Being able to undertake more efficient maintenance and renewal planning of road networks has seen a number of pavement management systems (PMS) being developed between the 80s to mid-90s. During the initial years, there was a significant focus on substantiating the need and demonstrating the benefits of using these tools to assist in the investment planning for roads. Today, with substantial experience, and legislative support such as MAP-21 and PASS-55, the use of PMS in the asset management cycle of roads is a given. The challenge these days is to effectively use these tools and ensure robust outcomes are achieved from the overall PMS process. The success of any PMS is determined by a number of factors including having skilled resources, institutional support, and legislative and funding drivers demanding evidence-based forecasted investment needs. Asset managers also realize the importance of having technical robustness in the process to ensure likely outcomes. This paper documents the evolutionary development pathway of the New Zealand PMS that has now been in use across the entire country for more than 18 years. It shows how by always challenging the status quo it has resulted in consistently increasing the overall robustness of the system. In particular, it shows how different validation techniques have been used to improve the practicality and appropriateness of long-term forecasting capabilities.

The Authors describe the role of non-destructive deflection tests in Airport Pavement Management System (APMS) presenting the experience developed at an Italian Airport. An original approach to APMS implementation is illustrated, based on the PDCA cycle for quality control and continuous improvement of processes. An example application for the management of the runway pavement is described. Deflection test results obtained in four tests campaign carried out over a ten years period were globally analyzed to obtain pavement bearing capacity evolution and demonstrate the effectiveness of cyclic approach to pavement management. It is showed that structural evaluation can be an invaluable tool in pavement management and assist planning activities in the medium and long term.

Concerns over the condition of water and sewerage networks and their facilities are especially topical as several countries, including Finland, are approaching a stage where their aging and deteriorating pipelines will demand extensive repair, renewal and replacement. Solving the problems related to the construction and, in particular, the maintenance of water service infrastructures requires the methods of long-term planning and strategic decision-making, which are often referred to as water utility asset management. Since maintaining the operational capacity of water service systems has a crucial role in preventing hazards to human health and to the environment, the policy-level consideration of issues related to asset management planning seems well justified. A review of the institutional governance of asset management and investment planning in countries that are facing similar challenges provides several replicable principles for the water sector in Finland. A combination of legal requirements and professionally established norms could be expected to set an appropriate balance between securing adequate service levels and allowing utilities to decide autonomously on additional improvements.

A pavement management system (PMS) can assist decision makers in finding optimum strategies for maintaining pavements; however, local agencies in small communities often face implementation challenges, such as a limited budget, lack of manpower and technical resources, and insufficient and inaccurate data. The available literature focuses on the general process of establishing and implementing PMS for small communities but does not discuss specific solutions in detail. Madison, South Dakota, is used as a case study in this article to discuss the issues small communities face in creating PMS, and to present practical, cost-effective solutions. The intent is to transfer and advance the knowledge surrounding the preservation of pavements and promote the use of PMS in small communities.

The commercialization of university-based research occurs to varying degrees between academic institutions. Previous studies have found that multiple barriers can impede the effectiveness and efficiency by which academic research is commercialized. This case study was designed to analyze the status of the commercialization activity at the University of Kentucky via a survey and interview with a successful academic entrepreneur in order to determine the impediments the individual perceived during the commercialization process. The study also garnered insight from the individual as to how the commercialization process could be improved. Issues with infrastructure were highlighted as the most significant barrier faced by the individual. The research subject also suggested that commercialization activity may generally increase if a number of factors were mitigated. Such insight can be communicated to the administrative leadership of the commercialization process at the University of Kentucky. Long term, improving university-based research commercialization will allow academic researchers to be more active and successful entrepreneurs such that intellectual property will progress more freely to the marketplace for the benefit of inventors, universities, and society.

A modern Pavement Management System (PMS) should be essential for maintenance a metropolitan urban road network. Municipality of Budapest has developed own management system for their road pavement operation. To an efficient outcome the newest methods are used for the data collecting with the most innovated geo-informatics solutions, which are help us in our multi criteria decision making process. We present a degradation model which useful for the prediction of the roughness, yielding surface condition of the pavement in the future. After the whole data evaluation we give accurate information about the general characterization of the permanent road network conditions. Our paper shows that in all modern asset management system based on multi criteria decision making processes, which contain single or multi objective optimization methods. The PMS based on the available-technical and financial data and its optimization process provides a pavement renovation offer for each road in Budapest transportation network and finally the paper presents how can we ranking the invention list from our optimization process.

