التكدس المرورى جلطة فى شرايين المحافظات

2017 | الكلمات المفتاحية محافظة سوهاج, التكدس المرورى,
التكدس المرورى جلطة فى شرايين المحافظات
تعد المشكلة المرورية من أهم المشاكل التى تؤرق محافظة سوهاج وذلك على الرغم من أن ملكية المركبات فى محافظة سوهاج منخفضة مقارنة مع العديد من المحافظات الأخرى حيث تقدر ملكية العربة فى المحافظة بحوالى 42 مركبة لكل ألف ساكن مقارنة بمتوسط ملكية المركبات علي مستوي الجمهورية والذي يبلغ 80 مركبه /1000 نسمة على مستوى جمهورية مصر العربية طبقا لما جاء ... إقراء المزيد

MEASURING CONTROL DELAY AT SIGNALIZED INTERSECTIONS: CASE STUDY FROM SOHAG, EGYPT

2016 | الكلمات المفتاحية Signalized Intersections, Control Delay, GPS, Speed Profiles, Stopped Delay, Acceleration and Deceleration,
MEASURING CONTROL DELAY AT SIGNALIZED INTERSECTIONS: CASE STUDY FROM SOHAG, EGYPT
Control Delay is considered the most important measure of effectiveness (MOE) at signalized intersections because it is used in the estimation of level-of-service (LOS) and intersection design. Thus, this paper presents a methodology to analyze and estimate the delay times at signalized intersections in Egypt, using the Global Positioning System (GPS) devices. GPS was used to identify critical points along ... إقراء المزيد

INVESTIGATING THE EFFECTS OF CEMENT AND CEMENT KILN DUST AS A FILLER ON THE MECHANICAL PROPERTIES OF COLD BITUMINOUS EMULSION MIXTURES

2016 | الكلمات المفتاحية cold bituminous emulsion, cement kiln dust, SEM, , ITSM, fatigue, resistance to rutting,
INVESTIGATING THE EFFECTS OF CEMENT AND CEMENT KILN DUST AS A FILLER ON THE MECHANICAL PROPERTIES OF COLD BITUMINOUS EMULSION MIXTURES
The application of cold mixes is lagging behind in the research field, which is quite obvious in a developing country. Furthermore, cold mixes have more economic and environmental advantages than hot mixes. This is the principal motivation for the present research, which aims to improve the mechanical properties of cold mix asphalt. Ordinary Portland cement (OPC) and cement kiln dust ... إقراء المزيد

Application of Cement Dust and OPC as Mineral binder Hot Mix Asphalt Filler in the

2016 | الكلمات المفتاحية Hot mix asphalt, Marshall, Cement dust, BISAR, Pavement responses,
Application of Cement Dust and OPC as Mineral binder Hot Mix Asphalt Filler in the
Many of the asphalt pavement structures in Egypt are exposed to granular disintegration due to a lack of filler properties, which has a negative effect on both the economy and road safety. This paper investigates and evaluates the application of cement dust waste produced from the cement industry and Ordinary Portland Cement (OPC) as a filler material in hot mix ... إقراء المزيد

Toward an operating speed profile model for rural two-lane roads in Egypt

Toward an operating speed profile model for rural two-lane roads in Egypt
The geometric design, especially the horizontal and vertical alignments, of rural two-lane highway facilities is considered one of the most important factors affecting the quality of traffic service and safety. A consistent highway geometric design is defined to be one that conforms to the driver's expectations. In order to calculate the main measures of design consistency, an accurate operating speed ... إقراء المزيد

Creep Stiffness and Permanent Deformation of Rubberized Asphalt

2015 | الكلمات المفتاحية Asphalt Concrete Mixtures, Crumb rubber, Permanent Deformation, Creep Stiffness,
Creep Stiffness and Permanent Deformation of Rubberized Asphalt
The main objective of this research is to determine the effect of crumb rubber on the creep stiffness and permanent deformation of asphalt concrete mixtures. Rubber was used as an additive to the base bitumen (by weight of bitumen in total mix) at four contents: (0, 7, 10, and 13%) by volume of binder. Then, they were exposed to creep ... إقراء المزيد

EVALUATION OF PAVEMENT DISTRESSES APPEARANCE AND PROPAGATION FOR URBAN ROADS IN UPPER EGYPT

EVALUATION OF PAVEMENT DISTRESSES APPEARANCE AND PROPAGATION FOR URBAN ROADS IN UPPER EGYPT
Monitoring and evaluating pavements condition have a multi benefits that can be employed in maximizing network performance. It is used to evaluate the applied maintenance strategies, generating prediction models that describe performance trend in the future, and determining the trigger threshold values for maintenance and rehabilitation (M, R) actions. Also, it can be used for evaluating the quality of paving ... إقراء المزيد

Utilization of Waste Iron Slag on Hot Mix Asphalt Concrete Mixtures

2015 | الكلمات المفتاحية Marshall/Stiffness, Asphalt Concrete Mixtures, Blast Furnace Iron Slag, Indirect Tensile Strength, Compressive strength,
Utilization of Waste Iron Slag on Hot Mix Asphalt Concrete Mixtures
The effect of using waste iron slag on the mechanical properties of hot mix asphalt concrete mixtures was intensively investigated within this research. Waste iron slag that is produced in steel factories as a byproduct was added to the asphalt mixture as a part of the fine aggregate. The studied mechanical properties include Marshall/stiffness, indirect tensile strength and unconfined compressive ... إقراء المزيد

Creep Compliance Characteristics of Cement Dust Asphalt Concrete Mixtures

2014 | الكلمات المفتاحية Cement dust, Asphalt Concrete Mixtures, Creep Compliance, Marshall stability, Indirect Tensile Strength, Compressive strength,
Creep Compliance Characteristics of Cement Dust Asphalt Concrete Mixtures
The current research is directed towards studying the creep compliance characteristics of asphalt concrete mixtures modified with cement dust. This study can aid in assessing the permanent deformation potential of asphalt concrete mixtures. Cement dust was added to the mixture as mineral filler and compared with regular lime stone filler. A power law model was used to characterize the creep ... إقراء المزيد

Effect of Horizontal Alignment Characteristics on Capacity Loss at Rural Two-Lane Roads

2012 | الكلمات المفتاحية capacity at curves, capacity at tangents, horizontal alignment, regression analys, correlation, traffic stream, capacity loss,
Effect of Horizontal Alignment Characteristics on Capacity Loss at Rural Two-Lane Roads
The primary objective of this paper is to explore the impact of horizontal alignment characteristics on capacity and capacity loss at two successive elements, tangent and succeeding horizontal curve. The horizontal alignment chara cteristics include lane width, shoulder width, carriageway width, forward visibility, number of side access points, curve radius, curve length, tangent length, deflection angle and superelevation. Traffic volumes, ... إقراء المزيد
