Glossary

  • Asphalt: A mixture of aggregates (such as crushed stone, gravel, sand) and bitumen used for paving roads, driveways, and other surfaces.

  • Bitumen: A sticky, black, and highly viscous liquid or semi-solid form of petroleum used as the binding agent in asphalt paving.

  • Pavement: The surface layer of a road, sidewalk, or driveway, which can be made of various materials, including asphalt.

  • Hot Mix Asphalt (HMA): Asphalt mixture produced at a high temperature that is commonly used for road construction and resurfacing.

  • Cold Mix Asphalt: Asphalt mixture that can be used at lower temperatures and is often used for temporary repairs and patching.

  • Paver: A machine used in asphalt paving to lay the hot mix asphalt evenly and compact it to create a smooth surface.

  • Compaction: The process of compressing the asphalt material with heavy rollers to achieve the desired density and strength.

  • Base Course: The layer of material (typically aggregate) placed beneath the asphalt surface to provide stability and support.

  • Subbase: A layer of material placed below the base course to improve the pavement’s load-bearing capacity and drainage.

  • Binder Course: A middle layer of asphalt between the surface course and base course that provides additional strength and durability.

  • Surface Course: The top layer of asphalt pavement, designed to withstand traffic wear and provide a smooth driving surface.

  • Crack Sealing: The process of filling or sealing cracks in the asphalt surface to prevent moisture infiltration and further damage.

  • Striping: The application of painted lines, symbols, and markings on the asphalt surface for traffic guidance and safety.

  • Resurfacing: The process of applying a new layer of asphalt over an existing pavement to restore its condition and extend its lifespan.

  • Milling: Removing the top layer of an old asphalt surface to prepare it for resurfacing or to adjust its thickness.

  • Curb and Gutter: Concrete structures at the edge of the road that provide drainage and support for the asphalt pavement.

  • Binder: The intermediate asphalt mix used in multiple layers to improve the pavement’s strength and durability.

  • Tack Coat: A thin layer of asphalt emulsion applied to the existing surface to help bond the new asphalt layer during resurfacing.

  • Aggregate: Crushed stone, gravel, sand, or other materials mixed with bitumen to create asphalt.

  • Compaction Density: The degree of compaction achieved in the asphalt layers, measured in terms of air voids and density.

  • Infrared Asphalt Repair: A method of repairing damaged asphalt by using infrared heat to soften the existing material before reworking and compacting it.

  • Rutting: Depressions or grooves in the asphalt surface caused by repeated heavy vehicle traffic.

  • Pothole: A depression or hole in the asphalt pavement caused by the wear and tear of traffic and weather conditions.

  • Slope: The incline or gradient of the road’s surface designed to facilitate water drainage.

  • Sealcoating: The application of a protective coating to the asphalt surface to enhance its longevity and appearance.

  • Asphalt Recycling: Reusing existing asphalt materials to create new pavement, reducing waste and conserving resources.

  • Shoulder: The edge of the road next to the travel lanes, often made of asphalt or a different material.

  • Compaction Roller: Heavy machinery used to compact and smooth the asphalt layers during construction.

  • Asphalt Batch Plant: A facility where asphalt is produced in batches before being transported to construction sites.

  • ADA-compliant: Refers to pavement or surfaces that comply with the Americans with Disabilities Act (ADA) standards, ensuring accessibility for individuals with disabilities.