The Metropolitan Transportation Commission pavement management system (MTC PMS) has been used by many cities and counties in the United States for more than 15 years. MTC PMS was evaluated to determine the extent to which the software can support the Governmental Accounting Standards Board (GASB) 34 reporting requirements, established in 1999. A local agency PMS can take information from a pavement network database to produce useful reports, which can be utilized jointly with the information from other assets managed by an agency to support the requirements for a comprehensive asset management system and other reporting requirements. The objective of this study was to elaborate GASB 34 requirements for reporting infrastructure assets, examine the capabilities of MTC PMS in supporting those standard requirements, and recommend any modifications of MTC PMS needed to better support GASB 34. It is evident from the study that MTC PMS has the capability, to some extent, of supporting GASB 34 for reporting on a pavement network according to both the GASB 34 reporting methods: the depreciation method and the modified approach. It partially supports the prerequisites for using the modified approach, which require that the managing agency have an asset management system with certain designated characteristics. Some modifications of MTC PMS software were proposed to make this management system more effective as a tool supporting an asset management system and overall GASB 34 requirements.

One of the main challenges for road authorities is to maintain the quality of the road infrastructure. Road anomalies can have a significant impact on traffic flow, the condition of vehicles, and the comfort of occupants of vehicles. Strategies such as pavement management systems use pavement evaluation vehicles that are equipped with state-of-the-art devices to assist road authorities in identifying and repairing these anomalies. The quantity of data available is limited, however, by the limited availability and, therefore, coverage of these vehicles. To address this problem, several investigations have been conducted on the use of smartphones or equipping vehicles with additional sensors to identify the presence of road anomalies. This paper aims to add to this arsenal by using sensors already available in production vehicles to identify road anomalies. If production vehicles could be used to identify road anomalies, then road authorities would be equipped with an additional fleet of mobile sensors (vehicles traveling on a particular road) to receive initial insights into the presence of anomalies. This information could then be used to assist road authorities to deploy their staff and equipment more precisely at these locations, such that appropriate equipment reaches the right place at the right time. In this paper, an algorithm that uses lateral acceleration and individual wheel speed signals, which are commonly available vehicular variables, was developed to detect potholes using machine learning techniques. The results of the algorithm were validated with real life test scenarios.

Abstract Typically, large-scale irrigation systems are built almost entirely in a short time-frame, a significant part of the assets age at the same time and concentrated investment needs for rehabilitation are predictable. This paper focuses on planning these needs in an aggregated way, providing a big picture for the long term investment plan. A methodology for this purpose was developed and applied to a large-scale irrigation utility in Portugal. For such, the following steps were taken: (i) system breakdown by functional areas; (ii) infrastructure components disaggregation; (iii) diagnosis of the reference situation; (iv) evaluation of long-term alternatives for rehabilitation investment planning. The methodology is in line with the IAM approach recommended by IWA and the ISO55000 standards. In this paper, the specificities of this particular application, namely a proposal of irrigation component classes, and the studied alternatives, are presented. As an overall result, it was possible to indicate a path for economic sustainability without committing the infrastructure sustainability: it is based on gradual replacement of the assets reaching their useful life, combined with a constant rehabilitation rate. This paper is a contribution to an AM system for irrigation utilities, so alignment with IAM and the contribution to a broader IAM system is highlighted.

Reporting assets is an essential component of an asset management system. While asset management covers management of the whole range of assets an agency owns, several types of reports need to be produced depending on the types of assets and the purpose of reporting. These reports are used to convince lawmakers and taxpayers to allocate funds needed to keep the assets in a desirable condition. Reports produced from an individual management system, such as a pavement management system (PMS), a bridge management system, or a sewer management system, can be combined to support reporting on all assets combined. A study was conducted to demonstrate the production of asset management reports by using a local agency PMS. The study was conducted by using the Metropolitan Transportation Commission PMS, which is used by many local agencies to support managing pavement networks of cities and counties. It is evident from the study that several useful reports supporting an overall asset management system can be created by using this PMS.

The process of selecting road maintenance technologies for the Pavement Management System (PMS) can use road pavement moduli of deformation as the substantiating information. Assessment criteria based on either pavement or base course moduli of deformation have strong empirical underpinning, since the stiff plate bearing testing (SPBT) is commonly used worldwide. This paper discusses potential practical applications of plate bearing test numerical simula­tion based on Falling Weight Deflectometer (FWD) deflection data, and theoretical model based on flexible pavement. It was proven that including a pavement model with stress dependency, the simulated second load-displacement curves meet reliably plate bearing in-situ test conditions for different layers of either subgrade or base courses of road pave­ment. This methodology is feasible by classifying technical condition of each lower layer of road pavement against requirements towards new pavements.
