica Fume and Fly Ash are used as a modifier. Marshall stability test was conducted according to( ASTM D 6927-06 ). The percentages of modified mixtures used are 2, 4, 6, 8 and 10 % by bitumen weight. The results showed that the Marshall stability modified with SF and F.A were increased by 18.4% and 22.3 % respectively. So, we can concluded that adding SF and FA to asphalt binder success in improving the properties of bituminous mixes for flexible pavement. Hence, it has been recommended to utilize Silica Fume and Fly Ash wherever available, not only reducing the cost of construction, but also solve the bituminous mixes properties.

<span>This paper presents a numerical study to identify the geometrical dimension ratios of the section that make introducing stiffeners to the cold-formed channel sections, subjected to bending, most effective. A V-shape stiffener was introduced to the web and/or the lipped flanges of such sections. A series of nonlinear finite element models has been carried out to investigate the flexural behaviour of the stiffened beam sections. The study shows that introducing stiffener to the web of channel is more effective than if it is used in the compression flange, in terms of increasing the flexural strength and delaying of local and distortional buckling failure modes. However, such effectiveness is not absolute, but it is highly dependent on the geometric properties of the section such as; flange breadth to web height ratio (bf/hw) and web height to its thickness ratio (hw/t). Indeed, considering this finding would help in economic design of such sections and optimal use of material. Keywords: Cold-formed section; Stiffeners; Finite element analyses; bending.</span>

<span>This study aims at using the sugar by-product (dry vinasse), as one of the concrete production requirements, instead of getting rid of them in vain. Dry vinasse was obtained by drying liquid vinasse at 250 ° C. In this study, dry vinasse is used as a friendly environmental material to improve properties of cement mortar and concrete, through studying its effect on setting time and compressive strength of cement mortar and concrete. Effect of dry vinasse on compressive strength of cement mortar and concrete by using different doses of dry vinasse 0 %, 0.2 %, 0.3 %, 0.4 %, and 0.5 % by weight content of cement is studied. Compressive strength was determined by standard specimens (40x40x160mm) for cement mortar and standard cubes specimens (150X150X150mm) for concrete. By cylinder specimens (150X300mm), the splitting strength was determined and the flexural strength was determined by beam specimens (100X100X500mm). All the specimens were cured in water and tested for 7 and 28days for cement mortar and concrete. The splitting strength and flexural strength were done for 28 days. It is found that, dry vinasse addition causes increase in setting times. With comparing the results of compressive strength of cement mortar and concrete with and without dry vinasse, it is showed that, there are noticeable increases in the results of compressive strength, splitting strength and flexural strength.

<span>This essay seeks to provide a theoretical discussion of the normative and juristic position with respect to building and using minarets in contemporary mosques. It provides arguments dealing with its function and purpose and the way mu'adhen should relate to it in light of current loudspeaker technology. The essay investigates relevant religious scripture and authoritative scholarly textbooks on the subject matter, in attempt to deduce the proper rulings of 'Fiqh' on basic issues pertaining to programming and designing a place for propagating adhan from the mosque. More fitting alternatives are proposed with general theoretical guidelines for architects and urban designers. The author concludes that traditional minarets are no longer needed in contemporary mosques, and that the expenses that they cost should be invested elsewhere. Loudspeaker Towers are far more practical and far less costly. The author also proposes a kiosk outside the mosque for the mu'adhen, since he argues that adhan should not be delivered from inside the mosque. These findings are expected to challenge commonly held beliefs with respect to a minaret, and the author looks forward to rigorous and scholarly discussions on the matter.</span>

We established that any shape for the ‘Salat space’ plan besides the Orthogonal Polygon which takes the complete undivided ‘Musalliah unit’ for a strict module in its composition, would yield juristically unfavorable effects in the way rows of Musalleen are lined up behind the Imam, and would diminish the use that can be made of Waqf money in hosting the largest possible number of ‘Musalleen’ within the bounds of available space.</span>

