Abstract
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.
Highlights
Since the 1970s, pavement management systems (PMS) have been applied to roads and airports, and currently, they are considered a good and useful aid for the infrastructure manager [1,2,3,4]
With the introduction of the PMS, the importance of monitoring the pavement conditions and planning the Maintenance and rehabilitation (M&R) has been understood and implemented, and the adoption of the best alternative among the available ones is a consequence of these actions [6]
The main objective of this study is the implementation of a heliport pavement management system (HPMS) to assess the pavement condition through visual surveys according to the American Society for Testing and Materials for roads [22] and airports [23]
Summary
Since the 1970s, pavement management systems (PMS) have been applied to roads and airports, and currently, they are considered a good and useful aid for the infrastructure manager [1,2,3,4]. A PMS provides a systematic and consistent method for assessing the current state of a pavement, predicting its future condition, determining priorities and the optimal time for repair, and selecting maintenance or repair and rehabilitation (M or R&R, respectively) needs [5]. This process has overturned how to approach the maintenance of transport infrastructure pavements. The methodology of system dynamics could support PMS in order to identify the interrelationship between the elements of the systems, to distinguish causes and effects, and to investigate which parameters are pivotal to improve the system’s behavior [7]
