"Raveling" is the slow deterioration of asphalt caused when the aggregate materials pull away from the binder, allowing bits of pavement to blow and wash away. Over time, the pavement becomes thinner and more susceptible to cracking from the weight of vehicles. The guide below provides an overview of this issue to help you protect your paved areas.

What Causes Raveling?

Raveling is exacerbated by ice, snow, rain, and sunlight, all of which cause wear and tear on asphalt. Ultraviolet (UV) radiation causes oxidation, a process similar to rust formation on metals, which refers to the gradual loss of electrons that breaks down the chemical bonds holding aggregate materials together.

Raveling can also arise from physical damage, such as scrapes from snowplows positioned too low and the weight of heavy vehicles. Poor installation and the use of inferior gravel and sand also make a surface more prone to this issue. For example, during installation, pavers should evenly distribute the aggregate materials and fully mix the asphalt particles to create solid bonds that withstand wear and tear.

How Can You Prevent Raveling?

Sealcoating helps prevent this issue by acting as an additional binding agent that holds the asphalt components together. Have this service performed after installation and again every year to seal out the elements and keep asphalt surfaces from breaking down.

If an area develops cracks or potholes, professionals provide patching and infrared heating to prevent the fissures from expanding. Using specialized equipment, they heat the pavement’s surface to make it malleable, allowing technicians to rake and restore the bonds of the asphalt.
