| 摘要： | Time domain reflectometry (TDR) has become one of the most reliable methods for measuring in-situ soil moisture content. TDR sensors developed by the Federal Highway Administration (FHWA) are being used in the Long-Term Pavement Performance (LTPP) Seasonal Monitoring Program (SMP) to monitor the in-situ moisture content at selected LTPP sites. The main goal of the study reported here was to develop procedures to produce good estimates of in-situ gravimetric moisture content. All the TDR traces in the LTPP database were processed using the approach described in this report. |
