Grasping the concept of asphalt milling cost is essential for anyone tasked with roadway maintenance or property management. Asphalt milling, a vital but often undervalued pavement preservation technique, efficiently removes just the deteriorated layer of asphalt, preserving the underlying structure.
This method is not only cost-effective but also crucial for preparing the base for a smooth new overlay. In this blog, we will detail the pricing factors of asphalt milling and highlight its long-term benefits for pavement upkeep. Whether you’re responsible for maintaining commercial lots, residential roads, or municipal highways, understanding the economic advantages of professional asphalt resurfacing by FLA1 Paving can result in significant maintenance savings and enhanced pavement longevity.
Asphalt milling, also known as cold planing, is a pavement maintenance process that involves removing the top layer of asphalt from a roadway, parking lot, or other paved surface. This technique is employed when the surface has deteriorated or has become significantly uneven, but the underlying base layer is still stable and intact.
Here’s how the process works:
Machinery Used: Asphalt milling is performed using a milling machine, which is equipped with a large rotating drum that removes and grinds the surface of the asphalt. The drum contains sharp metal teeth that cut into the pavement, efficiently scraping off the top layer.
Depth of Milling: The depth of milling can vary depending on the condition of the pavement or the specific project needs. Milling can be just superficial, removing only the top layer of asphalt to make way for a new top layer, or it can be deep, removing the full depth of the asphalt pavement down to the base layer.
Recycling the Old Asphalt: One of the significant benefits of asphalt milling is that the milled asphalt can often be recycled and reused in new paving projects. This not only makes the process economical but also environmentally friendly. The milled asphalt is typically taken to a processing facility where it is screened and sized. It can then be incorporated into new asphalt mixtures or used as a sub-base material.
Preparation for Resurfacing: After milling, the stripped surface is usually cleaned and prepared for the application of new asphalt. Milling provides a rough surface which enhances the adhesion between the old base and the new asphalt layer.
Advantages: The main advantages of asphalt milling include cost efficiency, speed of the project, and minimal disruption to traffic. It also provides the opportunity to correct underlying surface irregularities and drainage issues.
Asphalt milling is a preferred method for repairing and maintaining asphalt surfaces because it is faster, less disruptive, and more cost-effective than full pavement replacement. It is widely used not only to repair aging roads but also to adjust pavement height and improve drainage.
Breaking down the costs associated with asphalt milling is essential for understanding the overall value of this paving process. The total expense can vary widely depending on several factors that impact both the initial and long-term investment. Here's a detailed look at the key components that determine asphalt milling costs:
