BS EN 16659:2015涵盖了回收率和不可回收蠕变的测定 通过多重应力蠕变和恢复（MSCR）对沥青和沥青粘合剂的符合性 测试。使用动态剪切流变仪（DSR）在蠕变模式下以规定的速度进行MSCR试验 温度多个应力水平下的恢复百分比旨在确定是否存在弹性 沥青粘合剂的响应和应力依赖性。在多个应力水平下的不可恢复蠕变柔度旨在作为 沥青粘合剂对永久变形和应力依赖性的敏感性。本欧洲标准并非旨在解决与以下各项相关的所有安全问题（如有） 它的用途。本欧洲标准的使用者有责任建立适当的安全和环境标准 并在使用前确定监管限制的适用性。交叉引用:EN 58EN 12594EN 12597EN 14770ISO 5725-2:1994购买本文件时可获得的所有现行修改件均包含在购买本文件中。

BS EN 16659:2015 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.This European Standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this European Standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.Cross References:EN 58EN 12594EN 12597EN 14770ISO 5725-2:1994All current amendments available at time of purchase are included with the purchase of this document.
