ASTM D1370/D1370M is the ASTM standard for the Standard Test Method for Contact Compatibility Between Asphaltic Materials (Oliensis Test). It is used to help evaluate how asphaltic materials behave when placed in contact, which can be important for material selection, product comparison, and quality control. For buyers and technical teams, this standard supports more consistent testing and better confidence in compatibility-related decisions for asphalt-based materials.

Overview of ASTM D1370/D1370M

This standard provides a test method focused on contact compatibility between asphaltic materials, often referred to as the Oliensis Test. In practical terms, ASTM D1370/D1370M helps define a repeatable approach for assessing whether two asphaltic materials are suitable for contact or combined use. As an ASTM standard, it serves as a technical reference for laboratories, inspectors, and purchasers who need a common method for evaluating material behavior under a defined test procedure.

Common use cases of ASTM D1370/D1370M

ASTM D1370/D1370M is commonly used in testing programs involving asphaltic materials where contact performance matters. It may be applied during incoming material evaluation, formulation review, or product verification when compatibility between asphalt-based products needs to be checked. The standard is also relevant in quality control workflows for suppliers, laboratories, and engineering teams that compare materials under the same test conditions and want a recognized method for reporting results.

Benefits of using ASTM D1370/D1370M

Using ASTM D1370/D1370M can improve consistency in testing and reduce uncertainty when assessing contact compatibility. It gives procurement and technical teams a recognized ASTM reference for product evaluation, which may support clearer specifications and more reliable comparisons across suppliers or batches. For organizations focused on quality control, the standard can help strengthen documentation, support compliance efforts, and reduce the risk of using incompatible asphaltic materials in service.
