Abstract:A critical role of pavement management is to
provide decision makers with estimates of the
required budget level to achieve specific steadystate
network conditions, and to recommend the
best allocation of available budget among
competing needs for maintenance, rehabilitation,
and repair (MR&R) projects or among different
networks such as among Districts.
The Ohio Department of Transportation
(ODOT) has developed a comprehensive
Pavement Management Information System
(PMIS), which provides a collection of tools to
support pavement management activities. These
tools include reporting of current condition and
deficiency, predicting future pavement
condition, and estimating remaining service life
(RSL). Predicted future pavement condition and
estimated RSL allow decision makers to perform
“what-if” analysis of the financial impact and
level of service provided by a multiyear MR&R
work plan. However, given the size of the
pavement network and the number of competing
project candidates, the number of feasible
alternative work plans can be very large. A
procedure that can quickly narrow down the
alternatives is highly desirable.
