The Dipstick® from The Face® Companies is the gold standard for the flatness/levelness measurement of pavements, bridge decks, airport runways, taxiways, etc.

The Dipstick is used and specified in 66 countries by clients including the World Bank and the World Road Association (PIARC).

A World Bank Standard Class 1 device, the Dipstick measures International Roughness Index (IRI), Half-Car IRI, ASTM E1926-08, and many other roughness indices. And Dipstick instantly calculates IRI and instantly produces graphs on-site.

The Dipstick Road Profiler is also specified by the United States Federal Highway Administration (FHWA).

The American Association of State Highway and Transportation Officials (AASHTO) has established its Standard R 41 [most recently published as R 41-05 (2010)] to, “… collect precision profile data utilizing the Face Technologies Dipstick.” AASHTO has found that the Dipstick, “measures profiles (relative elevation differences) at a rate and accuracy greater than traditional rod and level surveys.”

The Dipstick is recognized in road industry studies as the ideal device for establishing reference road roughness data for calibrating high speed profilometers and response type road roughness measuring systems.

Dipstick Road Profiler Operation

The operator simply “walks” the Dipstick along a survey line alternately pivoting the instrument about each leg.

Two digital displays show the elevation difference between the Dipstick’s two support legs.

Audible and visual signals alert the operator when each elevation difference reading is measured and automatically recorded.
