The quality and performance of pavement markings have increased in recent years thanks to better paint and thermoplast and higher performing glass beads. New, marking types have also improved, in particular the performance during wet conditions at nighttime by allowing better run-off of water.
In parallel, costs of material have increased having made road owners interested in knowing the actual amount of paint or thermoplast applied. Measurement of the thickness of the markings is used for verification.
DELTA has recently launched a digital marking thickness gauge. The marking thickness gauge is able to measure the thickness of road markings up to +/- 12.7mm or 0.5in when dry after application.
The marking thickness gauge is simple to calibrate and use, making it a convenient instrument at hand for checking the thickness of a road marking, either when new markings have been applied or when having to decide on maintenance needs.
