LTPP Computed Parameter: Frost Penetration
| 项目名称： | LTPP Computed Parameter: Frost Penetration |
| 摘要： | The objective of this research project is to monitor the freeze penetration in base, subbase, and subgrade of pavement, LTPP instrumented selected test sections in the Seasonal Monitoring Program (SMP) with subsurface electrical resistivity probes and temperature probes. In 1997 the first SMP data were extracted from the LTPP Pavement Performance Database (PPDB) and interpretation was performed to identify locations of subsurface frost in unbound materials. [FHWA-RD-99-088] For this effort, an interactive program, FROST, was developed to aid in this interpretation. With the completion of monitoring measurements on the SMP sections in October 2004, there is a need to complete the interpretation of measurements not previously interpreted and add the results of these interpretations to the LTPP Pavement Performance Database. |
