Asset Management Modules
Pavement Management Module: The Pavement Management Module provides
a systematic, consistent method for determining maintenance needs, priorities and the
optimal time of repair. Early detection and repair of a roadway distress are extremely
important in reducing long-term maintenance costs. Most pavements exhibit a
deterioration rate that accelerates as they reach advanced age. When examining
deterioration curves, it becomes clear that significant maintenance costs can be saved
if remedial action is undertaken prior to a roadway reaching the steep decline in
condition. The Pavement Management Module is used to track the life cycle of road
segments in the network and to highlight segments in need of attention.
In Network-Level--In Network-Level management, the entire roadway network is
considered for budgeting, planning, scheduling, and selection of maintenance projects.
Sufficiency Inspections are periodically conducted for all segments in a network. These
inspections are fast and easy observations of condition, geometry, safety, ride, etc.
Ideally, inspections should occur before the segment begins the sharp decline in
condition and at a point where timely maintenance can still be scheduled.
The Critical Pavement Condition Rating (PCR) value can be used to evaluate the need
for preventive and major maintenance. The critical PCR value occurs at the point
where the condition of a segment begins to deteriorate at an accelerating rate.
Typically, the maintenance costs increase dramatically once a segment reaches this
point. It is advantageous to begin maintenance efforts before the Critical PCR is
reached.
Today, upper management is more demanding of management techniques that
consider the needs of the entire network. With money in short supply, it is imperative
that the greatest benefits are achieved from each dollar expended. Network-Level
analysis complements Project-Level analysis to arrive at the required conclusions.
Deterioration : The Deterioration Matrixes within the AMS allows you to define a
Deterioration Curve that is associated with each Pavement Class. Once defined, these
Deterioration Curves can be referenced elsewhere in the PMS application. You may
create one Deterioration Curve for each Pavement Class.
A Deterioration Curve is a model of how the condition of segments that belong to a
Pavement Class will deteriorate over time (on the average). With a Deterioration Curve
defined for a Pavement Class, individual road segments can be compared to the curve
to determine performance/ life expectancy.
The Deterioration Curves are most accurate when they are developed from local
historical data.
Pavement Analysis Module: Assists in creating multiple CIP planning models and
“what if” type scenarios and Generates multi-year budgets and maintenance profiles.
Also assists in the preparation of MR&R decision trees, calculating cost vs. Benefit
scenarios, predicting
performance of individual assets, and aids in projecting funding to achieve overall
agency goals.
Safety Signage and Markings: Is a complete inventory of signs, mountings and
pavement markings. It yields a complete GPS/GIS location and identification for spatial
analysis and mapping of individual assets. It supplies a complete history log of events
with attached images and videos. It also supplies queries, reports, and cost of materials
analyzes along with access to predefined sign and marking libraries.
Bridge and Culvert Module: It provides a complete bridge and culvert inventory along with inspection records by
category. It provides a complete structure history with database rollback queries and
reports. Also, provides full English and Metric support, while maintaining a complete
structure inventory and appraisal information (si&a). It also supplies complete support
for FHWA, NBI and PONTIS data.
Asset Manager Module: It is the “Workhorse” of all of the AMS for it serves as a clearing house for all managed
assets. Records labor, equipment and material costs. It relates work activities to
specific work orders. It projects and tracks maintenance schedules. It furnishes
customized queries and reports while tracking inventory levels. It also tracks public
complaints and generates work requests/orders. It may contain standard operating
procedures (Cook Book) for most all types of maintenance work. This is truly the “work
horse” of the system.
New Techniques and Developments
Voice Activated Data Collection: It provides vocabulary building capabilities and
GPS on the fly locations. Captured data downloads data directly into predefined data
bases with no more manual data input except for QA/QC. This technology speeds up
the data collection and data processing by about 3x.
Voice Recognition Technology 101: It interprets spoken words and converts it to
text while associating an asset or other item with their exact physical location via
GPS/GIS. It stores data in an RDBMS using key fields to relate one record with another.
One simply tells the laptop field computer what you see and it will record the field data
as defined in the vocabulary dictionary. In the office one downloads the data to your
office computer and performs QA/QC to check the accuracy of data being exported to
the proper asset management module.
