Edition 1.0, published in August 2018, was previously published as Guide to Pavement Technology Part 4K: Seals. This new edition of the Guide has been restructured and content updated to improve overall readability and usability, and incorporates sprayed seal design (Sections 5 and 6), which was previously published in a separate document.

The terminology used to describe sprayed seal treatment types has been updated, with some name substitutions and additions, and inclusion of different material usage based on the findings of recent Austroads studies (Section 3). New information for selecting sprayed seals is included (Section 4). Various updates to design parameters have been updated to reflect current practice (Section 6).
