Road Surfacings - Sprayed Seals
Delivered via Zoom
This practical course by live webinar is presented in two half day packages of two sessions each, with an optional workshop session. 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.

Dr Kym Neaylon - Principal Engineering Advisor - Pavement Surfacings (CPEE)
Kym's early civil engineering career was a practical basis in open cut mining, local government engineering, state government, road
construction and contract superintending before specialising in bituminous pavement surfacings for the last 30 years. Coming from a
practical background, his PhD dissertation was the first in Australia in the field of sprayed sealing.
He has consulted in bituminous surfacings for most state road jurisdictions in Australia, and in New Zealand, Ethiopia and Fiji. For six
years whilst at the Australian Road Research Board he project-led Austroads research projects in areas of chip sealing, bituminous
binders, and skid resistance. Prior to that for 17 years he was the Surfacings Engineer with the South Australian Government. He is
currently the chairman of the Australian Standards committee on bitumen and related products for road making.
Who should attend?
- State road agency and local government engineers and managers with responsibilities in the provision, approval, design, construction or maintenance of concrete roads & pavements. This to also include project managers and senior supervisors.
- Consulting engineers with involvement in road and/or pavement projects.
- Road & Pavement construction contractors, engineers, project managers and supervisors.
- Local Government engineers, project managers and senior supervisors.
- Technical operatives and Engineering graduates and “cadets” looking for specialist knowledge for career development.
