Abstract
The procedures for obtaining Temperature Conversion Factor (TCF) are described. This factor accounts for the pavement temperature variation during full-scale truck trafficking. This variation results from changes in air temperature and the distribution of temperature with depth in the pavement structure. Repeated load triaxial tests at multiple temperatures were conducted to consi der temperature effects on an asphalt mixture in terms of permanent deformation. The TCF was calculated using the results of repeat ed load triaxial tests and layered strain procedures based on field temperature distribution with depth. The TCF was applied to convert ESALs at the field temperatures to ESALS at the standard temperature, which can be used in temperature controlled laboratory accelerated pavement tests (APT) or material property tests. The TCF provided a simple, convenient way to convert traffic loading at various temperatures to its equivalent at a standard temperature
