The light-weight deflectometer (LWD) has seen increased use in quality control and quality assurance testing. Pavement applications include general assessment of unbound layer stiffness and controlling the quality of compacted aggregate and soil layers. TRB will host a webinar on Thursday, February 23, 2023 from 1:00 PM to 2:30 PM Eastern that will share test set up, data analysis, and limitations of the LWD device. Presenters will share two case studies of conventional and non-conventional uses of LWDs and discuss any potential issues to ensure proper data collection and analysis.
This webinar is a follow on to the TRB Webinar: Ensuring Construction Quality Assurance with Light-Weight Deflectometers held on September 30, 2021.
