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. It is important to use binders which have a sufficient level of cohesion according to the level of traffic to be supported.

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.

Key Features

• Automatic security safety catch avoiding  pendulum to crash after test impact
• Incremental distance sensor in combination with a digital display accurate to 0,1°
• 36 cube and cube holder combinations, which allows an economic production of test samples
• Efficient safety system in compliance with EC - machinery directive 98/37/EC which allows comfortable handling with maximum operational reliability
• Module with built-in RS 232-port (allows the metering of test value via computer, retrofittable by user)
• Software available for full automation of test
  

Key Uses

• Bitumen
• Bitumen emulsions
• Flux bitumen

Standards

• EN 13588
• EN 13808
• EN 15322

Software

• 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 up-loaded 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 your data.
• Retrofittable on previously supplied pendulums
