Pavement failure occurs when an asphalt surface no longer holds its original shape and develops material stress which causes issues. Pavement failure issues include cracking, potholes, depressions, rutting, shoving, upheavals, and ravelling.

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.

Sealcoating is an important step in properly maintaining asphalt to ensure that your investment will last for years to come. During the sealcoating process, asphalt bitumen is sprayed across the surface to replace the layer that has worn down over time. Sealcoating will protect your asphalt surface from water intrusion, which would cause cracking and further disrepair.

Asphalt bitumen is a binding organic material made from the by-products of refined crude oil. Asphalt bitumen is used in road construction because it is easy to produce, reusable, non-toxic, and a strong binder.

Paving technology has advanced dramatically since the first paved road allowed for wheeled carts. Over the years, builders have used everything from stone slabs to concrete. Some of the earliest roads included feats of engineering that would be difficult to implement, even today.

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.

After a roadway has reached a level of disrepair that can not be fixed, the surface must be ripped up and replaced. Because asphalt surfaces are made of simple input materials, an old asphalt surface can be recycled to be used in new paving projects and other construction materials.
Details
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.

Whether it is a nuisance on your morning commute or it almost caused an accident, potholes should be repaired. The Public Works Department of a city is in charge of repairing potholes and often they do not assess that a road needs repair until a report has been filed.

Concrete flatwork is any poured surface that moves along a horizontal plane. Flatwork surfaces include patios, walkways sidewalks, foundations, driveways and any other flat surface. Concrete is the choice material for flatwork due to how it can achieve a perfectly flat and even surface with it.
