ahis report summarizes the development of the Long-Term Pavement Performance (LTPP) program's climatic database, including the identification and sources of data, selection and verification of weather stations, actual data retrieval from available sources, and data quality assurance. The paper also discusses future activities such as updates and expansion of the database, and the collection of ground-truth data. The LTPP climatic data base is intended to provide the weather and climatic information needed to characterize the environment in which each LTPP test section has existed from the time of construction through the LTPP monitoring period. |
