AS 2891.12.1:1995 PDF Download

The AS 2891.12.1:1995 standard provides a procedure for measuring the accumulated axial deformation response of asphalt mixtures commonly employed in road pavements. The standard details the method for conducting the test under standard conditions, and it can be applied to both cores extracted from existing roadways and laboratory-compacted specimens.

The purpose of this standard is to determine the permanent compressive strain characteristics of asphalt mixtures, particularly their dynamic creep behavior. By subjecting the specimens to axial deformation, it enables assessing the material's ability to resist deformation under sustained loads over an extended period. This test can help evaluate the performance and suitability of asphalt mixtures for use in road construction, considering factors such as long-term stability and deformation resistance.
