Article
Full-text available
Cold bitumen emulsion mixtures (CBEMs) are made up of the same materials that are used in hot mixes. However, asphalt emulsion and water are used in such mixes. To date, many countries are still not using these mixes as a structure layer. This can be attributed mainly to their low resistance to rainfall, long curing time and low early strength. The...

The existence of soluble salts in granular materials of highway pavements has become a widely spread problem in Iraq. This research is performed to evaluate the influence of soluble salts on the engineering properties of a soil-aggregate material brought out from a road fill of a newly constructed rural road in Samawah city, south of Iraq. Soluble...
Article
Full-text available
A previous study conducted by the authors proved that the inferiority of the mechanical properties of Cold Bituminous Emulsion Mixtures (CBEMs) could be overcome by incorporating a waste or by-product material, namely Paper Sludge Ash (PSA). The new CBEMs have demonstrated comparative mechanical and durability properties compared to conventional Ho...
Article
Road pavements are pivotal to the infrastructure, transportation and ultimate efficiency of both the public and the economy. However, they are undeniably having detrimental effects on an already compromised environment. Consequently, a re-think about road pavement construction materials is of paramount importance. Cold mix asphalt (CMA) is a low ca...
Article
Full-text available
Emulsion-based mixtures (EBM) attract less interest to use as a structural layer due to the weak mechanical performance, although it has environmental, economic, energy-saving benefits. Ground granulated blast-furnace slag (GGBS) activated by waste alkaline Ca(OH) 2 solution is used in the present investigation to replace the conventional limestone...
Article
Full-text available
Increasing attention has been paid to use polymer as a modifier in bituminous mixtures manufacturing. Unmodified bituminous mixtures are highly affected by the undesirable environmental conditions at which such mixtures present brittle behaviour and crack at cold weather, whereas present soft behaviour at elevated temperatures resulting in rutting...
Article
Full-text available
High loading rates may produce in structural frames due to some actions, such as explosions or debris impact. The response of structural members to such abnormal loadings should be investigated to provide comprehensive knowledge of their capability to resist impulsive forces. Beam-column joint is considered one of the most important structural comp...
Article
The reduction of both environmental problems and construction costs has motivated the asphalt pavement industry to increasingly use waste materials as alternative raw materials in road pavements construction. This investigation aims to explore the potential of waste calcium carbide residue (CCR) for use as a filler in hot mix asphalt (HMA), by subs...
Article
Full-text available
The tensile strength of asphalt mixtures is one of the main parameters of deterioration and failure in flexible pavements. Hence, in this study, the effects of reinforcing asphalt mixtures, using polypropylene fibers, on their engineering performance were experimentally investigated. A set of cylindrical specimens of asphalt mixtures was prepared a...
Article
Cold asphalt emulsion mixtures (CAEMs) can be said to produce a reduced environmental impact and lower energy consumption in comparison to hot mix asphalt (HMA). They are also safer to use as there is no heating involved in the production and application of such mixtures. However, CAEMs are described as inferior to traditional HMA because of weak e...
Conference Paper
Full-text available
Cold asphalt emulsion mixture (CAEM) has numerous environmental, economic, energy-saving benefits in addition to their advantages for safety, in comparison to the traditional bituminous mixes used in roads. However, CAEM attracts less interest to use as a structural layer due to the weak mechanical performance. The present investigation aims to use...
Article
Full-text available
Abstract: A parametric study is presented in this paper based on validated finite element models that were built in the companion paper that investigates the behaviour of two types of beam-column connections named flush plate connection (FPC) and partial depth end-plate connection (PDEPC) under quasi-static and lateral impact loadings. In the curre...
Article
An extended study on the lateral impact response of end-plate beam-column connections is presented in this paper. A parametric study is presented based on validated finite element models that were built in the companion paper that investigates the behaviour of two types of connections named flush plate connection (FPC) and partial depth end-plate c...
Article
A reliable viscoplastic model of natural and synthetic fibres reinforced cold bitumen emulsion mixture is developed and applied to characterize the rutting behaviour of asphalt pavement by using finite element analysis. It is indicated that the traffic load parameters such as temperature, static loading condition and vehicular speed not only affect...
Article
Full-text available
This research aims to examine the impact of using natural and synthetic fibres as reinforcing materials, on the mechanical properties and water susceptibility of cold mix asphalt (CMA) including indirect tensile stiffness and resistance to rutting, cracking and moisture damage. Four different types of fibres were used: glass as a synthetic fibre, a...
Article
This paper describes the development of a three-dimensional (3-D), finite element model (FEM) of flexible pavements made with cold mix asphalt (CMA), which has itself been reinforced with two different natural fibres: jute and coir. A 3-D finite element model was employed to predict the viscoelastic response of flexible CMA pavements when subjected...
Conference Paper
Full-text available
The enhancement of the performance of flexible pavements by reinforcing asphalt mixtures is considered valuable because of the negative environmental conditions and heavy loads pavements endure resulting in the unsatisfactory performance of conventional mixtures. This research investigates the mechanical properties of cold mix asphalt (CMA) mixture...
Article
Full-text available
A three-dimensional (3D) finite element (FE) model of a reinforced cold bituminous emulsion mixture (CBEM) was built in order to investigate the effect of static wheel load on rutting formation and flexible pavement response. This model was developed to represent a four-layer pavement structure with elastic responses and to simulate the mechanical...
Conference Paper
Full-text available
Abstract: In this research the linear elastic behavior of asphalt mixtures was investigated by using finite element analysis, which pavement construction engineers have tried to adapt for pavement analysis. A three-dimensional (3D) finite element (FE) model of a novel developed fast-curing cold asphalt concrete binder course (CACB) mixture has been...
Conference Paper
Abstract: Overlaying rigid pavements by a thin layer of AC mix is the most employed solution for strengthening the old structure to improve the riding quality. But reflective cracks will prematurely cause poor riding quality, reduce overlay service life and require premature maintenance. The objective of this research is to Second MESAT Conference...
