The stabilometer was originally developed by the California Division of Highways to measure the combined effects of frequent traffic loads, repeated over a long period of time, on a given bituminous mix.

Test results are used to determine the maximum amount of bituminous binder which can be used without causing instability.

This application is developed around the accepted standard “Method For Determining The Resistance “R” Value Of Treated And Untreated Bases, Subbases and Basement Soils using the Hveem Stabilometer” typically used by Departments of Transportation and suppliers of road surfaces.

The stabilometer is a triaxial testing device used to determine the stability of bituminous paving mixtures, soils and other plastic or semi-plastic materials.

Tinius Olsen has modified a standard stabilometer device by adding a pressure transducer and position encoder. The test process is automated under Tinius Olsen’s Test Navigator software ensuring minimal operator input, performing all the test calculations and providing a traceable test report.
