Whether you require micro milling for minor surface irregularities or full-depth removal for complete resurfacing, our comprehensive range of milling services has you covered.
Understanding Asphalt Road Milling
Asphalt milling, also known as cold planing or profiling, is a process that involves removing the top layer of an existing asphalt surface. This technique utilises specialised milling machines equipped with a rotating milling drum studded with cutting teeth. As the drum rotates, it grinds and removes the old asphalt, leaving behind a textured surface ready for resurfacing or repair.
What is Cold Milling?
While cold and asphalt milling are often used interchangeably, there is a subtle difference. Cold milling refers specifically to the process of removing the asphalt surface at ambient or cooler temperatures without the application of heat. This method is preferable as it minimises the risk of damaging the underlying pavement structure.
Importance of Milling in Pavement Projects
Surface Preparation
Milling allows for removing existing surface irregularities, cracks, and other defects, creating a uniform base for new asphalt or concrete overlays.
Drainage Improvement
Milling can improve drainage and prevent water accumulation on the road surface by removing the top layer of asphalt, reducing the risk of potholes and other water-related damage.
Cost-Effective Resurfacing
Rather than completely reconstructing the pavement, milling enables the reuse of the underlying layers, making resurfacing projects more cost-effective.
Recycling and Sustainability
The milled asphalt (known as reclaimed asphalt pavement or RAP) can be recycled and reused in new asphalt mixes, promoting sustainability and reducing waste.

Types of Asphalt Milling
Micro Milling
Also known as surface or thin milling, this type of milling involves removing a thin layer of asphalt, typically no more than 1 inch deep. This method is often used for minor surface repairs, such as addressing surface bumps, improving friction, or creating rumble strips. Micromilling is a suitable solution for maintaining and extending the lifespan of asphalt surfaces.
Fine Milling
Fine or partial depth milling involves removing a thicker asphalt layer, usually between 1 to 2 inches deep. This technique is suitable for addressing more significant surface defects, such as rutting or moderate cracking. Fine milling prepares the existing surface for an asphalt overlay or resurfacing, ensuring a smooth and stable base for the new pavement.
Full Depth Removal
As the name suggests, this milling involves completely removing the existing pavement to the base or sub-base layer. This method is typically employed when the asphalt surface is severely damaged, or the entire pavement structure must be reconstructed. This process is often followed by installing a new asphalt or concrete surface.
