Asphalt Paving

There are a multitude of options when it comes to maintaining or repairing your asphalt parking areas.  Below you’ll find a quick overview of the more extensive repair options available to you.

Overlay
New paving
Milling & Overlay

Overlay

Asphalt overlays are a method of paving 2-3” of new asphalt over the existing asphalt. Overlays extend the life of pavement that is still in serviceable condition. Overlays are particularly useful, when the existing asphalt is inadequate in depth.  Overlays are a popular approach because of their value.

  • Things to consider for an Overlay are:
    • The existing asphalt should be still in serviceable condition.
    • Overlays work best when there is a solid subgrade and an adequate asphalt base course to support the new asphalt.
    • How will the overlay affect the drainage? (Most overlays will not correct major drainage issues.)
    • The depth and number of cracks in the existing asphalt. Cracks may reflect through the new overlay in time. Deep cracks may need to be repaired prior to an overlay.
    • Pavement failures need to be repaired prior to overlays.

 

Ask a DACS  Estimator/ Consultants about edge milling to better blend to the existing layout.

New paving

First, the sub grade and base materials are graded and compacted to support the asphalt. Then new asphalt is paved generally 4-6″ deep in the parking areas. Drive-lanes or dumpster areas usually paved 6-8″ deep for heavier traffic and vehicles. The asphalt is placed and compacted in lifts to the proper density.

  • The benefits of new paving are, that it ensures the subgrade is properly compacted, it creates a uniform pavement, it is easier to match the existing concrete, and it can correct many drainage issues.
  • New pavement has an estimated life of 20-30 years if you are following a reliable maintenance program.

Milling and Overlay

Mill and Overlay (cold planning/asphalt milling) is the process of removing the worn top layer of the existing asphalt by grinding/planning it, and then paving 2-3” of new asphalt on top.

  • It is recommended to perform a mill and overlay if the current asphalt is at least 5-6″ deep.
  • Mill and Overlays are easier to blend into an existing layout.
  • Mill and Overlays are used in parking lots and streets in an effort to create a “perpetual pavement” where the Mill grinds off the top of worn layer of asphalt and places new asphalt. This is significantly more cost-effective way than performing a full depth asphalt removal and replacement. Often, 1/3 of the cost.
  • While asphalt mill and overlays are hugely in demand, they will not significantly change the current drainage plan, they need a stable sub grade, and if the asphalt is too deteriorated, it will require a full depth asphalt removal and replacement.
  • The newly milled and overlayed pavement will increase the life expectancy by 50%.
  • Mill and Overlay’s need to be done before it has any significant deterioration to get the economic benefits of the process.
