Conduct laboratory and field testing of materials for characterization of pavement
structures and their individual components for roadways under NJDOT
jurisdiction to support the MEPDG material inputs.
Develop a consolidated list of inputs for MEPDG for levels 1-3
Organize meetings with NJDOT traffic organizations to discuss traffic data needs
and modification to consultant agreement for data collection.
Develop a NJ-LTPP program to assess the pavements designed with the new M-
E Pavement Design Guide (MEPDG) to determine the "as constructed" level 1
inputs for the MEPDG and enhance the predicted pavement performance models
for 00, top down and bottom up cracking and rutting.
Work Performed
Two of the MEPDG test sections (I-195 and I-287) were cored and sampled. Site
specific traffic data and Falling Weight Deflectometers (FWD) were conducted and
analysis was performed. The extracted HMA cores from the I-195 section were tested
for dynamic modulus, asphalt binder properties, volumetrics, and gradation. The test
data from the cores was used to populate the required material properties in the
MEPDG for the asphalt mixtures. The back-calculated modulus values from the FWD
were used as modulus inputs in the MEPDG.
The PRP collected materials (asphalt mix and binder) produced for the jobs being
placed and testing was conducted on the materials to enable the PRP to collect
pavement distress data and the generation of the pavement distress prediction models.
Non-Destructive Equipment
Background
The Infrastructure Condition Monitoring Program (ICMP) group agreed to increase its
support and services for various NJDOT units. The objective was to develop and deploy
the latest NDE/NDT technologies for evaluating and monitoring the condition of the
transportation and utilities infrastructure and assist with Transportation Asset
Management.
Work Performed
The PRP continued to analyze the input of Ground Penetrating Radar (GPR) into the
HPMA. Missing sections were identified by the staff of PRP and GPR data for those
sections was collected, analyzed, and inputted into the HPMA.
Geographic Information Systems (GIS)
Background
The Pavement Resource Program agreed to continue to provide technical support to
the NJDOT Pavement and Drainage Management Systems Unit by working with the
unit staff in establishing and implementing Arc GIS layers for subgrade soil type
locations (Rutgers Soils Maps), material characterization, and properties. These
