CEN Technical Committee TC 227 has been formed to produce European Standards for materials for roads, airfields, and other paved areas. Penetration test, Softening point test and Viscosity test were. The types of bitumen covered by this Standard include penetration grade, oxidised, hard, and cutback bitumens. A sample of test reports issued by the bitumen suppliers were also taken in to consideration.

In the UK, bitumens are manufactured to BS 3690: Parts 1 to 3, of which Part 1 covers bitumen for road purposes. The Fraass breaking-point test (IP 80, EN 12593) can be used to describe the behaviour of bitumens at very low temperatures, down to -38 degrees C. Importance of the following tests a-penetration test b-ductility test, C-softening point test, d-viscosity test, e-rolling thin film oven test, f. Kinematic and dynamic measurement can be measured by instruments including capillary, cup, and high-temperature rotational viscometers. The viscosity of a bitumen is fundamental, as it determines how the material will behave at a given temperature or over a given temperature range. The penetration test (IP 49, ASTM D 5, BS 2000: Part 49, EN 1426) and the softening point test (IP 58, ASTM D 36, BS 2000: Part 58, EN 1427) measure the consistency of a penetration or oxidised bitumen. Pharmaceutical Paints Adhesives SwRI uses a variety of test methods in our laboratory. Most of the methods quote limits for assessing the acceptability of test results. This paper presents standard specification tests for bitumens, which have been developed by the Institute of Petroleum (IP), the American Society for Testing Materials (ASTM), the British Standards Institute (BSI), and the CEN in Europe.
