§ 02 — Sequence

Eight steps, in order.

The kerb plinth is poured first — its sharp ink-black edge acts as the side form for the Aggregate Base Course. From that single decision, the rest of the sequence resolves cleanly.

Concrete Pavement

Base slab build-up — kerb plinth, ABC, 20 MPa pavement

The reference build-up for the entire validation track footprint. The 200 mm 28 MPa kerb plinth is poured first to act as a hard edge form for the 150 mm Aggregate Base Course, which is then compacted with hand-held equipment along the edges. The 180 mm 20 MPa pavement slab is poured against the inner kerb face and finished flush with the top of kerb (T.O.K).

Key dimensions

Kerb plinth thickness: 200 mm
Pavement thickness: 180 mm
ABC thickness: 150 mm
Joint width: 20 mm
