AS/NZS 2891.13.1:2013 is a standard that provides guidelines for the sampling and testing of asphalt to determine its resilient modulus using the indirect tensile method. The purpose of this standard is to establish a consistent and reliable laboratory procedure for evaluating the performance and durability of asphalt materials.

The resilient modulus of asphalt refers to its ability to withstand repeated loading and recover its original shape after deformation. This property is important in assessing the structural integrity and long-term performance of pavements. The indirect tensile method involves subjecting cylindrical asphalt specimens to repeated loads under controlled conditions.

The standard specifies the detailed procedures for preparing the test specimens, applying the load, measuring the deformation, and calculating the resilient modulus. It provides guidance on the equipment, testing apparatus, and test conditions necessary to ensure accuracy and repeatability of the results. Compliance with this standard ensures that the resilient modulus values obtained are reliable and can be used for designing and evaluating asphalt pavements.
