Summary: Milling
asphalt for resurfacing
Cold planers, also known as milling machines or
asphalt grinders, are construction machines used to remove the surface layer of
asphalt or concrete pavement. This process is called cold planing or milling,
and it's a crucial step in road repair, resurfacing, and rehabilitation
projects.
Function: Cold planers use a rotating drum equipped with cutting teeth to grind away the existing pavement to a specified depth. This creates a level and textured surface for the new asphalt or concrete layer to bond to.
Mechanism: The rotating drum, powered by a powerful engine, chips
away at the pavement. The machine also includes systems to collect the milled
material (which can often be recycled) and control dust.
Applications: Cold planers are essential for:
* Removing damaged or
deteriorated asphalt or concrete.
* Leveling uneven pavement
surfaces.
* Creating a textured surface to
improve bonding with new pavement.
* Preparing surfaces for
overlays.
Benefits: Cold planing offers several advantages:
* It allows for precise removal
of only the damaged layers, preserving the underlying base.
* It creates a recycled asphalt
product.
* It improves the quality and longevity of the new pavement.
