Asphalt milling in South Africa
Cold planers (asphalt milling machines) cut up to a defined depth of old asphalt, producing reusable RAP (recycled asphalt pavement) and a prepared surface ready for new overlay. SA's road rehabilitation programme — from N-routes to provincial and municipal roads — runs a continuous demand for milling capacity.
Sizing by cutting width
0.5–1.0 m small cold planers — utility cuts, patches, tight urban work, manhole and trench preparation. 1.0–1.5 m medium — general road resurfacing, municipal contracts. 2.0–2.2 m large — highway mainline, high-productivity projects.
Brand landscape
Wirtgen (Germany) is the absolute global and SA market leader — the W series defines the category. Bomag, CAT and Roadtec are credible alternatives, particularly in the mid and large segments.
What to inspect on a used cold planer
Cutting drum condition — drum body, pick holders and pick wear pattern. Replacement drums are a major cost line. Conveyor system — belts, idlers, structural condition. Hydraulic system — leaks, cylinder rod condition. Tracks — pad condition, drive sprockets. Engine — service history, emissions condition (Tier compliance matters for newer machines). Operator station — vibration mounts, controls. A milling machine is a high-utilisation asset — service history and operator records are critical.
