Cover of Characterisation of Flexural Stiffness and Fatigue Performance of Bituminous Mixes
Characterisation of Flexural Stiffness and Fatigue Performance of Bituminous Mixes
  • Publication no: AGPT-T274-16
  • Published: 21 January 2016

The test method specifies procedures for the characterisation of the stiffness and fatigue behaviour of bituminous mixtures using a four-point bending test configuration.

This test method should be read in conjunction with the European Standards EN 12697-24:2012, Bituminous mixtures – Test methods for hot mix asphalt – Part 24: resistance to fatigue and EN 12697-26:2012, Bituminous mixtures – Test methods for hot mix asphalt – Part 26: stiffness, published by the European Committee for Standardization. This Austroads method provides instructions on conducting tests in accordance with these European Standards, while complying with Austroads specimen preparation methodology and test conditions.
