Temperature Correction Method for Asphalt Pavement Dynamic Deflection
The in-situ falling weight deflectometer (FWD) tests were conducted to develop a temperature correction method for asphalt pavement dynamic deflection. Results indicate that different values of temperature correction coefficient K were predicted by asphalt pavement static resilient deflection under JTG D50 and JTG E60 specifications, particularly at low temperatures. For asphalt pavement dynamic deflection, the JTG D50 method presented low precision, where as the JTG E60 method lacked an analytical formulation and displayed a limited valid layer thickness. A mathematical expression was developed for the temperature correction coefficient K on the basis of the falling weight deflectometer test results. The measured K values were consistent with those predicted using the proposed expression. In addition, the parameters in the expression were clearly defined, thereby providing basis for further study.
