The original scope of TxDOT Research Project 0-6275 included continuing the development of the Texas Flexible Pavement database (TFPD) developed as part of Research Project 0-5513. The objective of 0-5513 was to deliver a database capable of hosting the data necessary for new pavement design models that would result in more reliable and economical pavement design. The objective of 0-6275 was to continue the data collection and data population of the flexible pavement databases and to calibrate the models (transfer functions) used in the new MEPDG as well as TxDOTs mechanistic design checks. In addition, this new project was to review the development conducted in 0-5513 to evaluate whether the database created covered the inference space of pavements in Texas and to make the necessary additions and changes. Therefore, the efforts of 0-6275 were primarily twofold. |
