A hard, black petroleum-based material used to pave roads Asphalt can be mixed with recycled tires to make roads last longer
It is brittle, of a black or brown color and high luster on a surface of fracture; it melts and burns when heated, leaving no residue
A bituminous material employed in roofing materials because of its waterproofing ability
a dark bituminous substance found in natural beds and as residue from petroleum distillation; consists mainly of hydrocarbons mixed asphalt and crushed gravel or sand; used especially for paving but also for roofing cover with tar or asphalt; "asphalt the driveway
various bituminous substances, both naturally occurring and resultant from petroleum processing; also a bituminous substance mixed with crushed rock for paving
an organic bituminous compound used in the manufacturing of composition shingles
A bituminous waterproofing agent applied to roofing materials during manufacture
mixed asphalt and crushed gravel or sand; used especially for paving but also for roofing
A composition of bitumen, pitch, lime, and gravel, used for forming pavements, and as a water-proof cement for bridges, roofs, etc
Asphalt is a black substance used to make the surfaces of things such as roads and playgrounds. = tarmac. a black sticky substance that becomes hard when it dries, used for making the surface of roads (aspaltus, from asphaltos). Black or brown petroleum-like material that has a consistency varying from viscous liquid to glassy solid. It is obtained either as a residue from the distillation of petroleum or from natural deposits. Asphalt consists of compounds of hydrogen and carbon with minor proportions of nitrogen, sulfur, and oxygen. It softens when heated and is elastic under certain conditions. Used principally in road surfacing, asphalt is also used for roofs, coatings, floor tilings, and waterproofing, and in industrial products
Originally a naturally occurring product in use for centuries the early 1900's brought today's refined petroleum product This term is often applied to almost any asphalt product from H M A C to asphalt cements and oils
A substance left as a residue after evaporating or otherwise processing crude oil or petroleum Asphalt can be refined to conform to various roofing grade specifications: Dead-Level Asphalt: A roofing asphalt conforming to the requirements of ASTM Specification D 312, Type I This asphalt is for use in roofs which do not exceed a ¼ in 12 slope (2%) Flat Asphalt: A roofing asphalt conforming to the requirements of ASTM Specification D 312, Type II This asphalt is for use in roofs which do not exceed a ½ in 12 slope (4%) Steep Asphalt: A roofing asphalt conforming to the requirements of ASTM Specification D 312, Type III This asphalt is for use in roofs which do not exceed a 3 in 12 slope (25%) Special Steep Asphalt: A roofing asphalt conforming to the requirements of ASTM Specification D 312, Type IV This asphalt is for use in roofs which do not exceed a 6 in 12 slope (50%)
Often used as an abbreviation for asphalt concrete. A hard ground covering used for roads and walkways
Black to dark brown solid or semisolid bituminous material which gradually liquifies when heated, produced from distillation residues of crude petroleum, or occuring naturally
A dark-brown to black cement-like material obtained by petroleum processing, containing bitumens as the predominant constituents Includes crude asphalt as well as the following finished products: cements, the asphalt content of emulsions (exclusive of water), and petroleum distillates blended with asphalt to make cutback asphalts