<span>The term of sustainability goes beyond applying green architecture strategies. Sustainability refers to techniques which conserve resources, preserve the natural environment, protect local population, and support the principle of justice and equity. Therefore, the achievement of sustainability in the field of construction requires great and multi faces effort to solve the social, economic, and environmental problems. At the local level (Egypt), although there are serious steps toward more sustainable construction industry, many research studies confirmed that the already used system currently in Egypt to rate the sustainable buildings (Green Pyramid Rating system, GPRS) needs to be developed in order to be more effective and usable. There is a great need for developing a rating system for sustainable hotels which can classify hotels in Egypt in terms of sustainability in a comprehensive way starting from early design stages and continue to evaluate the building during and after the construction stage. Therefore, it is necessary to benefit from the systems which are used globally for rating sustainable buildings in order to create a local system by modification of the already existed criteria and to add new criteria in order to achieve a system which meets the local requirements. This research paper suggests a sustainability rating system which classifies hotels in the southern region of Upper Egypt based on improving the local system (GPRS) to be used for classifying hotels particularly because hotels are considered from the most energy consuming buildings and they generate a huge amount of wastes in addition to the increasing awareness of users who consider the sustainable and environment friendly hotels as preferred destinations. The suggested rating system which is Green Pyramid Rating System for hotels, (GPRS-H) is based on using the criteria of the German system (Deutsche Gesellschaft für Nachhaltiges Bauen, DGNB( by modifying them to be more suitable for the local environment in Egypt in addition to excluding certain criteria which are not consistent to the local context. Additionally, the principle of participation has been applied here to help in determining logic relative weights for the criteria and indicators of the suggested system through conducting a questionnaire for the experts in the field of sustainable buildings. The suggested rating system includes six categories of criteria. The environmental quality occupies the first rank in terms of relative weight, then the economic quality, social and cultural quality, technical quality, planning and construction quality, and site quality. Each category includes some criteria which can be evaluated by using certain indicators. Keywords: Sustainable hotels, Green Pyramid Rating System (GPRS), German system for rating sustainable hotels (DGNB), Environmental sustainability, Economic sustainability, Social sustainability.</span>

<span>Building sector consumes 40% of the total energy consumption worldwide. This number is much higher in Egypt. It reached 52% of total energy sold in 2014 with an annual average growth of 5.2%. Public buildings energy consumption; in turn; has a great effect on total energy consumption. In Egypt public buildings represent 40% of the Egyptian building sector. They can give a large potential in reducing total national energy demand and solve a part of energy problem in Egypt. Moreover, they can generate energy to be nearly zero energy building or even zero energy building “off grid connection buildings” in an ambitious plan. Using renewable energy techniques (such as; solar cells& wind turbines) is also considered an optimum solution in this field. This paper targets zero energy public building in Egypt. It suggests an intensive design methodology which based on three major phases: first- is to design an energy efficient public building, second- is to reduce the building energy consumption to the minimum, then the third- tends to produce energy and cover the building needs. To check the efficiency of the proposed methodology, an experimental study is applied on an office building model as case study of public building in Egypt. Design Builder simulation program is used to calculate and compare the building energy consumption in the three successive phases. After applying “the intensive methodology for designing zero energy public buildings” on the proposed office building model, energy consumption indicates initial energy reduction and the consumption became 245232.39 kWh/yr. (28kWh/m2.). Once again, at the end of the consequential phases, the installed photovoltaic panels succeeded in producing 107923.2 kWh/year, and an array of 408 microwind turbines added 138964.8 kWh/yr- the sum of the energy produced comparable with the mentioned consumption conclude mathematically zero needs. At the end, the experiment shows that becoming near zero energy building, or zero energy building, or even energy building plus can be practically true in the upcoming near future. Moreover, calculations and comparisons support using the intensive methodology in designing zero energy public building in Egypt.

<span>Thermal insulation is one of the most significant solutions to reduce energy consumption in buildings. Therefore, using insulation materials with low heat transmission became an important issue. Recently, Nano-materials show great progress in the thermal insulation field in the hot desert climate. Several alternatives of Nano-materials in the glass windows were examined in this study. (Two layers from clear glass filled with the nanogel). It was found that it could save 11% of the total annual energy demand for cooling in comparison with the currently used glass in New Aswan buildings (Single glazing 3mm). This improvement percentage is considered twice the value of using double-glazing. This result is due to the low value of heat transmission for the nanogel in comparison with the air and argon. Moreover, the merged Nano-materials with argon and two layers of single glazing save about 26% of total annual energy in comparison with the current situation. Therefore, this study is considered an important attempt towards reducing energy consumption in the residential Building of New Aswan city.

