NYSDOT 2021 DPS data collection update Brendan Rock, P.E. NYSDOT Materials Bureau TPF-5 (443) Meeting November 10, 2021 1
2 2020 - 2022 2020 DPS was included on 3 jobs Called for data collection over the entire mat, reported in 100ft segments. 2021 DPS was included on ~11 jobs 2022 Look to continue increasing the frequency of use and include special specification on D contracts This year we called for 1 mile or 50% of paved area whichever was greater. Added a required summary sheet indicating core density, nuclear gauge readings, and DPS measurement at core locations. Reducing required number of pucks
3 Continued work Developing data expectations from a QA point of view Further develop the summary reports and scale back the amount of data collected to reflect acceptance style testing rather than a QC testing. Active promotion NYSDOT regions Contractors Consultants Producers Evaluating Trends Databasing all our data to evaluate trends in the comparisons between the DPS, cores, and nuclear density measurements
6 Developments New resource investments in NYSDOT s program Reorganized some of Material Bureau to allow for a work group to dedicate more substantial time to DPS and other GPR activities Statistical modeling of data We are in the early stages of developing our statistical model for the data. 100ft segment density histograms.
7 Challenges Limited resources for data collection With the increase in number of jobs this year we are starting to reach the limit of our consultant s capacity. 1 consultant with 2 meters. Data turnaround time Developing more specific summary pages puts more processing time on the consultant which will delay receiving the data Developing specification requirements Investigation of unexpected field data
