What is BS EN 16659 - Multiple Stress Creep and Recovery Test (MSCRT) of bituminous binders about?
BS EN 16659 is the European standard on bitumen and bituminous binders used as a binding agent being strongly adhesive and resistant to damage from water and oil spills.
BS EN 16659 covers the determination of percent recovery and non-recoverable creep compliance of bitumen and bituminous binders by means of Multiple Stress Creep and Recovery (MSCR) testing.
The MSCR test is conducted using the Dynamic Shear Rheometer (DSR) in creep mode at a specified temperature.
The percent recovery at multiple stress levels is intended to determine the presence of elastic response and stress dependence of bituminous binders.
The non-recoverable creep compliance at multiple stress levels is intended as an indicator for the sensitivity to permanent deformation and stress dependence of bituminous binders.
Note: BS EN 16659 does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of BS EN 16659 to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
Who is BS EN 16659 - Multiple Stress Creep and Recovery Test (MSCRT) of bituminous binders for?
BS EN 16659 on bitumen and bituminous binders is useful for:
- Builders and architects
- Civil engineers
- Manufacturers of the rheometer devices
- Manufacturers of bitumen and bituminous products
- Manufacturers of binders and sealing materials
Why should you use BS EN 16659 - Multiple Stress Creep and Recovery Test (MSCRT) of bituminous binders?
A creep and recovery is the standard rheological test protocol whereby a bitumen specimen is subjected to a constant load for a fixed time period, then allowed to recover, at zero loads, for a fixed time period.
BS EN 16659 provides the laboratory apparatus for the MSCR test that includes Dynamic Shear Rheometer (DSR), moulds or sheet materials and oven.
Preparation of rheometers, set up and zero-gap setting are all set out in BS EN 16659 for test preparation and procedure.
Calculations and expressions of test results to determine the average percent recovery are outlined in BS EN 16659 along with precision limits.
Furthermore, BS EN 16659 guides you through the stress creep-recovery (MSCR) test, which is used to evaluate bituminous binders at high service temperatures, specifically the stress or loading resistance.
As a result, bituminous materials are utilised for building construction, roofing, waterproofing, and other applications that are extremely impermeable to water passage, assuring longevity and strength and preventing structure breaking.