<span>The research aims to study the effect of orientation and different floors on the thermal performance of spaces in university buildings during the hot period of the university year in the building of the Faculties of Agriculture and Education at New Sohag University. To achieve the objective of the study, the research depends on the analytical method and field measurements, which includes field measurements, so (outdoor and indoor temperatures, and relative humidity) ) were measured for the spaces of the Faculties of Agriculture and Education overlooking the yards as well as on the external facades when the different orientations and floors, which represents the measurement of 6 days of each month (March, April, May). The results showed the convergence of indoor temperatures for all directions during the hot period in the building of the Faculties of Agriculture and Education, where we find that the average difference is not more than 2k° because the ventilation is insufficient in the spaces. The indoor temperatures of the spaces overlooking the courtyards of the Faculty of Agriculture and Education on the outdoor were reduced by an average of 1.0 2k° during the hot period. The spaces of the final floor also recorded higher of indoor temperature than the second floor spaces during the hot period in the faculty of agriculture and education building, in order to expose the ceiling of the final floor of direct solar radiation. The indoor temperatures of the spaces with different directives in the Faculties of Agriculture and Education building during the hot period are also shown to be higher than the range of temperatures accepted most of the time after 12:00 pm (which represents 50% to 60%). Of the total number of hours of measurement during the hot period of the academic year. Therefore, it’s recommended that there is continuous ventilation in the educational spaces so that indoor temperatures don’t rise above the range of indoor temperatures acceptable for the comfort of students, which affects their performance and educational achievement. </span>

<span>As a result of publishing the concept of "Globalization" all over the world, The rate of urbanization is vast increasing, so the cities have witnessed an unprecedented civilization acceleration., but this fast life affected the economic, social and cultural life styles of communities, These differentiations are also effective in the formation of urban spaces and architecture and in the generation of urban life quality at cities. Due to "Fast" does not always mean progress and more competitiveness, “Cittaslow " has appeared as sustainable model based on an alternative philosophy of globalization and fast life. It is a global organization that strives to achieve the goal of sustainable urban development through the avoidance of global culture in planning, urban design and infrastructure. Their policies promote local diversity and economic and cultural strengths, build on historic resources and traditions, and encourage a slow, relaxed pace of life. The research was based on the construction of a comprehensive theoretical framework through the review and study of literature on the subject of the concept of "Globalization" and its effects on the urban system and the rate of urbanization and urban problems which are increasing significantly according to the rapid changes that have developed in many cities, Within the scope of this study, ‘Cittaslow’ movement is addressed as a different approach to building sustainable cities to face the effects of the ideas of globalization and fast life on the urban system , by ensuring the notion of ‘Cittaslow’ is clearly understood, urban parameters suggested by "Cittaslow" within the framework of achiving sustainability as a solution to modern-day urban problems. Then the research analyze one of slow cities experiment. In an attempt to devise whether the application of "Cittaslow" policies would be a valuable approach for cities planners to adopt, to aid in addressing issues of small towns in Egypt and to assist them in supporting sustainable urban development includes the overall results of the search and recommendations. The study aims to take advantage of “Cittaslow" policies and principles to turn the theoretical underpinnings of sustainable development and Local Agenda 21 into a more powerful and practical action plan. In an attempt to devise processes within which to activate “Cittaslow” policies and principles to implement local urban sustainable development.</span>

<span>The central district of any Islamic city is the location of the most distinctive architectural and urban features. This district includes the important architectural monuments such as Friday mosques, bazaars, Khans and Madrasas. To analyse the image of the Egyptian city during the Islamic period, it is important to understand how Egyptian Muslims conceptualized and represented their cities and to clarify the forces and underlying causes that underpin the distinguished visual appearance of such cities. It is investigated here how the aspects of the Islamic version of the image of city centres in Egypt can be translated to certain concepts and codes which can be considered in the development of the image of contemporary city in order to regain its identity and achieve the visual sustainability. To achieve this aim, Lynch analysis is applied here to investigate the five components of the image of Islamic Egyptian city centre, and then it is evaluated against certain criteria. This paper aims also to identify the positive and negative aspects of the visual image of Egyptian city during the Islamic era by focusing on the overhead image as a method of city perception at the present. It is concluded here that the visual quality of the Islamic image of Egyptian city centre is affected by some negative aspects such as; shortage of accessibility, absence of legible streets network, closed fields of vision, and similarity and monotony of landmarks. But on the other hand, these aspects which can be interpreted to be negative are justified in terms of the religious, cultural, and social contexts of the Islamic era. The main principles of designing the Islamic city have been derived and clarified as certain concepts such as community-based city design, the balance between visual exposure and privacy, and design for climate. It is confirmed here that, to create a link between the design of the city image during the Islamic era and the contemporary version of the city image, these principles should be applied to the design of contemporary cities using the available new techniques in order to meet the different needs of users and to investigate these principles deeply to go beyond merely using the Islamic styles in buildings facades in order to achieve the resilience of such image to the different changes and challenges.</span>
