There have been several attempts at creating such integrating them within Pavement management systems. paper utilizes replicable deep learning techniques carry out hotspot analyses on urban networks highlighting important pavement...

The increasingly widespread use of smartphones as real cameras on drones has allowed an ever-greater development several algorithms to improve the image’s refinement. Although latest generations drone let user achieve high resolution images, large number pixels be processed and acquisitions from multiple lengths for stereo-view often fail guarantee satisfactory results. In particular, flight altitudes strongly impact accuracy, result in images which are undefined or blurry. This is not...

Road pavements need adequate maintenance to ensure that their conditions are kept in a good state throughout lifespans. For this be possible, authorities efficient and effective databases place, which have up date relevant road condition information. However, obtaining information can very difficult costly for smart city applications, it is vital. Currently, many make decisions by assuming conditions, leads poor plans strategies. This study explores pathway obtain key on roadway utilizing...

The bituminous sub-ballast layer within the ballasted rail track allows some mechanical and environmental advantages. An analytical model of a with has been proposed by considering as viscous-elastic continuous beam discretely supported, at four levels elasticity.The was used to compare performance both without layer. results confirmed that reduces dynamic forces on ground achieves technical objectives reduction borne vibrations increase design life track.

The transition of the road engineering industry to a circular way doing business requires more efficient and sustainable resources, energy, waste management. rates in which reclaimed asphalt is being recycled or reused mixture production process constitutes crucial parameter this transition. This paper aims at establishing further step towards combined circularity sustainability pavements, by introducing framework for quantifying their Material Circularity Index. based on methodology...

The pavement engineering industry, having realized the significance of impacts that it imposes on environment through production, construction and management its products assets, has been driven towards a more sustainable circular way operating. This partly asphalt recycling, which is an area many road authorities have prioritized. However, not all National Road Authorities (NRAs) and/or sector stakeholders seem to be adequately familiar with Circular Economy (CE) concept. paper attempts...

Although asphalt pavements modified with recycled plastic have demonstrated enhanced performance, their recyclability remains under-explored, which is crucial under the scope of a circular economy. To address this, present study investigates multi-recyclability mixtures, both and without modifier, at recycling rate 50 % over two cycles using an open-loop closed-loop model. The research utilised innovative modifier made from hard waste plastics, incorporated into mixture via dry method....

The aim of this paper is to propose a fractional viscoelastic and viscoplastic model asphalt mixtures using experimental data several tests such as creep recovery performed at different temperatures stress levels. From best fitting procedure it shown that both the one curve follow power law model. It suitable for dashpot element arranged in series. proposed also available outside linear domain but case parameters depend on level.

Road pavement conditions have significant impacts on safety, travel times, costs, and environmental effects. It is the responsibility of road agencies to ensure these are kept in an acceptable state. To this end, tasked with implementing management systems (PMSs) which effectively allocate resources towards maintenance rehabilitation. These systems, however, require accurate data. Currently, most rely manual distress surveys as a result, there research into quick low-cost identification...

Although the benefits of asphalt recycling have been scientifically proven and several best practices are being implemented, further research is required in specific specialized areas. One these circumstances Reclaimed Asphalt Pavements (RAPs) that contain modifiers such as elastomers and/or plastomers. Following principles circular economy considering sustainability implications mixtures, this paper deals with multi-recyclability mixtures containing 50% RAP without a recycled plastic...

Reducing ground borne vibrations in urban areas is a very challenging task railway transportation. Many mitigation measures can be considered and applied; among these open trenches are effective. This paper deals with the study of effect, terms reduction vertical horizontal displacements velocities, trenches. 2D FEM simulations have been performed several trench configurations analysed varying main geometric features such as width depth, distance from rail, thickness soil layer over rigid...

The demolition of buildings, apart from being energy intensive and disruptive, inevitably produces construction waste (C&Dw). Unfortunately, even today, the majority this ends up underexploited not considered as valuable resources to be re-circulated into a closed/open loop process under umbrella circular economy (CE). Considering amount virgin aggregates needed in civil engineering applications, C&Dw can act sustainable catalyst towards preservation natural shift CE. This study...

Resource depletion and climate change, amongst others, are increasingly worrying environmental challenges for which the road engineering sector is a major contributor. Globally, viable solutions that comply with principles of circular economy (CE) being investigated can replace conventional asphalt mixtures in post-fossil fuel society. The use reclaimed (RA) widely used well-established method to reduce economic impacts while increasing their circularity. However, RA’s market supply demand...

Abstract. Building Information Modelling (BIM) has emerged as a focal point in the construction industry, garnering substantial attention due to its capacity elevate product quality, facilitate accurate quantity determination, and enhance scheduling efficiency. The inherent complexity of projects necessitates integration BIM models endowed with automation functionalities for schedules cost estimation. This ensures that updates seamlessly occur throughout process, thereby mitigating project...

Asphalt binder is a crucial component of asphalt pavements that undergoes ageing over time, which can result in the reduced performance and deterioration pavements. Consequently, artificial methods play significant role providing valuable insights into behaviour long-term binders. However, consensus on most effective method for simulating remains elusive, leading to disparities outcomes across different research studies. To address this issue, study utilises two thermo-oxidative approaches,...
