Milling & Paving
Milling
This resurfacing method involves using a milling machine to remove the top layer of asphalt to a typical depth of 2 inches. The process grinds down the pavement with a rotating drum, collecting the old asphalt (millings) to be recycled. After milling, a new asphalt layer is laid, matching the removed thickness. Ideal for projects where the underlying base is still in good condition, milling is cost-effective for municipal, highway, and larger commercial projects. However, it doesn't address underlying issues such as poor base material or foundation failures.
Full Depth Reclamation (FDR)
FDR is a comprehensive pavement rehabilitation method that involves pulverizing the entire asphalt layer along with a portion of the underlying base. The mixed materials are then stabilized to form a new base course for new asphalt paving. This process is highly sustainable, minimizing material hauling and associated costs while addressing underlying base issues, effectively renewing the pavement's lifespan.
Choosing the Right Process
Understanding these two paving techniques and their benefits is crucial for effective pavement management. While milling offers a quick and less costly resurfacing option, FDR provides a more thorough solution for pavements with underlying issues. Consulting with a paving expert can guide you through the details of each method, offering tailored recommendations and a management plan to ensure long-lasting pavement performance.
