This course is both a refresher and more expansive insight into sprayed sealing principles and application that will benefit project managers, contract managers, asset managers and technical specialists in State Road Authorities and Local Councils. It will also benefit technical and operational staff who work for road construction contractors.
Unit 1: Fundamentals of Sprayed Sealing provides an overview of what sprayed seals are and why they make up the majority of the Australian sealed road network. The types of sprayed seals and their component materials are discussed, alongside methods to assure appropriate selection of sprayed seal treatments for the variety of purposes they may can be applied to. An overview of the design procedure and construction methods are also described.
Unit 2: Intermediate Selection and Design of Sprayed Seals includes a more in-depth focus on the seal design process and worked examples of these. Participants will gain a basic competency in designing single / single and double / double treatments.
