Sports Labs Hosts Largest LWD Correlation

Sports Labs hosted the world's largest gathering of Light Weight Deflectometer (LWD) devices at its headquarters and laboratory based in Scotland. A total of 33 devices and more than 40 companies from a broad spectrum of the industry came together for correlation on 11 June. The objective was to test and assess the reproducibility of results generated by the LWDs used on specially-prepared sub-base materials. Four different manufacturers were represented at the day-long trials which involved both laboratory and field testing. It's essential that devices are calibrated and that all output is within acceptable tolerances because the final results carry an important bearing on the regulation and standards overseeing monitoring base construction. Representatives from Highways England, Transport Scotland, Aecom, WSP supported the event together with FIFA / World Rugby and UKAS.
