Development of a Flexible Pavements Database, Project Summary
Flexible pavement databases have been used and served well in Texas since 1972. The first database consisted of 350 pavement sections, which were selected following a stratified random sampling approach. The original intent of developing this database was to come up with the performance equations and pavement condition prediction capabilities which were later incorporated into the Flexible Pavement System (FPS) software for flexible pavement design. With the advent of mechanistically-based pavement design approaches, popularity of the Falling Weight Defl ectometer (FWD) and back calculation techniques, the existing database failed to meet the challenges in terms of handling huge data sets that these procedures needed. To address these issues, a project entitled 'Preserving the Texas Pavement Database' was initiated. The motive behind this project was to preserve, improve, and update the existing database. Once this effort concluded, a period followed during which the data was not updated. In 2001, another project was initiated with an objective of populating the Flexible Pavement Database experimental cells with missing data. Unfortunately, by 2006, the data that existed was too obsolete to be used for the calibration and validation of data intensive mechanistic-empirical pavement design models. Hence, research project 0-5513 was initiated from ground zero with the goal of developing a web-based database, collecting and populating the database with the objective of validating and calibrating pavement performance models.
