There are four key factors to asphalt repair and paving to make the finished product pavement last: (1) type and quality of the sub-base that the asphalt sits atop, (2) pavement thickness that is suitable for the type and volume of traffic, (3) craftsmanship and construction methods, and (4) proper drainage theory and implementation.

  • SUB-BASE. There is an important distinction between sub-base and base. The sub-base is the native soil that we want to build a pavement on. The base is the gravel material we import that the pavement will sit atop. All else equal, the worse the sub-base, the more effort we’ll need to put into constructing an appropriate base and pavement. It’s much harder to make pavement last on soft and wet sub-bases (think wetlands), than it is for dry and hard sub-bases. Increasing the aggregate size and total thickness of the base will lengthen the longevity of the pavement.
  • PAVEMENT THICKNESS. A residential driveway could be as thin as 2″. Municipal thoroughfares and highways can be 24″ or more. As a rule of thumb, the more traffic volume and heavier it is, the thicker the pavement is that will be required.
  • CONSTRUCTION METHODS. Proper heat, density (compaction) and joint construction (where the paver passes kneed together) all contribute to the longevity of a pavement. Irrespective of initial appearance, a knowledgeable contractor adhering to these issues will install a pavement that lasts longer.
  • DRAINAGE. The asphalt institute claims that the three biggest enemies of asphalt longevity are: “water, water and water.” It is imperative that the pavement is designed to allow water to get off of the surface or to strategically placed storm drainage structures.

Asphalt Paving FAQs

What time of year can paving be performed?

We perform paving projects year-round in the Puget Sound area, but we lose many more days to poor weather November through February than the rest of the year. The size of the project can determine the required weather conditions. Moisture, temperature and wind all contribute to how quickly the asphalt cools. We need to be able to get the material placed and properly compacted before it cools below 180-200 degrees.

Is an overlay better than “remove and replace?”

Each has its purposes and advantages. An overlay is certainly a cheaper alternative, but often will not last as long. When asphalt fails, it is usually the base below the asphalt that has failed first. If the asphalt is not removed, we don’t have the opportunity to correct the base failure problem. Overlays are often susceptible to so-called reflection cracking, where the cracks in the underlying pavement will “reflect” through and begin to show in the top layer.

What can be done to make my new pavement last the longest?

(1) A sturdy and well-compacted sub-base (2) A pavement thickness and mix design that is appropriate for the weight-load that will be using the pavement (3) Proper compaction to 92-95% density (4) Diligent maintenance in the years after it is placed, including filling cracks immediately and periodic seal coating.

Who makes your asphalt?

We purchase asphalt from various asphalt manufacturing plants around Puget Sound including Cemex (formerly Rinker), Lakeside Industries, Tucci and Sons, Woodworth and ICON.

How long before I can drive on it?

Typically, newly laid asphalt can be driven on within several hours. The colder the weather, the sooner it is traffic ready. We usually employ a “touch test.” If the surface is cool to the touch, it is ready to be driven on. However, asphalt will take several weeks to cure to its ultimate hardness and exposure to heavy trucks or equipment should be avoided if possible shortly after completion.
