PD 6692:2018 PDF Download

PD 6692:2018 is a published document that provides guidance on the use of the BS EN 12697 standard. It is specifically focused on the UK market and local environmental conditions. The document is intended for various stakeholders involved in asphalt manufacturing and testing, including asphalt manufacturers, highway authorities, contractors, consultant engineers, equipment manufacturers, private infrastructure owners, and more.

The purpose of the document is to guide users on how to utilize each test method outlined in BS EN 12697 to ensure that the tests are relevant to the UK market, such as testing of constituent materials that are still in transit. The tests are categorized into five groups, which include methods required for testing constituent materials, methods called up in standard specifications for different types of asphalt, methods specific to certain standard specifications, test procedures to support specific test methods, and test methods and procedures not called up in asphalt standards.

The document also highlights changes from the previous edition, which was published in 2006. These changes include revisions and withdrawals of several test methods, as well as the introduction of new test procedures that do not have equivalent British Standards. Specific changes are related to crack propagation, tensile stiffness, low temperature cracking, ash content, interlayer bonding, friction after polishing, and scuffing.
