Asphalt Paver laying down chip seal

What is Chip Seal?

Chip seal combines one or more layers of asphalt covered with one or more layers of crushed rocks known as aggregate. This is less expensive than straight asphalt resurfacing and is excellent for roads that are not in constant use or have a small amount of traffic. It is commonly used by Department of Transportation to maintain roads that are outside of metropolitan areas.

Cold Patch Vs Hot Asphalt

Over time any asphalt surface will break down from the environmental stress of rain and sunlight and the pressure strains of motor vehicle use. Small cracks can quickly expand on a paved surface with the intrusion of water or the degradation of a subgrade. When an issue occurs it is important to administer a repair of either a cold or hot asphalt patch.

What Is Asphalt Overlay?

Asphalt overlay is a paving method of applying a new layer of asphalt to a deteriorating surface. Rather than tearing up an old asphalt surface entirely, an asphalt overlay project will use the existing layers as a base for the new asphalt pavement. Some asphalt surfaces with severe damage like rutting, potholes, large cracks, and expansions will need to be milled before an overlay is applied.

Asphalt Maintenance

Asphalt maintenance like crack sealing, sealcoating, striping, and patching are low-cost solutions that will improve the life of an asphalt surface. If an asphalt surface is not maintained properly over time it can lead to a costly replacement. Use this guide to help you properly maintain blacktop pavement.

Colored Asphalt

An asphalt surface is typically called blacktop because of the color, but not all asphalt is black in color. This color of roads is determined by the input materials that consist of bitumen, an asphalt cement, and aggregate rock. Bitumen is always black, but there are paved surfaces that use dies and even different colored rock to pave with.
