Why does concrete crack?
All concrete pavement cracks due to shrinkage as new concrete cures or due to loading during the concrete’s life. Occasionally a crack does not form at a sawcut location leading to a non-working joint. A key to identifying a non-working joint is that there is no movement between the two sides of the joint. The joint will be uniform in width, cannot open and close due to temperature change and will not have any elevation difference between the two sides of the joint. If unsure if a joint is working or non-working, treat it as a working joint.
What is the difference between a chip seal and an alligator crack?
The typical repair method, however; is to complete a partial-depth or full-depth patch. Full-depth cracking extends through the entire pavement structure, whereas partial-depth cracking goes through a portion of the pavement.
What is the condition of an alligator crack?
The condition of alligator cracking is reached when irregular longitudinal cracks begin to interconnect to form a series of small blocks that resemble an alligator’s skin. This distress is associated with traffic loading and is usually rooted in poor construction, poor drainage, subgrade failure, or the pavement may have just reached the end of its life. If neglected, full-depth distress can be observed when subgrade material is forced up through the surface leading to depressed pavement and an eventual pothole.
What are potholes in a road?
Potholes are voids in the roadway surface where pieces of the pavement have become dislodged. Areas in which many potholes occur become suspect for fundamental problems such as inadequate drainage, pavement strength, or base/subgrade problems. Single or infrequent potholes may be the only pavement distress to occur in an area, and beyond the treatment of the individual pothole no other pavement repair work may be required. If potholes occur in a systematic or cyclic manner, these are typically a result of the construction process.

Why does asphalt turn gray?
Oxidation causes asphalt to fade and turn gray, especially if it is at least a few years old. Fresh asphalt generally has a rich black color, due to the element called bitumen, a tar-like substance used as binder that holds together the aggregates in asphalt mixes. With constant exposure to the sun, bitumen slowly evaporates, while leaving behind the aggregates. This gives asphalt a faded appearance and indicates it is becoming brittle as it dries out. Unfortunately, the fading is often uneven, which means that some sections might appear darker or lighter than others, making the surface of your asphalt look unsightly.
