Abstract:"Many important decisions are necessary in order to effectively provide and manage a pavement network. At the heart of this
process is the prediction of needed future construction events. One approach to providing a single numeric on the condition
of a pavement network is the use of pavement remaining service life (RSL). However, many issues exist with the current
RSL terminology and resulting numeric that complicate proper interpretation, interagency data exchange, and use. A major
source of uncertainty in the current RSL definition is the use of the term “life” to represent multiple points in the pavement
construction history. The recommended path to consistency involves adopting terminology of time remaining until a defined
construction treatment is required (i.e., RSL is replaced by remaining service interval (RSI)). The term “RSI” has the ability
to unify the outcome of different approaches to determine needs by focusing on when and what treatments are needed and
the service interruption created. This report provides step-by-step guidelines for implementing the RSI terminology. A
companion report presents the framework for replacing the current RSL terminology with one based on more exact
construction event terms."
