This time on the Sunrise Asphalt blog we wanted to give you a one stop shop for industry terms and jargon — words you will come across while looking into asphalt paving contractors and our services. Now, any contractor worth their salt will be happy to explain each and every question, but if you want to better understand blog posts, brochures, or are just looking for a quick definition – hopefully this resource serves you well!
Interconnected cracks across an asphalt surface forming a series of small squares that resemble an alligator’s skin.
High quality hot mixture asphalt and high quality aggregate materials compacted into a solid sturdy surface, great for driving! Also known as just plain asphalt.
Asphalt Emulsion Slurry Seal
A mix of emulsified (a fine dispersion of minute droplets of one liquid in another in which it is not soluble) water, asphalt, aggregate, and mineral fillers produced to a slurry consistency put on to a pavement surface as a sealer.
Asphalt Fog Seal
Asphalt emulsion diluted with water, lightly applied to renew older asphalt, sealing small cracks and gaps.
A layer of asphalt and aggregate mixture laid over an existing pavement structure to restore it’s look and performance. Generally includes a leveling course/pavement milling to correct the contour of the older surface, and then followed by other courses to provide the needed thickness.
Asphalt is the building block of all we do here! Aggregate and asphalt compacted together over supporting layers of gravel, crushed stone, etc. All together it makes asphalt pavement!
A film of asphalt on the surface of the pavement caused by an upward movement of asphalt from inside the layers. Sometimes known as flushing asphalt.
The buckling or shattering of pavement, usually occurring at joints or transverse cracks.
Asphalt emulsion applied to existing asphalt pavement for asphalt preservation and skid resistance.
A simple separation in the pavement. Could be caused by natural causes such as weather, traffic, or caused by underlying problems in the base of the pavement.
The movement downward of pavement due to heavy load on the surface.
Low areas or divots of limited size. May or may not be accompanied by cracking.
The breaking up of pavement from its original shape and form.
A difference in elevation of two slabs at a joint or crack.
Full-Depth Asphalt Pavement
Asphalt pavement structure that uses asphalt mixtures for all layers above the subgrade or improved subgrade.
Hot Mix Asphalt
Asphalt cement and aggregate mixed together at a hot temperature.
Asphalt layer made by mixing aggregate and emulsified asphalt or cutback at the road site using a traveling plant, motor graders, and other special equipment.
Any mixture produced in an asphalt mixing plant. Made up of asphalt binder and mineral aggregate.
Aggregate particles in a pavement surface with edges that have been rounded and surfaces polished smooth by traffic.
The bane of our existence! But also, any bowl (or pot!)-shaped hole of varying sizes in the pavement.
The progressive separation of aggregate particles in a pavement from the surface downward or from the edges inward.
Reusing a material (usually after some sort of process) after it has already served its original intended purpose.
For asphalt that means recycling the old torn up asphalt and making new recycled mixes.
Cracks in asphalt overlay layers that mirror, or reflect, the crack pattern in the pavement structure underneath.
Channelized depressions that may develop in asphalt pavement, usually where wheels heavily traffic.
A thin asphalt surface treatment used to waterproof and improve the texture of an asphalt surface.
Any condition that contributes to making a pavement slippery.
Cracks, sometimes crescent-shaped, that point in the direction of the thrust of the wheels on the pavement. Caused by lack of bond between two layers of pavement.
The breaking or chipping of pavement at joints, cracks, or edges.
The upward displacement of pavement due to swelling of the subgrade or some portion of the pavement structure.
