| 摘要： | Deflection basin measurements for the purpose of stuctural capacity evaluation are a key component of the Strategic Highway Research Program's (SHRP) Long Term Pavement Performance (LTPP) monitoring Program (LTPP). Because a standard method for evaluating the structural capacity of flexible pavements from deflection data does not presently exist, a SHRP program is developing a layer moduli backcalculation procedure for use in the initial anlaysis of the SHRP deflection data. This procedure covers not only the software but also the rules and guidelines used in applying the program. This report focuses on the standard procedure used to ensure that the LTPP deflection data analysis is as consistent, productive, and straightforward as possible. The procedure consists of a rigorous set of application rules used to generate data files for direct input into the backcalculation program - modeling of pavement structure and layer moduli ranges or initial module. Additional rules address the subsequent evaluation of the backcalculation results. |
