• Abstract:
  To complete the objectives, AASHTO T 366-09 results will be compared to ASHTO TP 60-00 results. The results will then be used as input values for the MEPDG and the results evaluated. ; Major changes between AASHTO TP 60-00 and AASHTO T 336-09 will be reviewed and the implication of the changes will be investigated. Since the commercial automated divide (HM-251) is used to measure CTE value, the software that controls the testing procedure should be upgraded to account for the difference in CTE values for the calibration specimen. ; After the software is upgraded, the correct CTE of the specimen used for the LTRC project 07-02C will be measured based on AASHTO T 336-09. By comparing the CTE value measured by AASHTO TP 60-00 and AASHTO T 336-09, the correction factors will be calculated to produce correct CTE values for duplicated specimen without further measurement. ; This project will greatly assist the Department in implementation of the Mechanistic-Empirical Pavement Design Guide. The updated CTE values will allow LADOTD design engineers to better predict long term portland cement concrete pavement performance.
