Quality life and prosperous district is strongly connected with quality functional road infrastructure. One of the tools that can help is Pavement Management System. Pavement management system used in undermined area must take into account different degradation factors, which affecting disturbances on the roads. It is difficult to choose sufficient technology for its repair. Chosen repair should be from the economical and technological aspect as effective. This article refers to the gaps in the current pavement management system when its use in such affected areas. According to the long-term observation was made classification of roads disturbances and design of their repairs. This contributes significantly to obtain comprehensive knowledge of interactions between soil and road elements.

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.
