The quality and performance of pavement markings have increased in recent years thanks to better paint and thermoplastic materials and higher performing glass beads. In addition, new marking types have improved the performance during wet conditions at nighttime by allowing better run-off of water.
In parallel, cost of materials has increased having made road owners interested in knowing the actual amount of paint or thermoplastic applied. Measurement of the thickness of the markings is used for verification. The DELTA Marking Thickness Gauge is a portable robust instrument, which can provide quick and accurate thickness measurements in the field.
