FOREWORD

This report documents the reinterpretation of the dynamic load response (DLR) traces for selected Long-Term Pavement Performance (LTPP) test sections in Ohio. The report also describes the work performed to correct data issues such as trace peak time lag shifts, sensor locations, and wheelpath offsets for asphalt concrete and portland cement concrete pavements. The reinterpreted DLR data have been made available in the LTPP program's Standard Data Release 27.0 and later versions.(1) This new LTPP DLR data will serve as a unique resource for researchers in investigating the dynamic interaction between truck axle loads and pavements, validating their pavement dynamic loading models, and developing mechanistic pavement performance prediction models.

16. Abstract

The dynamic load response (DLR) Study Team reinterpreted 4,290 Ohio Specific Pavement Studies (SPS)-1 (asphalt concrete pavements) raw traces and 9,240 Ohio SPS-2 (portland cement concrete pavements) raw traces, correcting the data issues identified by Long-Term Pavement Performance (LTPP) data analysis/operations feedback reports and the technical memorandum, Investigation of Ohio DLR data in LTPP Database for LTPP Standard Data Release (SDR) 22.0, including trace peak time lag shifts, incorrect sensor locations, and wheelpath offsets. (See references 2-6.) The team calibrated and smoothed the SPS-1 and SPS-2 raw traces before categorizing those traces into three categories: good, maybe, and not good. For the SPS-1 data, approximately 24 percent of strain gauge traces, 55 percent of linear variable differential transformer (LVDT) traces, and 99 percent of pressure cell traces were categorized as good. For the SPS-2 data, only smoothed traces were categorized due to significant noise in the raw traces. Approximately 61 percent of strain gauge traces and 15 percent of LVDT traces were categorized as good. Only good traces were used for further extraction of trace peaks and valleys for SDR 27.0.(1) In addition, the sensor locations and the corresponding wheelpath offsets were also corrected.

 

The reinterpreted DLR data resolved the data issues and have been published in SDR 27.0.(1) To aid future DLR data users in identifying the layout and status of each sensor from one test visitorrun to another, appendices A through E show the sensor layouts in the Ohio SPS-1 and SPS-2 DLR test sections as well as the results of the 23 Ohio SPS-1 DLR tests and the 24 Ohio SPS-2 DLR tests.
