The term "pavement maintenance" can refer to a variety of tasks, from straightforward cleaning or restriping to repairing serious issues like potholes and washouts. Depending on whether the emphasis is on correcting distresses or preventing them from happening in the first place, maintenance can also encompass a variety of ways. We will go over the fundamental idea of pavement care and the various kinds of tasks that fall within its broad definition.
Extending the pavement's life is an aim shared by all maintenance procedures. More and more pavements are being built with longer service lifetimes in mind, which means there will be more opportunities for maintenance during the pavement structure's lifetime. The life cycle cost of a long-lasting pavement must be lower than that of conventional alternatives, considering both the cost of initial construction and ongoing maintenance throughout the pavement's useful life. In this method, reducing the expense of pavement upkeep is beneficial to the design's success and feasibility. However, the maintenance activities must be efficient in terms of cost. This does not necessarily imply that maintenance should be performed less frequently.
Different Types of Pavement Upkeep The concept of pavement maintenance is frequently discussed in relation to related subjects like pavement preservation, restoration, and reconstruction. There are various categories of pavement maintenance activities. It is helpful to have a general understanding of how these phrases are employed in order to comprehend pavement maintenance; otherwise, they may appear overlapping and confusing.
Programs and actions that use a network-level, long-term strategy to improve the performance of pavements by implementing a cost-effective, integrated set of practices that prolong pavement life and increase safety are referred to as pavement preservation. Rehabilitating an existing pavement involves making structural changes to increase the pavement's load-bearing capacity and/or extend its useful life.
Reconstruction of the pavement means removing the entire present pavement structure and replacing it with one that is either larger or equivalent.
A planned approach of affordable Asphalt repairs to an existing road system and its ancillaries that preserves the system, delays further deterioration, and upholds or improves the system's functioning state is known as preventive maintenance.
Corrective maintenance Actions taken in reaction to the emergence of a deficit or inadequacies that adversely affect the facility's ability to operate safely, effectively, and in the long run, without compromising the integrity of the pavement section.
Routine maintenance Tasks that are scheduled and carried out regularly to protect and maintain the system's condition.
Protection and Restoration To ensure that roads are always in good condition and that distresses are never present, pavement maintenance should ideally be primarily preventive. This can be done affordably with the aid of a pavement management system and a well-planned maintenance schedule. At the same time, it is a good idea to make sure you can repair things when they break. This will enable you to respond to unforeseen changes and preserve the system's structural integrity. One could argue that a comprehensive pavement maintenance strategy should include both prevention and repair.
