AS 2341.12:2020 PDF Download

AS 2341.12:2020 standard sets out the guidelines for determining the penetration of bituminous materials used in road construction. The purpose of this test method is to establish a standardized procedure for measuring the depth to which a standardized needle penetrates a sample of bitumen or related roadmaking product under specific conditions.

The standard specifies that it is applicable to bituminous materials with penetrations equal to or less than 200 (0.1 mm). This means that it covers a wide range of bitumen types commonly used in road construction, including both hard and soft bitumens. The primary objective of this test is to determine the consistency and stiffness of the bitumen material, which is crucial for assessing its suitability for various road applications.

The AS 2341.12:2020 standard provides detailed instructions on the equipment, sample preparation, testing conditions, and calculations required to determine the penetration value accurately. It ensures that the test results obtained from different laboratories are consistent and comparable. Compliance with this standard enables reliable and standardized characterization of bitumen and related roadmaking products, facilitating better quality control in road construction projects.
