TDR 시스템을 활용한 철도노반 다짐관리

초록

Soil water content and dry density are important factor to manage compaction of the railroad and road. The modern compaction control is used for measuring water content and dry density by using the TDR(Time domain Reflectometry). However, some problems are able to occur when TDR system is used. This study was conducted to minimize problems. In this study, flat-type probe is developed. Also, to verify the developed TDR system, TDR tests were examined by comparison of the measured values by TDR and the real value. Based on the test results, it has been confirmed that accuracy of the developed TDR system is similar with previous TDR system.
