Part 1: The primary purpose is to assist in the efficient management of unsealed rural roads. As well as addressing the fundamentals, advice is provided on design issues, improving material properties, construction and operational aspects.
Part 2: Navigates through the Austroads guide to selection and design of sprayed seals (2018) and presents it in a logically flowing manner. The course commences with a basic-level introduction to functions of a pavement and functions of a pavement surfacing and treatment selection. The focus is then on sprayed sealing, starting with fundamental seal design theory, followed by an explanation of the Austroads design methods for primes and initial seals (primerseals), single/single, double/double, low volume roads, and heavy vehicle roads. Time is devoted to tutorials on each of these topics. The differences for airport runway seal designs will also be introduced briefly. The course finishes with case studies on actual problems, and practical solutions.
