StratoTest asphalt thickness gauge

The StratoTest 4100 is a highly developed, non-destructive road layer thickness measuring gauge to measure bituminous road layers or other electrically insulating road layers. Initially developed for measuring bituminous wearing courses, the StratoTest nowadays is mainly used for road inspection and cost settlement according to the German standard TPD StB 89. Due to its versatility, it can also be used for wall thickness measurement or thickness measurement of unreinforced concrete linings. Measurement with the StratoTest is unaffected by humidity or temperature of the layer material. Furthermore, even strong variations in the magnetic or electrical properties of the layer material or variations in the ambient temperature do not impair the measuring results.

The StratoTest 4100 is designed for on-site testing of pavement thickness. This most accurate electronic gauge provides immediate thickness readings of road layers during construction work. As a result, road layers can be paved more accurately and economically avoiding increased factor of safety for pavement thickness. At the same time, the risk of invoice deductions can be prevented when it comes to cost settlement.

The easy to operate StratoTest provides quick and accurate readings that are provided in correlation with their relevent measuring spots and stations without the need of extended set-up times. With real-time test reports being immediately at hand, the StratoTest proved to be the ideal gauge for road inspection.

During pavement works, reflector foils are installed under the road layers at pre-selected measuring spots for later inspection through the road constructions authorities. Mounted on a foldable dolly, the gauge fits perfectly into any car.

The core drill method of road surface testing is a destructive, time-consuming, costly and inaccurate procedure. The StratoTest has none of these drawbacks, combining completely non-destructive measurement with accurate and repeatable test results displayed within seconds. The newly developed gauge is based on 20 years experience particularly for experts in road construction. As with former models, the new gauge measures the thickness of all materials used in road construction.
