AS/NZS 2341.10:1994 is a standard that specifies a method for testing bitumen and related roadmaking products, specifically the determination of the effect of heat and air on a moving film of bitumen. This test is known as the Rolling Thin Film Oven (RTFO) Test.

The purpose of the test is to simulate the conditions that bitumen experiences when it is used in the production of hot-mixed asphalt. The standard outlines a procedure for measuring the flow properties of the bitumen before and after it undergoes the specified treatment.

The test involves subjecting a thin film of bitumen to elevated temperatures and air flow for a specific duration. This process aims to mimic the heating and oxidation effects that bitumen would undergo in an asphalt mixing plant. The flow properties, such as penetration and softening point, are then measured before and after the treatment to evaluate any changes that occur due to the heat and air exposure.

The results of this test provide valuable information about the durability and performance of bitumen when used in road construction. By determining the effects of heat and air on bitumen, engineers and industry professionals can make informed decisions regarding the selection and use of bitumen in asphalt mixtures, ensuring the longevity and quality of road surfaces.
