The Pavement Management System sub-unit has primary responsibility
to develop and implement a pavement management system for North Carolina that
meets the Federal Highway Administration's mandate for an operational pavement
management system.
This group analyzes the information collected in the pavement
condition survey. Pavements are rated based on various distresses that occur
on each section of pavement. The pavement sections are then prioritized from
worst to best based on the ratings. A recommended treatment is also given for
each deficient section to bring it up to an acceptable level. The treatments
recommended are to be used as a guideline. Due to many different conditions
because of variations in location, traffic, and the distribution of distresses
in the section, other methods of treatment may be more suitable for a certain
pavement section. Each section should be evaluated before rehabilitation to
determine the best method of treatment.
Each division has been provided the results of the pavement
condition survey in a spreadsheet form for use by the field. Like projects (crack
sealing, patching, etc.) can be requested by location from the spreadsheet for
organizing work groups to perform certain functions. This section will be happy
to come to your county and demonstrate how to use the spreadsheet.
The group has also been looking at past performance of pavement
and being able to predict the remaining life of each pavement section.
The past history of each section's condition can be accessed along with a graph
showing the past condition and the predicted performance. This information can
be used in determining which of two projects with the same rating should be
resurfaced first. For example, if two sections have a rating of 65 and
one is predicted reach a rating of 50 in two years and the other is predicted
to reach 50 in four years and funds are only available to do one section, the
one with the most rapid declining condition should receive attention first.
