Pavement Testing Facility -- Phase 1 Final Report
The Pavement Testing Facility (PTF) is a permanent, outdoor, full-scale pavement testing laboratory located at the Federal Highway Administration's (FHWA) Turner-Fairbank Highway Research Center in McLean, Virginia. The purpose of this facility is to quantify the performance of test pavements trafficked under accelerated loading. The facility consists of several instrumented test pavements and the Accelerated Loading Facility (ALF) testing machine. Formal operation of the facility began in October 1986. This report summarizes the work performed during the first phase of research, October 1986 to April 1989. The report includes a discussion of the construction and instrumentation of the PTF test pavements. It describes the operation of the ALF testing machine, and the data collection procedures used at the PTF. The report also summarizes the environmental, and pavement response and performance data collected during the first phase of research. Finally, an analysis of the accelerated pavement testing data was conducted to assess the strengths and weaknesses of accelerated testing with the ALF machine
