| 摘要： | The objective of this research program is to analyze the performance of flexible pavements in North Carolina utilizing full-scale pavement sections. The specific objectives include: (1) collect data pertaining to material properties for use in mechanistic design methods; (2) Develop a mechanistic pavement performance predictive model; (3) Compare field performance of pavements of known design with predicted performance; and (4) Evaluate the effect and different types and thicknesses of pavement layers on pavement distress and performance. This interim report contains the details of the instrumentation, initial analysis of the field data collected through periodic field testing, and preliminary trends and observations of performance of the pavement sections. |
