Pavement Management
Tasks and Responsibilities:
- Collect network level data including ride, rutting, geometrics
and video on about 9000 miles of public highways using an Automatic
Road Analyzer (ARAN).
- Collect data, with the ARAN on airport runway condition's for
32 airports statewide.
- Contribute to the assembling of the BTIP, 6-year plan and 20-year
plan.
- Analyze data collected, and maintain dTIMS-CT database on the
condition of the highway system.
- Collect project level and special request data for such things
as shim quantities, ride and existing geometrics.
Pavement Management
Defined:
A Pavement Management
System is a set of tools that assist planners and designers in optimizing
the effectiveness of pavement expenditures. The function of Pavement
Management is to collect and analyze pavement condition data to
improve the efficiency of decision-making and provide feedback on
the consequences of decisions. This is accomplished by providing
timely recommendations on treatment alternatives and locations to
protect the current investment in highways and to reduce users costs.
The goals of Pavement Management are to maintain the present average
network condition, prevent increases in deficient and unacceptable
highways, and maintain the present distribution of conditions within
each system. The philosophy of Pavement Management is to first keep
“adequate” (built) highways in good condition and then
improve “inadequate” (backlog) highways as funding allows.
An “adequate” highway, for the purpose of Pavement Management,
is one that meets or exceeds structural and geometric standards,
but does not necessarily meet capacity needs. An “inadequate”
highway fails to meet structural or geometric standards.
Pavement Condition Ratings
(PCR) and Road Condition:
Pavement Condition Ratings
are not necessarily indicative of road condition. PCR's are an inventory
of distresses in pavement only ,such as cracking, wheel path rutting,
and longitudinal profile (Ride). PCR's do not account for base material,
shoulders, or drainage. A section of 'Backlog’ road could have
a new pavement as a holding action until Rehab or Reconstruction
can take place. This paving will have a short life span compared
to a structural preservation overlay on a 'Built' highway. PCR's
will always range from 5 for a newly paved roadway to 0 for a road
that is completely deteriorated. It is generally most cost effective
to treat a road before the PCR drops below a rating of 3.
