CORRELATION ANALYSIS OF MEASUREMENT RESULTS USING THE LIGHT WEIGHT DEFLECTOMETER (LWD) TOOL AGAINST THE FALLING WEIGHT DEFLECTOMETER (FWD) TOOL

Currently in Indonesia, a tool that can measure flexible pavement characteristics on roads with low traffic volume has been developed, namely the Light Weight Deflectometer. This tool is able to read deflections without damaging the existing pavement or non-destructive tests, has good mobility a...

From the research conducted, it was found that the correlation of D300, D600, BLI, and MLI between LWD and FWD data had a good correlation level, but from the results of the overlay needs analysis it was found that the overlay requirement from the LWD deflection data was smaller than the overlay requirement from the FWD data. This proves that LWD utilization is used to detect pavement damage for maintenance purposes, not for deflection measurements which are then used for overlay design. text
