| 摘要： | Worldwide, pavement design and analysis is moving toward deflection or mechanistic-empirical procedures. A difficulty with these procedures is that they require some type of adjustment factor to adjust the measured deflections or the layer elastic moduli used in the procedure because of the time of day and year (season) when field measurements are taken, and; the effects of climate related material variations on pavement performance. The basic objectives of this study were to examine seasonal adjustment factors for deflections and layer moduli and to provide guidelines for selecting seasonal adjustment factors that provide a more realistic pavement design. Three sets of deflection basin measurements (Japan, WSDOT, and U.S. Forest Service) were used to estimate seasonal moduli. The EVERCALC Version 3.3 backcalculation program was used to estimate these moduli. Based on such results, along with those in the literature, as set of moduli ratios were developed. Additionally, recommendations on deflection ratios were made. |
