  • Publication no: ATM-121-26
  • Published: 19 February 2026
  • Edition: 7.1

This test method sets out the procedures for the determination of consistency, consistency 6%, stiffness and elastic recovery of polymer modified binders (ARRB elastometer), under specific conditions of deformation, using the elastometer developed by ARRB.

This test method can also be downloaded as a Word document.
