A bituminous material employed in roofing materials because of its waterproofing ability.
Asphalt cement
Asphalt paving. Most commonly used for driveways, the type of soil underneath is very important. If there is good drainage, 4" of well-compacted asphalt may be all that is necessary. With clay, which has little drainage, the soil must be dug out and replaced with a 4" to 7" bed of gravel before laying 4" of asphalt. Must be installed before the ground freezes.
Asphalt emulsion
A mixture of asphalt particles and an emulsifying agent such as bentonite clay and water.
Asphalt felt
An asphalt-saturated and/or an asphalt-coated felt membrane.
Asphalt lute
Used for spreading and smoothing asphalt, this rake-like tool has a straight edge and a toothed side.
Asphalt mastic
Asphalt-based adhesive that is normally used in roofing.
Asphalt paint
Asphalt-based paint used for waterproofing.
Asphalt plastic cement
An asphalt-based cement used to bond roofing materials. Also known as flashing cement or mastic.
Asphalt roof cement
The proper name for Plastic Cement and Flashing Cement. Asphalt roof cement consists of solvent-based bitumen, mineral stabilizers, and other fibers (sometimes asbestos). Asphalt roof cement is categorized by ASTM standard D 2822-91 (1997) or for non-asbestos, ASTM standard D 4586-93.ÊPlastic Cement is for use on low-slope surfaces, conforms to ASTM Specification D 312, Type I; Specification D 449, Types I or II; or Specification D 946. Plastic Cement is self-sealing, adhesive and ductile and is classified by ASTM Standard D 2822-91 Asphalt Roof Cement, and D 4586-92 Asphalt Roof Cement, Asbestos-Free, Types I and II.ÊFlashing Cement can be used on vertical surfaces and has a high softening point, low ductility and conforms to the requirement of ASTM Specification D 312, Types II or III; or Specification D 449, Type III.
