In the current paper, a comprehensive database comprising a total of 83 simply supported deep beams, strengthened using FRP reinforcement, was carefully collected from the literature. The collected data served as the foundation for an investigation into the Strut-and-Tie modelling (STM) provisions presented within three international codes, namely...
In this study, a 2D finite element analysis was performed utilising the ABAQUS/Explicit method to present a model capable of estimating the response of GFRP RC continuous deep beams. Four GFRP-reinforced specimens were experimentally tested and then employed to validate the proposed FE model. Two different section depths (300 and 600 mm) and two we...
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...
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...
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...
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...
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...
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...
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...
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...
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...
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...
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...
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...
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...
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...
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...
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...
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...
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...
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...
