Dynamic Pavement Response Data Collection and Processing at the NCAT Test Track

In the 2003 test cycle at the NCAT Test Track, a structural experiment was included to investigate dynamic pavement responses under live truck loading. Instrumentation was installed in different layers of the pavement structures in sections N1 through N8. Data from the instruments are collected in two ways: a data logger records at a low sampling frequency (i.e., one reading per minute) and aggregates the data into an hourly basis, 24 hours a day; and a high frequency data acquisition system is used to collect dynamic data of specific truck passes. The objective of this report is to provide an explanation of the high frequency data collection and processing procedure currently used at the Test Track. Future reports will provide much deeper and more comprehensive analyses of the relevant pavement response data. The figures included in this report are from data collected on November 7, 2003. Data were collected on a sunny morning, and pavement surface temperatures increased from 85 to 102 degrees F during the testing period.
