An effective pavement management system requires a comprehensive pavement preservation strategy (PPS). Wisconsin’s PPS is guided by a philosophy whose goal is to optimize pavement performance to provide the highest quality service to the customer per unit of expenditure. The PPS is customer-oriented and views “service” in terms of user comfort, convenience, and safety. The strategy is broad-scoped and considers all pavement management activities, from “do nothing” to reconstruction. Wisconsin’s PPS has program values that are based on solid research that has been field verified. The treatment alternatives recommended for any particular pavement problem address the causes, not the symptoms, of that particular problem—thus, the root cause of the problem is addressed, and funds are not used to treat merely a symptom. Accordingly, the PPS is termed a cause-based instead of a schedule-based strategy (applying treatments on a predetermined schedule), or a “worst first” strategy (treating the worst pavements first). The PPS follows a logical progression through a series of evaluations to convert a set of raw, field-collected data (ride and distress) to, ultimately, a set of recommended actions. The process moves from raw data to an evaluation of the level of the distress. Combinations of distress levels are used to identify specific pavement problems. In turn, these pavement problems are evaluated as a family to generate appropriate, cost-beneficial solutions.

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.

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.

Maintenance and rehabilitation (M&R) scheduling for airport pavement is supported by the scientific literature, while a specific tool for heliport pavements lacks. A heliport pavement management system (HPMS) allows the infrastructure manager to obtain benefits in technical and economic terms, as well as safety and efficiency, during the analyzed period. Structure and rationale of the APSM could be replicated and simplified to implement a HPMS because movements of rotary-wing aircrafts have less complexity than fixed-wing ones and have lower mechanical effects on the pavement. In this study, an innovative pavement condition index-based HPMS has been proposed and implemented to rigid and flexible surfaces of the airport of Vergiate (province of Varese, Italy), and two twenty-year M&R plans have been developed, where the results from reactive and proactive approaches have been compared to identify the best strategy in terms of costs and pavement level of service. The result obtained shows that although the loads and traffic of rotary-wing aircrafts are limited, the adoption of PMS is also necessary in the heliport environment.
