The Roadrunner Paving and Asphalt Glossary Part 2
Concrete and asphalt paving is a complicated process that requires extensive technical training and experience. You don’t have to know as much as your paving contractor, but you do need to have a basic understanding of the terminology being used so you can have productive conversations with the contractor.
Here are more of the terms you are likely to hear from your concrete or asphalt contractor in Arizona and elsewhere:
Open-grade aggregate is a mix that has more space between the particles, which makes it easier for water to drain. This aggregate mix is used in areas that get a lot of storm water runoff. It is also a good choice for Arizona properties since most areas get hit hard by the annual monsoon season.
An overlay is a thin layer of asphalt placed over existing pavement. An overlay can renew the look of pavement and can help extend its life.
Parking blocks are placed at the front of parking spaces to prevent cars from bumping into walls or drifting into the road or other parking spaces.
Some projects use paving blocks instead of poured concrete or asphalt. The paving blocks are placed individually, usually in a pattern. Mortar can be used to lock the pavers and strengthen the surface.
A petromat overlay uses a geotextile fabric to slow down the cracking on areas that have been newly resurfaced.
Permaflex paving is used as an overlay for cracked surfaces. This paving uses a trademarked asphalt mix that is specially designed for this purpose.
Portland Cement Concrete
Portland Cement Concrete (PCC) is a uniform concrete that is characterized by its grayish-white color. It has a smooth surface achieved by a cement binder that leaves behind few exposed aggregates.
The gradual roughening of the asphalt surface is known as raveling. This occurs because the sandy particles in the aggregate are washed away, leaving behind the rougher stone. Raveling is not only an aesthetic issue; it can also leave the pavement vulnerable to structural damage.
Resurfacing involves putting a new layer of asphalt on your driveway or pavement to strengthen it and extend its life. If a driveway or pavement is cracked, worn out or aging, resurfacing is a necessity for preserving it. Resurfacing will not only protect your investment, but will also increase the value of your property.
Seal coating is the application of a protective coating on the asphalt to reduce damages. Seal coating is primarily used on driveways and parking lots, rather than roadways. It protects against damages from UV rays, water exposure, chemical spills (like oil and gas from cars), and aging. Seal coating should be performed every two to four years to get the maximum benefits.
Slurry is a thin mixture of water (or some other liquid) and fine substances such as clay, plaster of paris, or concrete.
Striping is used to direct the flow of traffic. The painted lines can divide lanes, mark off parking spaces, define crosswalks, and more. Striping is essential to maintaining safety for motorists and pedestrians. Fresh striping also improves the look of the pavement, which can bolster the value of the property. Fresh striping also helps to maintain a professional image for businesses.
Tack coating is applied to get a new layer of asphalt to adhere to an older layer. It can also bond concrete and other materials. Tack coating is essential to the long-term health of the pavement. If it is not applied, the new layer can shift, and structural damage can occur.
The wearing course of a road is the top layer that directly supports vehicle traffic. It is a smooth, solid layer that is designed to withstand heavy weights and to resist erosion from water runoff and other elements. Concrete pavement is a more durable choice for the wearing course, and it is easier to maintain, but it is also the most expensive option and takes longer to install. Bituminous pavement is cheaper and can be installed more quickly, but it also requires a lot of upkeep.
