Slab Construction, Joints and Reinforcement
Identify slab type and condition and prepare sub-base, formwork, dowels, reinforcement and joints to design.
How to prepare for Street Works operative assessment
Connect technical knowledge to observable performance: check the jurisdiction and plan, select and inspect resources, carry out each stage safely, verify the result and stop when reality departs from the applicable code.
Core concepts
Concept 1
Rigid and composite roads may contain slab joints, dowels, reinforcement and overlays that require controlled exposure.
Exam cue: Locate and identify joints and reinforcement before breaking out.
Concept 2
The reinstatement design sets slab dimensions, concrete class, sub-base, joint and reinforcement requirements.
Exam cue: Check dowel alignment, debonding, cover and mesh support against the design.
Concept 3
Formwork, existing slab faces and support must be stable, clean and correctly positioned before concrete placement.
Exam cue: Verify dimensions, level and access before the pour starts.
Risk pitfalls and guardrails
Cutting through reinforcement without approved instruction.
Guardrail: Do not use a certificate, generic course note or familiar past site as a substitute for current plans, code, permission and physical verification.
Placing mesh directly on the sub-base.
Guardrail: Do not use a certificate, generic course note or familiar past site as a substitute for current plans, code, permission and physical verification.
Using existing cracked concrete as unsupported formwork.
Guardrail: Do not use a certificate, generic course note or familiar past site as a substitute for current plans, code, permission and physical verification.
