Live Online - Road Surfacings - Sprayed Seals
This practical course by live webinar is presented in two half day packages of two sessions each, with an optional workshop session on day 3. The courses focus is on sealed roads in rural environments and is ideal for project/asset managers of roads, senior supervisors, engineers and engineering technologists, working for federal, state, or local agencies, consultants and contractors.
Presented live, the course will navigate through the Austroads Guide (2018) for selection and design of sprayed seals and presents it in a logically flowing manner. It starts with a basic-level introduction to functions of a pavement and functions of a 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, single/single, double/double, low volume roads, and heavy vehicle roads. Tutorials are given on each of these topics, together with their worked examples. The differences for aerodrome runway seal designs will also be briefly introduced.
