The concept of sustainability and resilience has gained significant importance in recent years in the infrastructure engineering industry. Key challenges currently faced by the infrastructure industry worldwide include obsolescence, growing demands, climate change, increased vulnerability, demand for multifunctionality, and growing interdependencies among different asset types. With the recent changes in the economic, social, and environmental scenarios, an increasing pressure exists to develop robust, flexible, and multifunctional asset management solutions that not only suit the needs of the present, but also are safe, secure, and resilient to what the future may hold. Ultimately all infrastructure assets interact with the ground, and their integrity relies substantially on the performance of geotechnical assets, thus making geotechnical asset management a critical starting point in future proofing the infrastructure network. The paper highlights the need to devise resilient asset management solutions. The paper focuses on two transport modes, namely highways and railways, and aims to present an asset management framework that will test the resiliency of current geotechnical solutions to the plausible conditions of the future. The proposed asset management framework will enable strategic decision makers to evaluate the resilience potential of proposed geotechnical asset management solutions in light of future conditions with varying socioeconomic and environmental patterns. © 2014 American Society of Civil Engineers.

This paper explains a concrete repair project at Midland Links Motorway bridges in West Midlands UK in which a novel modification technique was adopted and discusses the applicability of same approach to other highway structures around the world. The modification to the traditional supporting steelwork system (SSS) required for carrying out concrete repairs to a deteriorated non-standard structure is made. The non-standard structure of Midland Links under study was a viaduct passing over a river (i.e. waterway). Traditional SSS was not possible to use because the trestle arrangement could not be placed in waterway. Therefore, trestles need to be avoided which leads to introduction of a hanging system. For this, existing Type E truss of the traditional SSS was modified to incorporate hanging arrangement (hangers and needle beams) instead of fabrication of new SSS. This modified SSS was analyzed using the finite element software LUSAS. The section capacities of the truss members were assessed under the applied loading and over-stressed members were satisfied by using enlarged sections. Finally, cost analysis for new and modified SSS was carried out. It was found that the later option was an economical solution compared to the earlier one. © 2015 Elsevier Ltd. Source

Local Authorities and Governments are under pressure to meet air quality and carbon emissions targets, however in several cases high level scale modelling outputs do not truly represent traffic conditions in local urban environments and associated hot spot pollutant concentrations which are determined by the built environment (canyons, road orientation, etc.). To address this gap in knowledge, Newcastle University recently developed an Integrated Database and Assessment Platform (NUIDAP), to bring together data from pervasive environmental and traffic monitoring systems with existing information, such as ITS and UTMC sources and traffic models. This paper presents the preliminary analysis and results that the Newcastle Team, with the support of AMEY, made using the software platform which integrates different data sources in order to identify problems, understand causes and formulate the solutions to air quality and manage traffic to alleviate, even prevent, pollution hotspots. This paper describes and presents evidence and results of the use of two types of microscale approaches for air quality assessment, the first using novel pervasive sensors, and the second employing modelling using an enhanced instantaneous emission model within the AIMSUN microsimulator. Scenarios modelled, including speed reduction and mode shift to public transport with reduction of traffic volumes, will be described and the outputs with and without the enhanced emission model are compared.

This paper shows how the private finance policy pursued by the UK government, applied to the delivery of highway maintenance services in Birmingham, provides a framework for the delivery of whole-life highways remediation, rehabilitation and maintenance needs at an affordable cost. Delivery of a best whole-life cost solution and the continual incentive to minimise expenditure results in a drive to optimise the use of physical and human resources, which in turn delivers environmental sustainability objectives. The £2.7 billion Birmingham highways maintenance and management service was also developed with local social and economic improvement in mind and this has shaped the interface with residents and engagement of the local supply chain in the delivery of the project.

This paper describes the findings of the experimental works undertaken to investigate the performance of zinc-rich paint (ZRP) to provide cathodic protection to chloride-contaminated RC structures. The program of experimental works was designed and conducted to assess four principal properties, viz (1) conductivity, (2) adhesion with concrete (short term and long term), (3) durability, and (4) electrochemical polarization. These properties considered together define the ability and effectiveness of the materials to act as an anode for impressed current cathodic protection. The research findings indicated that a specific proprietary ZRP product showed that optimum conductance was obtained with three coats producing a 280-320 μm thickness, with good adhesion to the concrete substrate, in which values obtained ranged between 1.65 and 3.5 MPa with and without applied current. It was capable of withstanding/supporting high levels of current, i.e., more than 300 mA/m2, and the service life of the ZRP coating was estimated to be well in excess of 20 years at an applied current density of 10 mA/m2. © 2015 American Society of Civil Engineers.
