How to prepare for Street Works operative assessment

Core concepts
Concept 1
Cold-lay materials have specification-defined uses, limitations and interim or permanent status.
Exam cue: Check the current national code and any product approval before use.
Concept 2
Material must be within shelf-life, stored correctly and workable for the weather and layer.
Exam cue: Inspect packaging, batch, storage history and material condition.
Concept 3

Exam cue: Prepare edges and remove loose or contaminated material.
