Reimagining Infrastructure Megaproject Delivery: An Australia—New Zealand Perspective

Ninan, Dr Johan (author), Clegg, Stewart (author), Burdon, Steve (author), Clay, John (author)

Infrastructure megaprojects are increasing in size and number worldwide. Widespread shortcomings such as cost overruns, delays, litigious threats, and community opposition are now so pervasive there is a clear mandate to rethink the way we plan, deliver, and operate our infrastructure. In this context, we situate this research to understand how...

Investigation of Polyurethane Modified Cold Bitumen for Fast Cold In-Place Recycling

Lin, P. (author), Liu, X. (author), Erkens, S. (author), Welvaarts, Bart (author), Brouns, Koen (author)

Cold in-place recycling is gaining more attention worldwide because of its lower energy consumption, while the normally used asphalt emulsion and foamed asphalt cannot meet this requirement of short traffic disturbance and road performance of the surface layer. In this research, a polyurethane-modified cold binder (PMCB) was designed and...

Five golden principles to advance marine reef restoration by linking science and industry

ter Hofstede, R. (author), Bouma, Tjeerd J. (author), van Koningsveld, M. (author)

Marine reef ecosystems have degraded massively worldwide, and restoration efforts have as yet not managed to realize the scale required to reverse continued degradation. To achieve effective scales, scientific insights in restoration methods should be paired with industry-based approaches used for infrastructural development. We illustrate by...

Proof Load Testing Method by the American Association of State Highway and Transportation Officials and Suggestions for Improvement

de Vries, R. (author), Lantsoght, E.O.L. (author), Steenbergen, Raphaël D.J.M. (author), Naaktgeboren, Marius (author)

Because of the aging of infrastructure, methods are explored by which the reliability of existing bridges and viaducts can be assessed. In cases in which limited information of the structure is available or its condition is of concern, proof load testing may be used to demonstrate sufficient live load carrying capacity. Proof load tests in...

First-Year Field Performance of Epoxy-Modified Asphalt

Jing, R. (author), Apostolidis, P. (author), Liu, X. (author), Erkens, S. (author), Scarpas, Athanasios (author)

Pavement materials containing epoxy-asphalt are mainly used to enhance the fatigue cracking resistance of surfacing layers on bridges. These materials have also been proposed for roadways, but limited field data are available. In this research, a fully instrumented epoxy-modified asphalt surfacing layer was applied to measure strain responses in...

Enhancing the resilience of drinking water infrastructures

Kloosterman, Ritsche Anne (author), Herder, P.M. (author), van der Hoek, J.P. (author)

Long term uncertainties in combination with long lifetime of assets of drinking water infrastructures (DWIs) and changing expectations of stakeholders make strategic decisions in drinking water infrastructures (DWIs) complex. A framework with building blocks and design spaces was developed to support these decisions. Building blocks, divided in...

Challenges of integrated multi-infrastructure asset management: a review of pavement, sewer, and water distribution networks

Daulat, Shamsuddin (author), Rokstad, Marius Møller (author), Klein-Paste, Alex (author), Langeveld, J.G. (author), Tscheikner-Gratl, Franz (author)

The prosperity of urban life is dependent on its infrastructure. Urban underground infrastructure components (assets) are aging and need regular monitoring, maintenance and rehabilitation. These assets are often placed under pavements and in close vicinity to each other. Managing them in a coordinated way is rational considering costs and...

Polder pumping-station for the future: designing and retrofitting infrastructure systems under structural uncertainty

Timmermans, Jos (author), van Druten, Emiel (author), Wauben, Marcel (author), Kwakkel, J.H. (author)

In designing and retrofitting infrastructure systems, engineers are increasingly confronted by uncertainties about the future operating conditions of these systems, stemming from climate change or rapid socio-economic development. Particularly for long-lived capital-intensive infrastructure components like pumping stations, current...

Probabilistic life cycle cash flow forecasting with price uncertainty following a geometric Brownian motion

van den Boomen, M. (author), Bakker, H.L.M. (author), Schraven, D.F.J. (author), Hertogh, M.J.C.M. (author)

In the Netherlands, probabilistic life cycle cash flow forecasting for infrastructures has gained attention in the past decennium. Frequencies, volume and unit prices of life cycle activities are treated as uncertainty variables for which an expert-based triangular distribution is assumed. The current research observes the absence of time...

Understanding urban infrastructure via big data: the case of Belo Horizonte

Ersoy, A. (author), Chaves Alberto, Klaus (author)

One major impact of the global economic crisis is the way it has deepened inequalities around the world. Infrastructure remains essential within this debate as it provides wider health, economic and environmental benefits for society beyond the conventional calculations of cash returns. With the potential exploration of big data, cities now face...

Societal Burden and Engineering Challenges of Ageing Infrastructure

van Breugel, K. (author)

Ageing is an inherent feature of nature and, hence, of materials, structures and systems. Yet, it seems a rather new topic in both science and engineering. The main reason for increasing attention for ageing as a topic is the growing awareness that, particularly in industrialized countries, ageing of our assets is a financial burden for the...

Smart cities as a mechanism towards a broader understanding of infrastructure interdependencies

Ersoy, A. (author)

Cities are centres of innovation, but they also face great challenges such as rapid urbanization, climate change and increased pressure on city services. While working in partnership has been considered as an essential element in urban management, the increasing interconnected nature of infrastructure networks has provided opportunities for...

How housing, infrastructure and water determined the spatial structure of the Randstad

Priemus, H. (author)

Between 1950 and 1990, housing was the driving force behind the spatial growth of the Randstad. Growth poles (1970s) and later VINEX locations (1990–2010) were the main components of growth management. Transport infrastructure has developed greatly since the 1920s. Since 1990, infrastructure development has increasingly become the structuring...

Climate change in asset management of infrastructure: A risk-based methodology applied to disruption of traffic on road networks due to the flooding of tunnels

Huibregtse, E. (author), Morales Napoles, O. (author), Hellebrandt, L. (author), Paprotny, D. (author), De Wit, S. (author)

This paper presents a risk-based method to quantify climate change effects on road infrastructure, as a support for decision-making on interventions. This can be implemented in climate adaptation plans as an element of asset management. The method is illustrated by a specific case in which traffic on a road network is disrupted by the flooding...

A Matter of Relationships: Actor-Networks of Colonial Rule in the Gezira Irrigation System, Sudan

Ertsen, M.W. (author)

In the first half of the 20th century, colonial rulers, a British firm and Sudanese farmers changed the Gezira Plain in Sudan into a large-scale irrigated cotton scheme. Gezira continues to be in use up to date. Its story shows how the abstract concept 'development' is shaped through the agency of humans and non-humans alike in government...

Urban landscape infrastructures: Designing operative landscape structures for the built environment

Nijhuis, S. (author), Jauslin, D.T. (author)

This paper explores infrastructure as a type of landscape and landscape as a type of infrastructure. The hybridisation of the two concepts, landscape and infrastructure, seeks to redefine infrastructure beyond its strictly utilitarian definition, while allowing design disciplines to gain operative force in territorial transformation processes....

Data Infrastructures for Asset Management Viewed as Complex Adaptive Systems

Brous, P.A. (author), Overtoom, I. (author), Herder, P.M. (author), Versluis, A. (author), Janssen, M.F.W.H.A. (author)

Data infrastructures represent information about physical reality. As reality changes, data infrastructures might also be subject to change. Researchers have increasingly approached physical infrastructures as being complex adaptive systems (CAS). Although physical infrastructures are often approached as CAS, the underlying data infrastructures...
