Cooper-Vialit Cohesion Pendulum

Vialit Cohesion Pendulum by Cooper CRT-VCP is a testing device to analyse the cohesion of bitumen in road construction. The cohesion is one of the measures of the performance of a bituminous binder. Cohesion has originally been developed for surface dressing; however, it can be used for any type of binder (pure, modified or fluxed) which is to be used in different types of road applications. Knowledge of cohesion enables the choice of binder type for given traffic and site conditions.The European Standards EN 13808 and EN 15322 demand this test according to EN 13588 as a basis for the CE marking of all polymer-modified binders for the intended use of surface treatment.

  • User friendly, intuitive and reliable windows software developed with National Instruments LabVIEW
  • Results are taken for the binder under test, across the pre-determined temperature range and displayed in real time. Results are stored in a single Microsoft Excel compatible csv file
  • Previously stored data can be uploaded to allow changes/additions to the tests already carried out on the binder under test
  • On–screen chart shows the cohesion vs. temperature curve which updates in real time as new measurements are taken
  • User level access ensures calibration and other important setup parameters are secure
  • Software performs BS EN 13588-2008 BS 2000-522-2008
  • Translation of the software is available into most languages
  • The operator is guided through performing a test using the CRT-VCP
  • Auto recognition of connection between PC and CRT-VCP
  • File corruption detection to ensure the integrity of data
  • Retrofittable on previously supplied pendulums
