Optimizing Pavement Preservation into a Pavement Management System

Pavement preservation is a cost effective way to extend a pavement’s life, improve safety and improve pavement service condition. There are many benefits of adding pavement preservation into a pavement management system (PMS). PMSs can be used to identify pavement preservation needs and help program pavement preservation projects. Pavement preservation increases the effectiveness of a PMS, which can allocate available funding more cost-effectively. This paper primarily provides guidance on how to integrate the pavement preservation components to PMSs at both the project and network levels. This paper also shows that in the network level, a PMS can optimize the allocation of funding between pavement preservation and rehabilitation projects to achieve the highest return with different funding levels. It utilizes the network-wide pavement condition index (PCI) driven method to optimize the network. In addition, it can achieve a multiple objectives multiple criteria optimization for a PMS with pavement preservation components.
