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
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

Creep Compliance Characteristics of Cement Dust Asphalt Concrete Mixtures

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

Effect of Highway Geometric Characteristics on Capacity Loss

2012 | الكلمات المفتاحية highway transportation, capacity, highway geometry, Horizontal curve, flow-density relationship, Regression analysis,
Effect of Highway Geometric Characteristics on Capacity Loss
The estimation of roadway capacity is essential in the planning, designing, and operation of highway facilities. This paper aims at assessing the influence of highway geometric characteristics on capacity at tangents and horizontal curves as well as on capacity loss at the change from tangent to curve. Traffic and geometry data obtained from twelve rural, two-lane road sites in Minoufiya ... إقراء المزيد

Assessment of Performance Measures for Rural Two-Lane Roads in Egypt

2011 | الكلمات المفتاحية Two-lane highways, Performance measures, Platooning variables, Traffic flow, Follower density,
Assessment of Performance Measures for Rural Two-Lane Roads in Egypt
Two-lane, two-way roads represent a particular challenge to traffic engineers as they constitute the majority of any network, e.g. about 75% in Egypt. Measuring traffic performance at these facilities is a complex issue due to their unique characteristics. In this paper, seven performance measures and three platooning variables were defined and calculated for each direction of travel at eight study ... إقراء المزيد

Quantifying the Impact of Highway Geometry on Traffic Performance for Two-Lane Roads
This paper aims to quantify the impact of highway geometry characteristics of rural two-lane, two-way roads on traffic performance. To achieve this aim, twelve sites were selected from Minoufiya Governorate, Egypt. Each site is consisted of two elements, horizontal curve and tangent, with various geometric characteristics. Traffic surveys were carried out using automatic traffic counters to collect sufficient traffic data ... إقراء المزيد

2011 | الكلمات المفتاحية Two-lane highways, Performance measures, Platooning variables, Traffic flow, Follower density,
Evaluation of performance measures for rural two-lane roads in Egypt
This paper presents an empirical evaluation of the relationship between operational performance and platooning phenomenon in rural two-lane roads in Egypt. Seven performance measures and three platooning variables were defined and calculated for eight study sites using traffic data from roads in Minoufiya governorate, Egypt. Using graphical and statistical analyses, the associations between the performance measures and the platooning variables ... إقراء المزيد

3D FINITE ELEMENT ANALYSIS OF RIGID AIRPORT PAVEMENT-PARAMETRIC STUDY

2007 | الكلمات المفتاحية 3D Finite Element,
3D FINITE ELEMENT ANALYSIS OF RIGID AIRPORT PAVEMENT-PARAMETRIC STUDY
A parametric three-dimensional finite element study has been carried out to investigate the effects of different parameters on the deflections and bending stresses in the jointed rigid airport pavement system. These parameters are modulus of elasticity of subgrade, slab thickness, thickness of subbase, dowel bars spacing, and dowel bars diameter. Two cases of loads are considered, namely interior loads, and ... إقراء المزيد
