Macadam Rakers play a crucial role in road construction by ensuring the even distribution and compaction of macadam, a type of aggregate used as a base layer for roads. Their primary responsibilities involve:

1. Preparing the Roadbed

Macadam Rakers begin by preparing the roadbed, which is the foundation of the road. They level, grade, and compact the soil to create a stable surface for the macadam.

They spread macadam aggregate evenly over the prepared roadbed, using specialized equipment or manual labor. They ensure the correct thickness and depth of the macadam layer as per specifications.

3. Raking and Leveling

Using rakes, they smooth and level the macadam surface to achieve the desired grade and slope. They carefully remove any excess material or debris.

4. Compacting Macadam

To achieve the required density and strength, Macadam Rakers compact the macadam using heavy rollers or vibratory plates. They operate this equipment skillfully to ensure uniform compaction throughout the layer.

5. Finishing and Clean-up

Upon completion, they finish the macadam surface by applying a sealant or dressing to enhance durability. They also clean up the work area, removing any tools or materials.
