APPENDIX F - GLOSSARY AASHTO - American Association of State Highway Transportation Officials AADT - The Annual Average Daily Traffic - can refer to one-way or two-way traffic. Annual Costs - Any cost associated with the annual maintenance and repair of the facility. Asphalt Emulsion Mix - A mixture of emulsified asphalt materials and mineral aggregate usually prepared in a conventional hot-mix plant or drum mixer at a temperature of not more than 260°F (127°C). It is spread and compacted at the job site at a temperature above 200°F (93°C). Cape Seal - A thin wearing course that involves the application of a slurry seal a few days after placing a chip seal. Cape seals are used to provide a dense, waterproof surface with improved skid resistance. Chip Seal - A thin wearing course in which a pavement surface is sprayed with asphalt (usually emulsified), then immediately covered with aggregate and rolled. Chip seals are used primarily to seal the surface of a pavement which has non load-associated cracks, and to improve surface friction. They are also used as a wearing course on low-volume roads. Cold In-Place Recycling (CIR) - A process in which a portion of an existing bituminous pavement is pulverized or milled, the reclaimed material is mixed with new binder and virgin materials, and the resultant blend is placed as a base for a subsequent overlay. Emulsified asphalt is especially suited for cold in-place recycling. Although not necessarily required, a softening agent may be used along with the emulsified asphalt. Cold Milling - A process of removing pavement material from the surface of the pavement either to prepare the surface (by removing rutting and surface irregularities) to receive overlays, to restore pavement cross slopes and profile, or to re-establish the pavement’s surface friction characteristics. Crack Filling - A maintenance procedure that involves placement of materials into non-working cracks to substantially reduce infiltration of water and to reinforce the adjacent pavement. Crack filling is not the same as crack sealing. Crack Sealing - A maintenance procedure that involves placement of specialized materials, either above or into working cracks, using unique configurations to reduce the intrusion of debris into the crack, and to prevent intrusion of water into the underlying pavement layers. Dense-Graded Asphalt Overlay - An overlay course consisting of a mix of asphalt cement and a well-graded (also called dense-graded) aggregate. A well-graded aggregate is uniformly distributed throughout the full range of sieve sizes. Emulsified Asphalt - A mixture of asphalt cement and water, which contains a small amount of an emulsifying agent. Emulsified asphalt droplets, which are suspended in water, may be either the anionic (negative charge) or cationic (positive charge) type, depending upon the emulsifying agent. Fog Seal - A light application of slow setting asphalt emulsion diluted with water. It is used to renew old asphalt surfaces and to seal small cracks and small surface voids.
