Although asphalt pavement is extremely durable, in time, all pavements will need resurfacing. Since merely installing new asphalt over existing pavement is rarely an option, the old pavement must be removed first. The traditional method is a complete removal and haul-off of the existing pavement. However, in many cases, asphalt milling or asphalt reclamation is the better option. At APM, although we can provide full removal and replacement, during the more than 35 years we have been in business, we have found that milling or reclamation is often superior for removing existing pavements.
MILLING AND RECLAMATION – THE DIFFERENCES
WHAT IS ASPHALT MILLING?
Asphalt milling involves the use of a milling machine to remove pavement to a controlled depth. The depth can be very precisely controlled so that only the exact amount of pavement is removed. The asphalt that is removed by milling can be taken to the processing plant for recycling.
WHEN WOULD WE RECOMMEND MILLING?
Asphalt milling can be used for a variety of purposes, including full-depth removal. However, there are certain situations in which we would be more likely to recommend milling.
• Refining pavement edges for an asphalt overlay
• When the removal must be extremely precise, such as limiting removal to just the surface layer
• To adjust the pavement’s slope or thickness
• To correct drainage issues
• To smooth transitions between connecting pavements
WHAT IS ASPHALT RECLAMATION?
Asphalt reclamation, also called rubbilizing, is commonly used as a cost-effective method of removing asphalt to its full depth. The process can be used to grind or pulverize the asphalt pavement as well as underlying layers on-site.
WHEN WOULD WE RECOMMEND RECLAMATION?
Like asphalt milling, reclamation has numerous applications. The following list does not include every possible use of asphalt reclamation, but it covers the most common situations in which we would recommend reclamation instead of milling.
• When the work site is a great distance from the asphalt plant. Reclamation can reduce hauling fees for the old asphalt. Old materials can be recycled in place.
• When the base or sub-base has become unstable. The base courses can be accessed and old materials can be recycled in place to create a stabilized foundation.
• When the pavement needs to have its load-bearing capacity improved.
• When the sub-grade needs to have its resistance to frost heave improved.
• When the pavement is intended for low or medium volumes of traffic. Although asphalt reclamation has been used on highways and interstates successfully, it is more common to use the procedure on parking lots, residential streets or airstrips handling only lightweight aircraft.
As you can see, asphalt milling and asphalt reclamation have certain applications for which each is preferred although both can be used to remove existing pavement. The experts at APM can guide you through the selection process and help you determine which method is right for you. We also provide asphalt paving, curbing, asphalt pavement reinforcement, storm water management, pavement markings and many other services at affordable rates.
