• Abstract:
  Comprehensive and reliable databases are essential for the development, validation, and calibration of any pavement ; design and rehabilitation system. These databases should include material properties, pavement structural ; characteristics, highway traffic characteristics, environmental conditions, and performance data. In general, ; performance data consists of the development of rutting, roughness, and cracking. ; It is true that these databases are currently available in Texas; however, they were originally designed and are ; currently being maintained with specific objectives in mind, which are not necessarily their potential uses for pavement ; design. Specifically, some of these databases have been designed for network level applications, not compatible with ; the calibration of data intensive performance models such as those typical of mechanistic-empirical design systems. ; The goal of this research project is the development of the Texas Flexible Pavement Database. In order to achieve ; this goal, a plan for the development of a sustainable database was conceived, followed by the development of interim ; database structures in MS Access for uploading the required data and for data sharing. The initial population of the ; database has been initiated with the objective of performing local calibration. This integrated database approach has ; been designed as a project-level application with the purpose of developing, validating and calibrating empirical or ; mechanistic flexible pavement design models. It will interact with and complement the Pavement Management ; Information System (PMIS) and other existing databases such as the Design and Construction Information System ; (DCIS). This report summarizes the research progress during the first year of the research project.
