CPD: Up to 20 Hours
Level of difficulty: Advanced

A spray seal design is a complex and technical process that requires a high level of competence and expertise to ensure a safe, durable, and effective outcome.

The selection of treatments involves different costs and risks in performance outcomes. Designers are required to use their own experience and judgment in the selection and detailed design of the surfacing.

Successful completion of the AfPA Sprayed Sealing Selection and Design course is recognised as the industry standard in order to be acknowledged as a competent spray seal designer.

The Queensland Department of Transport and Main Roads require Seal Designers to have successfully completed this course and be added to the Spray Seal Design Registry.

Course Benefits

This course helps you minimise the risk of seal failures, maximise value for money, and reduce liability by teaching you how to select and design sprayed seals that are tailored to traffic, pavement, and environmental conditions. You will learn a rational, reliable, and proven approach to designing effective spray seals.

Scope

The course covers the when, where, and how of using sprayed treatments. Participants will gain an in-depth understanding of the strengths and weaknesses of different sprayed treatments, including how to address various surface defects. The course also focuses on the application of the current Austroads seal design method for priming, primer sealing, and sealing. Real-world examples and interactive workshops will guide participants through practical design exercises.

Who should attend?

This course is intended for:

• Engineers
• Supervisors
• Consultants, and
• Technical officers who are responsible for specifying, selecting, reviewing, or designing sprayed treatments.

Outcomes

By the end of this course, participants should be able to:

• Identify and describe different types of sprayed treatments for new works and retreatments.
• Explain the functions of various sprayed treatments.
• Select appropriate sprayed treatments for both new works and retreatments.
• Design primes, primerseals, single/single seals, double/double seals, high-stress seals, extreme-stress seals, geotextile seals, and polymer-modified seals.
• Analyze how changes in design inputs affect seal performance.

Assessment

Assessment is a written assignment to be submitted and marked. Course attendance is a per-requisite of assessment. Only those who successfully complete the assignment will be listed as approved Seal Designers on the AfPA website (QLD only).
