Project title: Collection of materials and performance data for Texas flexible pavements and overlays

Project 0-6658This five-year project was initiated to collect materials and pavement performance data on a minimum of 100highway test sections around the State of Texas, incorporating flexible pavements and overlays. Besides being used tocalibrate and validate mechanistic-empirical (M-E) design models, the data collected will also serve as an ongoingreference data source and/or diagnostic tool for TxDOT engineers and other transportation professionals. Towards thisgoal, this interim report provides a documentation of the comprehensive data analysis plans that were developed toanalyze the collected data. The data collection plans are documented elsewhere as Report 0-6658-P1.As documented here, the data analysis plans were designed to cover various key aspects, including thefollowing: (1) the tools and test methods used to measure/collect the data, (2) the type and format of the datameasured/collected, (3) the raw data reduction processes for each data type, (4) the software used to process andanalyze the measured/collected data, (5) the analytical methods and models used to analyze the measured/collecteddata, (6) the dimensional and/or quantitative units of the measured/computed parameters, and (7) the data reportingformat including how the data will be accessed and displayed from the MS Access Data Storage System (i.e., tables,graphs, bar charts, etc.). Specifically, the data to be analyzed included the following: (1) laboratory and field test dataincluding asphalt-binders, hot-mix asphalt (HMA) mixes, base, and subgrade soil materials; (2) traffic data; and(3) environmental and climatic data
