staff and Deighton to develop a Remaining Service Life (RSL) analyses for PMS
summary reporting to the FHWA and the State Legislature.
In an effort to maintain high levels of expertise with in the NJDOT's Pavement and
Drainage Management Systems Unit, the Pavement Resource Program will develop a
PMS procedures manual including the data management, performance models,
decision trees, economic analysis, and reporting of the Deighton Infrastructure
management system and provide ongoing technical support and training of the unit
personnel in the operation of the Deighton PMS. To assist with the implementation of
the new PMS and training of the NJDOT staff, the Pavement Resource Program used
the expert oversight of Katie Zimmerman of Applied Pavement Technology, Inc. The
Pavement Resource Program would continue to use the Deighton experts to address
the NJDOT's needs through ongoing maintenance and support agreements.
Work Performed
During the early stages of the project, the PRP worked with Deighton to develop a
maintenance agreement. The PRP also worked with Deighton and the NJDOT staff
during site visits to refine the dTIMS PMS to incorporate committed projects, 2008
pavement condition data, and refine the pavement analysis sections. The PRP staff
also worked to develop a NJDOT Deighton dTIMS PMS manual for future users of the
system. The user manual would be reviewed and accepted by the PRP, Deighton
support staff, and the NJDOT PMS staff. (Appendix A) The staffs also worked diligently
on revising the analysis segments of dFrag analysis for additional analysis runs.
The PRP worked with Deighton and NJDOT to evaluate modifications to the dTIMS
PMS section definitions to be New Jersey specific. They also met to evaluate the
budget scenario results for the 2010-2020 program. The highway definitions were
modified due to changes in the Straight Line Diagrams (SLD) descriptions. Some
section definitions were adjusted based on 2010 pavement condition data. The current
2010 pavement condition data was inputted into the dTIMS.
Ride Quality of New and Rehabilitated Pavements
Background
The Pavement Resource Program agreed to continue providing technical support to the
NJDOT Pavement and Drainage Management Systems Unit by working with the unit
staff in establishing and implementing calibration procedures, and assist in
management of a proposed NJDOT International Roughness Index (IRI) calibration and
certification facility (based on the Texas TI model). The Pavement Resource Program
would develop a procedures manual for data collection and analysis of calibration of
high speed profilers based on the NJDOT's standard walking profiler. The Pavement
Resource Program agreed to facilitate training of NJDOT and industry staff on the use
of high speed and portable profilers to enhance pavement and bridge deck ride quality.
